Clock Riddles For Kids

I have a face but no eyes. I have hands but no fingers. I help you know when to eat and sleep. What am I? Answer: A clock. A clock has a face with numbers on it and hands that point to the time. Even though it looks like it has a face and hands, it cannot see or feel anything. It just keeps moving every second of the day.
I go tick and tock all day long. I never stop, not even for a song. What am I? Answer: A clock. The ticking sound a clock makes is caused by its moving parts inside. Every tick means one second has passed. It never takes a break, not even at night when you are sleeping.
I live on the wall in your kitchen. I tell you when it is time for lunch. What am I? Answer: A wall clock. A wall clock hangs on the wall and is easy to see from anywhere in the room. You can check it quickly to know if it is time to eat, go to school, or take a nap.
I am round like a pizza, but you cannot eat me. I have numbers all around my face. What am I? Answer: A clock. A clock is usually shaped like a circle with numbers from 1 to 12 placed all around it. Even though it looks round like food, it is made of metal or plastic and is used to tell time.
I have two hands that never shake anyone. They just move in a circle all day. What am I? Answer: A clock. The two main hands on a clock are the hour hand and the minute hand. They go around in circles without ever stopping. They point to the numbers to show you what time it is.
I buzz and beep to wake you up. I sit beside your bed at night. What am I? Answer: An alarm clock. An alarm clock is set to make a loud sound at a specific time. Most people place it on a nightstand next to their bed. It makes sure you wake up in the morning without being late.
I count the hours but never add them up. What am I? Answer: A clock. A clock shows the hours passing but does not add or multiply. It simply displays the current time. It is not a calculator, just a timekeeper.
I am small enough to sit on your wrist. I go with you everywhere you go. What am I? Answer: A watch or wristwatch. A wristwatch is a tiny clock you wear on your wrist with a band. It is very handy because you can check the time without stopping or looking around for a clock. It travels with you all day.
I have numbers but I cannot count. I have hands but I cannot clap. What am I? Answer: A clock. This is one of the most classic clock riddles for kids. A clock has numbers displayed on its face and moving hands, but it cannot do math or make sounds by clapping. It only shows time.
I am always moving but I never walk. I am always working but I never talk. What am I? Answer: A clock. A clock’s hands are always in motion, moving forward with every second. Even though it seems busy, it never speaks a word. It communicates only by showing you the time silently.
What has a heart that beats but feels nothing? Answer: A clock. The “heartbeat” of a clock is its ticking sound. Every tick is like one beat. But unlike a real heart, a clock has no feelings, no emotions, and no life. It just keeps on ticking.
I am found on phones, on walls, and on wrists. I am one of the most used things in the world. What am I? Answer: A clock. Today clocks are everywhere. Your phone shows the time, your microwave shows the time, and even your car has a clock. They are one of the most common objects in modern life.
I tell you when school starts and when to go to bed. What am I? Answer: A clock. Clocks control so much of a child’s daily life. School starts at a set time, meals happen at set times, and bedtime is decided by the clock. Children rely on clocks all day without even thinking about it.
I can be fast or slow depending on how you set me. What am I? Answer: A clock. You can adjust a clock to move forward or backward. Some clocks run fast and gain time, while others run slow and fall behind. A good clock is always set correctly to show the right time.
I never sleep, even when you do. What am I? Answer: A clock. While you are deep in sleep, the clock keeps working. It ticks through the night, counting every minute and hour. When you wake up, it has been tracking time the whole time you were resting.
I am not alive, but I can tell you something important every single day. What am I? Answer: A clock. Every day, a clock gives you important information about time. It tells you if you are running late, if it is time to eat, or if your favorite show is about to start. It is very useful even though it has no life.
I have twelve friends who visit me every single hour. What am I? Answer: A clock face. The twelve numbers on a clock face are like twelve friends. Every hour, the hour hand visits one of them. Each number represents an hour of the day or night.
I go around and around but never leave my spot. What am I? Answer: A clock’s hands. The hands of a clock spin in a circle around the center of the clock. They keep going around all day and night. Even though they are always moving, they stay in the same place on the clock face.
What runs all day but has no legs? Answer: A clock. A clock is always “running,” meaning it is always ticking and working. But unlike animals or people, it has no legs at all. It stays in one place and works from there.
I am broken when someone does not wind me up. What am I? Answer: A wind-up clock. Old-fashioned clocks needed to be wound up with a key. If you forgot to wind them, they would stop working. Today, most clocks use batteries or electricity instead.

Clock Riddles For Kids About Time

If it is 6 o’clock now, what time will it be in 9 hours? Answer: 3 o’clock. When you add 9 hours to 6 o’clock, you pass through 12 and start again from 1. So 6 plus 9 equals 15, and 15 minus 12 equals 3. The clock would show 3 o’clock on the next cycle.
How many seconds are there in one full day? Answer: 86,400 seconds. There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. Multiply 60 x 60 x 24 and you get 86,400. That is a very big number just for one day.
If the clock shows 10:15, what will it show 45 minutes later? Answer: 11:00. Add 45 minutes to 10:15. The minute hand moves from 15 to 60, which completes one full hour. So the time becomes 11:00 exactly. It is a simple addition problem on the clock.
How many times do the clock hands overlap in 12 hours? Answer: 11 times. You might think the hands overlap 12 times, but the 12th overlap happens right at the start of the next 12-hour cycle. So they actually meet each other exactly 11 times in a 12-hour period.
When can you add two to eleven and get one? Answer: When you add two hours to eleven o’clock. On a clock, after 12 comes 1. So 11 o’clock plus 2 hours equals 1 o’clock. This is a fun math trick that only works with clock time.
How many minutes are in one full day? Answer: 1,440 minutes. Multiply 60 minutes by 24 hours and you get 1,440. It sounds like a lot, but each minute passes very quickly. This is why it is important to use your time wisely.
How many times does a clock chime in 12 hours if it chimes once for each hour? Answer: 78 times. Add up 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12. That total equals 78. So in a 12-hour period, a chiming clock makes 78 chimes in total.
At what time do the hour and minute hands point in exactly the same direction? Answer: At 12:00. Both hands are at the exact same spot only at 12:00, pointing straight up. After that, the minute hand moves faster than the hour hand, so they are never perfectly aligned again until they meet at later times approximately every 65 minutes.
A clock gains 5 minutes every hour. How much time does it gain in one full day? Answer: 2 hours. If a clock gains 5 minutes each hour and there are 24 hours in a day, multiply 5 by 24. That gives you 120 minutes, which is the same as 2 full hours. This clock would show a time 2 hours ahead by the end of the day.
If you look at a clock at 12:00 and then again at 3:45, how many minutes have passed? Answer: 225 minutes. From 12:00 to 3:00 is 3 hours, which is 180 minutes. Then add 45 more minutes for the last part. 180 plus 45 equals 225 minutes total.
How many hours are there in one week? Answer: 168 hours. There are 24 hours in a day and 7 days in a week. Multiply 24 by 7 and you get 168. A week is a long time when you think of it in hours.
What time is it when an elephant sits on a clock? Answer: Time to get a new clock! This is a classic funny riddle. No clock can survive a sitting elephant. The real answer is that the clock is crushed and broken, so it is definitely time for a replacement.
A clock shows 6:30. Is the clock tired? Answer: Yes, it is hands down exhausted! This is a pun riddle. At 6:30, the hands of the clock point straight down. “Hands down” is also a saying that means something is clearly the best or most obvious. So the clock is “hands down” tired.
I tell you morning from night, and night from morning. What am I? Answer: A clock with AM and PM. A 12-hour clock repeats its numbers twice a day. AM stands for the hours from midnight to noon, and PM stands for noon to midnight. Together they help you know if it is day or night.
I only move forward, never backward. Even when the clock is changed, I keep going. What am I? Answer: Time. Time never stops or goes in reverse. Even when we change our clocks for daylight saving time, actual time keeps moving forward. No clock can change that fact.
How many times does the number 6 appear on a clock face? Answer: Once. There is only one number 6 on a standard clock face. The numbers go from 1 to 12 and each appears only one time. Even though the hands pass over each number many times, the number itself is printed only once.
What is always in front of you but cannot be seen? Answer: The future or time ahead. The future is always coming but you cannot see it. Time is always moving forward toward things you have not experienced yet. It is always ahead but never visible until it becomes the present.
Can you make 10 plus 4 equal 2? Answer: Yes, with a clock. Ten o’clock plus 4 hours equals 2 o’clock. On a clock face, time wraps around after 12. So 10 + 4 = 14, and 14 – 12 = 2. Clock math works differently from regular math.
How many times in one full day does the hour hand go all the way around the clock? Answer: Twice. The hour hand completes one full circle every 12 hours. Since a day has 24 hours, the hour hand goes around exactly twice per day. The minute hand, however, goes around 24 full times.
What goes up when time passes but never comes back down? Answer: Your age. Every year that passes adds one more year to your age. Unlike a clock that keeps repeating, your age only goes one way. Once a year passes, you cannot go back to being younger.

Classic Clock Riddles For Kids

What has a mouth but never talks, has a head but never thinks? Answer: A clock is often given parts of a body in riddle form, but here the classic twist refers to a river, yet clocks share this format. A clock has a face, hands, and a body, but none of them actually work like a human’s. It is purely a machine that measures time.
I have a face with twelve friends. We circle each other endlessly. What am I? Answer: A clock face. The clock face is the round dial with numbers 1 through 12. The hands spin around it endlessly. The numbers stay still while the hands keep moving around them without stopping.
What runs but never walks, has a mouth but never talks? Answer: A clock. This is one of the most famous riddles about clocks. A clock “runs” in the sense that it is always operating. It has a face with openings like a mouth, but it makes no sounds on its own unless it is an alarm or chime clock.
I stand still yet never stop moving. What am I? Answer: A clock. The clock itself does not move from its place on the wall or shelf. But its hands are in constant motion. This is the clever trick in the riddle. The clock is both still and always in motion at the same time.
What has hands but cannot hold anything? Answer: A clock. Clock hands are the moving parts that point to the numbers. But they are not real hands. They cannot pick up objects, wave, or shake another hand. They only point and rotate.
I have three hands but no arms. What am I? Answer: A clock with a second hand. Most clocks have two hands: the hour hand and the minute hand. Clocks that also show seconds have a third, thinner hand. All three spin around without any real arms attached.
I am not alive, but I keep moving every single second. What am I? Answer: A clock. Life requires breathing, eating, and growing. A clock does none of these things. Yet it is always in motion, never resting, never pausing. Its movement is powered by electricity, batteries, or springs.
What is always coming but never arrives? Answer: Tomorrow, or the next moment in time. No matter how long you wait, tomorrow never quite comes. Once you reach tomorrow, it has already become today. This riddle plays with the concept of time moving forward constantly.
I was old before I was new. I am used before I am made. What am I? Answer: Time. The past has already happened, making it “old.” But every moment of time is also “new” when it arrives. And we use time constantly before we fully understand what it is. It is one of the most philosophical clock riddles.
What has to be broken before it can tell the right time? Answer: An egg timer or hourglass. An hourglass uses sand falling from one chamber to another. You have to “break” the process by flipping it over to restart it. Some people say you break the egg timer’s stillness to make it work.
What stays where it is when it goes off? Answer: An alarm clock. When an alarm clock “goes off,” it means it starts ringing or beeping. Many people think “goes off” means it leaves or disappears, but the clock stays in the same place. It just starts making noise.
What can tell time without saying a word? Answer: A clock. Clocks are completely silent in how they share information, except for ticking or chiming sounds. They never use words. You just look at the face and read the time from the position of the hands.
The more you take from it, the longer it becomes. What is it? Answer: Time or a journey. As you take steps in a journey, the distance behind you grows longer. The same logic applies to time: as moments pass, the past grows longer and longer behind you.
I am made of numbers but I am not math. I am made of circles but I am not a ball. What am I? Answer: A clock. A clock has numbers displayed in a circular pattern, but it is not a math tool. It is also round in shape, but it is flat, not a sphere. Both things about it look like something else but are really just a clock.
I have no hands, yet I can tell time. What am I? Answer: A digital clock. A digital clock shows time using numbers on a screen instead of moving hands. Many phones, microwaves, and computers use digital clocks. They show the time clearly without any physical moving parts.
I am oldest in the morning and youngest at night. What am I? Answer: A day. A day is born at midnight and grows older with each passing hour. By night, it is almost over and nearly gone. The next day will be brand new, making the old day disappear completely.
I am always ahead of you, no matter how fast you run. What am I? Answer: The future or time. The future is always one step ahead. Even the fastest person in the world cannot catch up to what has not happened yet. Time always stays just in front of you.
What belongs to you but is used by everyone else more than you? Answer: Your time. Everyone else seems to demand your time: your boss, your teacher, your family, and your friends. But your time is truly yours. This riddle makes you think about how you spend the hours in your day.
What kind of clock is the most dangerous to take apart? Answer: A time bomb. A time bomb looks like a clock and uses a timer to set off an explosion. Taking one apart is extremely dangerous. This riddle uses wordplay between a regular clock and a ticking time bomb.
I hang on the wall and always know the truth. What am I? Answer: A clock. A clock always shows the accurate current time, as long as it is set correctly. In that sense, it always tells the truth. You can trust a good clock to give you the real time every time you look at it.

Funny Clock Riddles For Kids

Why did the clock get sent to the principal’s office? Answer: Because it was ticking too loudly! This is a funny school-themed riddle. In class, a clock that ticks too loudly can be very distracting. The joke imagines the clock getting in trouble for making too much noise during a lesson.
Why did the clock break up with the calendar? Answer: It felt like their time together was limited. This riddle plays on the word “time.” Both clocks and calendars deal with time. The punchline uses “time together” as a double meaning, referring to both their relationship and the actual concept of time running out.

What do you call a clock that is always hungry? Answer: A clock that goes back four seconds. The word “seconds” is used for both a unit of time and a second helping of food. So a hungry clock wants to go back and get more food, which is “four seconds.” It is a double-meaning joke.
What did the hour hand say to the minute hand? Answer: See you in an hour! The hour hand and minute hand meet at 12 and then separate. The hour hand moves slowly while the minute hand is faster. It takes about 65 minutes before they meet again, so the hour hand says it will see the other one in roughly an hour.
Why are clocks so good at comedy? Answer: Because they have great timing! Comedians say that timing is everything in a joke. Clocks are all about timing. So a clock would naturally be excellent at knowing the right moment to deliver a punchline.
What do you call a clock on the moon? Answer: A lunar tick. This is a pun on the word “lunatic,” which sounds like “lunar tick.” A clock that ticks on the moon would be a “moon tick” or “lunar tick.” It is a fun science and wordplay riddle rolled into one.

What time does a duck wake up? Answer: At the quack of dawn. The phrase “crack of dawn” means very early in the morning when the sun first rises. By replacing “crack” with “quack,” the riddle makes it about a duck. It is a funny animal twist on a time-related expression.
What time is it when the clock strikes thirteen? Answer: Time to get a new clock. Standard clocks only go up to 12. If a clock strikes 13, it is clearly broken. So the answer is that you need to buy a replacement clock immediately because yours is definitely not working right.
Why did the boy eat his clock? Answer: He was told it was time for dinner. This is a hilarious take on the phrase “time for dinner.” Instead of understanding it as a call to come eat, the boy literally thought he should eat the time itself by eating the clock.
What do you say to a clock that is always late? Answer: What is the matter with you, it is about time! This phrase uses “about time” to mean both that it is almost the right time and that the clock should be more responsible about keeping accurate time. It is a classic way to scold someone for being late.
Why did the clock keep laughing? Answer: Because someone kept tickling it. The ticking sound a clock makes is called a “tick.” If someone was “tickling” the clock, it might tick even more. This riddle connects the idea of being tickled and laughing with the natural sound a clock makes.
What do clocks eat for lunch? Answer: Minute rice and second helpings. This riddle uses clock-related words in a food context. “Minute rice” is a real food that cooks quickly. And “second helpings” means getting more food, but also refers to seconds on a clock. Together they make a perfect clock meal.
What did the digital clock say to the grandfather clock? Answer: Look, no hands! A grandfather clock has hands that move around its face. A digital clock shows time using numbers instead of hands. So the digital clock is bragging that it works perfectly without needing any hands at all.
Why does time fly when you are having fun? Answer: Because fun does not watch the clock. When you are bored, you keep checking the clock and time feels slow. But when you are having fun, you forget to look at the clock, so the hours seem to pass by in minutes.
What do you call a clock that you cannot stop laughing at? Answer: A clock with hands down the funniest face. The phrase “hands down” means clearly or obviously. And a clock has both hands and a face. So a funny clock is “hands down” the funniest face you have ever seen.

Tricky Logic and Math Clock Riddles

A clock shows 3:15. How many degrees are between the hour and minute hands? Answer: 7.5 degrees. At 3:00, the hour hand is exactly at 90 degrees. By 3:15, the hour hand has moved slightly forward because it moves 0.5 degrees per minute. In 15 minutes, it moves 7.5 degrees. The minute hand is at 90 degrees at 3:15. So 90 minus 82.5 equals 7.5 degrees between them.
At what time between 2 and 3 o’clock are the hands exactly together? Answer: At approximately 2:10 and 54 seconds. The minute hand starts at 12 and must catch up to the hour hand which is at the 2. Since the minute hand gains 5.5 minutes on the hour hand every hour, you divide 10 by 5.5 to find how many minutes it takes to catch up. The hands meet at about 10 minutes and 54 seconds past 2.
How many degrees does the minute hand move in 20 minutes? Answer: 120 degrees. A full circle is 360 degrees. There are 60 minutes in a full circle for the minute hand. So each minute equals 6 degrees of movement. Multiply 6 by 20 and you get 120 degrees. The minute hand moves a full third of the clock face in 20 minutes.
If a clock is set at 8:00 AM on Monday and gains 2 minutes per hour, what will it show at 8:00 AM on Tuesday? Answer: 8:48 AM. There are 24 hours from Monday to Tuesday. If the clock gains 2 minutes per hour, multiply 2 by 24 to get 48 extra minutes. So the clock would show 8:48 AM instead of the correct 8:00 AM.
How many right angles does the minute hand make in one hour? Answer: Four right angles. A right angle is 90 degrees. The minute hand makes a full 360-degree circle in one hour. Divide 360 by 90 to get 4. So the minute hand forms a right angle at the 12, 3, 6, and 9 positions during each hour.
A clock loses 5 seconds every 10 minutes. How much time does it lose in one day? Answer: 12 minutes. There are 1,440 minutes in a day. Divide 1,440 by 10 to get 144 groups of 10 minutes. Multiply 144 by 5 seconds to get 720 seconds. Convert 720 seconds to minutes by dividing by 60, and you get 12 minutes lost per day.
Between midnight and noon, how many times do the clock hands form a straight line? Answer: 11 times. The hands form a straight line both when they overlap and when they point in exactly opposite directions. They overlap 11 times in 12 hours and they point in opposite directions 11 times as well. But the question asks only about straight lines in one direction, so the answer is 11 overlaps.
If you look at a clock in a mirror, it shows 6:30. What is the actual time? Answer: 5:30. When you look at a clock in a mirror, the left and right sides are reversed. The clock shows 6:30 in the mirror, which is the mirror image of 5:30. To find the real time, subtract the mirror time from 12:00. 12:00 minus 6:30 gives you 5:30.
A train leaves at 7:40 AM and arrives 2 hours and 35 minutes later. What time does it arrive? Answer: 10:15 AM. Add 2 hours to 7:40 AM and you get 9:40 AM. Then add 35 more minutes to 9:40 AM and you get 10:15 AM. The train arrives at exactly 10:15 in the morning.
The hour hand moves how many degrees in 6 hours? Answer: 180 degrees. The hour hand completes a full 360 degrees in 12 hours. Divide 360 by 12 to find that it moves 30 degrees per hour. Multiply 30 by 6 hours and you get 180 degrees. In 6 hours, the hour hand has traveled exactly halfway around the clock.
If it is 11 o’clock now and you add 70 minutes, what time is it? Answer: 12:10. Add 60 minutes to 11:00 to reach 12:00. Then add the remaining 10 minutes to get 12:10. Adding 70 minutes takes you past 12 o’clock by 10 minutes.
A clock chimes once at 1:00, twice at 2:00, and so on. How many times does it chime in a full 24-hour day? Answer: 156 times. In 12 hours, the clock chimes 1+2+3+4+5+6+7+8+9+10+11+12 = 78 times. Since a day has two 12-hour cycles, multiply 78 by 2 to get 156 total chimes in a full day.
If a clock shows the same time forwards and backwards, what is that time called? Answer: A palindrome time. A palindrome reads the same forwards and backwards. Times like 12:21 or 10:01 are palindromes because the digits are the same when reversed. These are fun patterns to look for on digital clocks.
You have two clocks. One is broken and shows the same time always. The other loses one minute every day. Which one is more accurate over a year? Answer: The broken clock. A completely stopped clock is correct exactly twice a day. A clock that loses one minute every day takes 720 days to be exactly right again. So the stopped clock shows the right time more often within any given year.
How many times in 24 hours are all three clock hands, including the second hand, perfectly aligned? Answer: Approximately twice. The hour and minute hands align about 22 times per day. But for all three hands including the second hand to align perfectly is extremely rare and happens only about twice a day, near 12:00:00 and again at roughly the same moment 12 hours later.

Logical Clock Riddles For Students

John looked at the clock and saw the time was a reflection of the actual time. The clock showed 8:20. What was the real time? Answer: 3:40. To find the reflected time on a clock, subtract the shown time from 12:00. 12:00 minus 8:20 equals 3:40. If you imagine holding the clock up to a mirror, 8:20 becomes 3:40. Always subtract from 12 to reverse a clock reflection.
If you started counting from 1 and said one number per second, how long would it take to count to 3,600? Answer: One hour. There are 3,600 seconds in one hour. If you count one number per second starting at 1, you would reach 3,600 exactly at the 3,600th second. That means you would finish counting after precisely one hour of counting.
A clock takes 3 seconds to strike 3 o’clock. How long does it take to strike 12 o’clock? Answer: 33 seconds. When a clock strikes 3, there are 2 gaps between the 3 strikes. Each gap lasts 1.5 seconds. To strike 12, there are 11 gaps between the 12 strikes. Multiply 11 by 3 seconds, which gives you 33 seconds total.
Two clocks show the correct time on Monday at noon. One loses one minute per day and the other gains one minute per day. When will both show the correct time together again? Answer: After 720 days. The slower clock loses 1 minute per day, and the faster clock gains 1 minute per day. For both to show the correct time at the same time, the slower clock must lose 12 hours and the faster must gain 12 hours. That equals 720 minutes for each, which takes 720 days.
If you wake up at 8 AM and your clock is 15 minutes fast, what is the real time? Answer: 7:45 AM. If your clock shows 8:00 AM but it is running 15 minutes fast, the actual time is 15 minutes earlier. Subtract 15 minutes from 8:00 AM to get 7:45 AM. Always subtract for a fast clock and add for a slow clock.
A snail climbs 3 inches up a clock every minute but slides back 1 inch every time the minute hand passes it. If the clock is 12 inches tall, how long does it take the snail to reach the top? Answer: This is a trick question based on reasoning. Net gain per minute cycle is 2 inches. After 5 minutes it reaches 10 inches. In the 6th minute it climbs 3 more inches to reach 13 inches, which passes the 12-inch top. So it takes 6 minutes to reach the top.
Tom looks at a digital clock that shows 10:08. He turns it upside down. What does it show? Answer: 80:01. When you flip a digital display upside down, the numbers change. 8 becomes 8, 0 becomes 0, 1 becomes 1, and the colon stays. So upside down, 10:08 becomes 80:01. This is a fun trick that works with certain digital number displays.
A clock gains 1 minute every 2 hours. If it shows the correct time now, when will it next show the correct time? Answer: After 60 days. The clock gains 12 minutes per day. To be wrong by exactly 12 hours, it needs to gain 720 minutes. Divide 720 by 12 and you get 60 days. After 60 days, the clock will have gained exactly 12 hours and show the correct time again.
At what time are the hour and minute hands of a clock at right angles for the first time after 12 noon? Answer: At approximately 12:16 and 22 seconds. A right angle is 90 degrees. After 12:00, the minute hand moves faster than the hour hand. The minute hand needs to be 15 minutes ahead of the hour hand to form a 90-degree angle. This happens at about 16 minutes and 22 seconds past 12.
If a machine stamps one clock every 10 seconds, how many clocks does it stamp in one hour? Answer: 360 clocks. There are 3,600 seconds in one hour. Divide 3,600 by 10 to get 360. The machine stamps exactly 360 clocks in one full hour.
Sam’s clock runs backwards. It shows 5:00. What time is it really if it showed 12:00 at noon and has been running for 5 hours? Answer: 5:00 PM. If the clock runs backwards and started correctly at 12:00, after 5 hours of running backwards it would show 7:00. But since we need the real time, add the 5 hours forward to noon to get 5:00 PM. The real time is 5 in the evening.
A clock’s minute hand is at 12 and hour hand is at 6. How many degrees apart are they? Answer: 180 degrees. When the minute hand is at 12 and the hour hand is at 6, they are pointing in exact opposite directions. This creates a straight line, which is 180 degrees. This happens only at 6:00 and 6:00 on both the AM and PM cycle.
If a clock bell rings at 6 AM and every 30 minutes after that, how many times does it ring before noon? Answer: 13 times. Starting from 6:00 AM, count: 6:00, 6:30, 7:00, 7:30, 8:00, 8:30, 9:00, 9:30, 10:00, 10:30, 11:00, 11:30, and 12:00 noon. That is 13 rings from 6 AM up to and including noon.
A watchmaker charges $10 to fix a clock plus $2 per minute it takes. If the bill is $40, how long did the repair take? Answer: 15 minutes. Subtract the base fee of $10 from $40 to get $30 in labor. Divide $30 by $2 per minute to get 15 minutes. The repair took exactly 15 minutes.
Sarah was born at the first second of the year and her twin was born at the last second. How many days apart are their birthdays? Answer: Almost 365 days. Sarah is born on January 1st at the very start of the year. Her twin is born on December 31st at the very end of the year. Although they are twins, their birthdays fall almost one full year apart on the calendar.

Clock Riddles With Answers

I have a face and two hands but no body. What am I? Answer: A clock. A clock has a round face with numbers and two hands, but it has no actual body. It is a machine, not a living creature. The word “hands” and “face” make it sound like a person, which is the trick of the riddle.
I move without legs, I speak without a mouth, I count without numbers. What am I? Answer: Time itself. Time moves forward constantly without any physical legs. It communicates in the sense that we feel it passing. And it counts moments without using any actual numbers out loud. Time is invisible but always present.
What has a tick but is not a bug? Answer: A clock. A tick is an insect that clings to animals. But a clock also “ticks,” making that familiar ticking sound with each passing second. This riddle plays on the double meaning of the word tick.
I am always on time but never early or late. What am I? Answer: A perfectly accurate clock. A good clock never shows a time before or after the real time. It is always exactly right. This is the goal of every clock and watchmaker, to create a timepiece that is always perfectly on time.
I have no beginning and no end. I am always with you. What am I? Answer: Time. There is no point at which time started or where it will end. Even before you were born, time was passing. And after you are gone, it will keep going. Time has no beginning or end.
I am invisible, yet I am the most valuable thing in the world. What am I? Answer: Time. You cannot see time or hold it in your hands. But it is more valuable than gold or money. Once time is spent, you can never get it back. That makes it the most precious resource anyone has.
I go forward, never backward. Even if you wanted me to stop, I would not. What am I? Answer: Time. Nothing can make time go backward. Scientists have not found a way to reverse it. Even clocks that we wind back during daylight saving time do not change real time. Time just keeps marching forward always.
I am both the oldest and the youngest thing at the same moment. What am I? Answer: The present moment. Right now is brand new, making it the youngest possible moment. But it is also the most recent point of all time that has passed, making it old. The present moment is always both new and part of history.
I am the one thing that cannot be saved no matter how hard you try. What am I? Answer: Time. Money can be saved in a bank. Food can be saved in a fridge. But time cannot be stored. Once a second passes, it is gone forever. You can use time wisely, but you can never save it.
I tell you what you missed and what is yet to come. What am I? Answer: A clock combined with a calendar. A clock tells you what hours have passed and what hours remain in the day. A calendar tells you what days have passed and what dates are still ahead. Together they map out your life.
I have no weight, no color, and no smell. But I am the thing most people wish they had more of. What am I? Answer: Time. You cannot weigh time on a scale or see it or smell it.

Clock Riddles for Adults

I witnessed your birth and I will witness your end. I never judge and never forget. What am I? Answer: Time. From the moment you are born until the moment you die, time is always present. It witnesses every event in your life without making any judgment. And unlike humans, time has a perfect memory because history is recorded in its passage.
I make kings humble and the mighty fall. I heal the deepest wounds and undo the proudest achievements. What am I? Answer: Time. No matter how powerful a person is, time eventually brings them down. Time heals emotional pain that feels unbearable. And the greatest empires eventually crumble with the passage of enough time. Nothing is permanent against time.
I am the one thing every human has equally, yet no one seems to manage well. What am I? Answer: Time. Every person on Earth has the same 24 hours in a day. Rich or poor, young or old, everyone gets exactly the same amount. Yet nearly everyone struggles to manage it properly. Time is the great equalizer.
The more you try to use me, the faster I seem to go. The more you sit idle, the slower I seem to pass. What am I? Answer: Time. When you are busy and engaged in something interesting, time seems to speed by. When you are bored and doing nothing, every minute feels like forever. Time does not actually change speed, but our perception of it does.
I am the only thing you can give freely without ever running out, yet I am also the only thing that is always running out. What am I? Answer: Time. You can give your time to others freely, spending it on them without charge. But the overall amount of time in your life is always running out. You can share it, but you can never replenish it.
I was here before the mountains and I will be here after the stars burn out. What am I? Answer: Time. The mountains took millions of years to form. Stars burn for billions of years before going dark. But time existed before any of these things and will continue after all of them are gone. Time is older than anything in the universe.
I teach without speaking, I judge without seeing, and I punish without intent. What am I? Answer: Time. Time teaches lessons through experience. Over time, people learn what works and what does not.

People on their deathbeds often say they wish they had not wasted so much time on unimportant things. Yet the time they spent with loved ones and on meaningful experiences becomes the most cherished memory of all.

Hard Clock Riddles With Answers

A clock is placed facing a mirror. The clock shows 8:20. What time does the mirror reflect? Answer: 3:40. In a mirror, the image is reversed left to right. For a clock, you subtract the displayed time from 12:00. 12:00 minus 8:20 equals 3:40. If you were to look at 3:40 on a real clock and reflect it, you would see 8:20.
Two clocks show the exact same time right now. One loses one second per minute and the other gains one second per minute. After how many hours will they show the same time again? Answer: After 360 hours. The two clocks diverge at a rate of 2 seconds per minute, or 120 seconds per hour. For both to show the same time again, they must be 12 hours or 43,200 seconds apart in total divergence. Divide 43,200 by 120 to get 360 hours.
A clock pendulum swings back and forth once every 2 seconds. How many full swings does it complete in 24 hours? Answer: 43,200 full swings. A full swing means back and forth. That is one complete oscillation every 2 seconds. There are 86,400 seconds in a day. Divide 86,400 by 2 to get 43,200 full back-and-forth swings in one day.
Between 6:00 and 7:00, at what exact time are the clock hands pointing in exactly opposite directions? Answer: At 6:00 exactly. At 6:00, the hour hand points straight down to the 6 and the minute hand points straight up to the 12. These two directions are exactly opposite, creating a straight 180-degree line. This is the only moment between 6:00 and 7:00 where they are perfectly opposite.
If a clock face is divided into thirds, and each third contains four numbers, how many degrees are in each third? Answer: 120 degrees. A full clock face is 360 degrees. Divide it into three equal thirds. Each third covers 4 numbers out of 12 total. So each third is one-third of 360 degrees, which equals exactly 120 degrees per section.
A clock runs 15 minutes fast per day. How many days will it take before it shows the correct time again, assuming it started correctly? Answer: 96 days. The clock gains 15 minutes per day. To gain 24 hours, which is 1,440 minutes, divide 1,440 by 15. The answer is 96 days. After 96 days, the fast clock will have gained exactly 24 hours and show the correct time again.
If the second hand of a clock makes 60 full revolutions in one hour, how many degrees does it travel in 5 minutes? Answer: 1,800 degrees. In one minute, the second hand makes one full revolution of 360 degrees. In 5 minutes, it makes 5 full revolutions. Multiply 5 by 360 to get 1,800 degrees total traveled in 5 minutes.
A clock has a hidden chamber. Inside the chamber, a smaller clock runs at exactly half speed. If the outer clock shows 4 hours have passed, how much time has passed on the inner clock? Answer: 2 hours. If the inner clock runs at half speed, it ticks twice as slowly as the outer clock. When the outer clock counts 4 full hours, the inner clock has only completed 2 hours. This is similar to the concept of time dilation in physics.
At how many times in a 12-hour period do all three hands of a clock, hour, minute, and second, align? Answer: Approximately 2 times near 12:00:00 and 12:00:00 PM. The three hands truly align almost exclusively at 12:00:00. In practice, they are only perfectly aligned at the top of each 12-hour cycle because the second hand is at 12 for only a fraction of a second.
A broken clock that shows no hands can still be right. How? Answer: If the clock always shows 12:00:00, it is right twice a day. A clock with no hands shows no time at all, but if it displays a blank face, you could argue it is ambiguous. If a digital clock with broken hands always reads 12:00, it is exactly correct at midnight and noon.
A man has a clock that neither gains nor loses time. But it stopped 3 hours ago and he did not notice. He now looks at it and thinks it is correct. What is the earliest possible time it could actually be? Answer: 3 hours after any time the clock shows. If the stopped clock shows 4:00 and he looks at it now thinking it is correct, the real time is 7:00. The clock stopped 3 hours ago, so real time is always 3 hours ahead of what the stopped clock shows.
How many degrees does the hour hand of a clock move in 10 minutes? Answer: 5 degrees. The hour hand moves 360 degrees in 12 hours. That is 30 degrees per hour or 0.5 degrees per minute. In 10 minutes, multiply 0.5 by 10 to get 5 degrees. The hour hand moves very slowly compared to the minute hand.
Two clocks are set correctly at noon. Clock A gains 2 minutes every hour. Clock B loses 1 minute every hour. When will Clock A show a time that is exactly 1 hour ahead of Clock B? Answer: After 20 hours. Clock A gains 2 minutes per hour and Clock B loses 1 minute per hour. Together they diverge at 3 minutes per hour. For Clock A to be 60 minutes ahead of Clock B, divide 60 by 3. The answer is 20 hours.
A clockmaker winds up 5 clocks every 3 hours. How many total windings happen in a 24-hour day? Answer: 40 windings. Divide 24 hours by 3 hours to get 8 winding sessions per day. In each session, 5 clocks are wound. Multiply 8 by 5 to get 40 total winding actions in one full day.
A clock tower rings once at 1, twice at 2, and so on. It also rings once every half hour. How many times does it ring between noon and midnight? Answer: 90 rings. From noon to midnight is 12 hours. The hour rings total 1+2+3+4+5+6+7+8+9+10+11+12 = 78 rings. The half-hour rings add one ring every half hour for 12 half hours, which equals 12 more rings. Add 78 plus 12 to get 90 total rings.

Easy Clock Riddles for Kids

What has a face that you look at every day but cannot talk to? Answer: A clock. The face of a clock is the round part with numbers on it. You look at it many times a day to find out the time. But unlike a person’s face, a clock face cannot speak, smile, or respond to you.
I am always moving but you cannot see me move. What am I? Answer: The clock hands. The hands of a clock move so slowly that you cannot see them move just by watching. But if you look away and look back a minute later, they have moved. It happens too slowly for your eyes to catch in real time.
What do you call a clock that wakes you up? Answer: An alarm clock. An alarm clock has a special setting that makes it ring or beep at a chosen time. Most people use them to wake up in the morning. Without an alarm clock, many people would sleep too long and miss school or work.
I have no voice, yet I tell you many things each day. What am I? Answer: A clock. A clock cannot speak, but it tells you the time silently. You read the time by looking at where the hands point. It communicates important information without making any words at all.
I spin in circles all day. What part of me is this? Answer: The clock hands. The hands of a clock are always spinning in a circle called clockwise motion. They go around and around the clock face without ever stopping. This is where the word “clockwise” comes from.
I tell you when to wake up and when to go to bed. What am I? Answer: A clock or alarm. Clocks and alarms control our daily schedules. Parents set bedtimes based on the clock. Schools start at clock times. Even meals happen at certain clock-based hours. The clock is the manager of our daily life.
What is long when you are bored and short when you are happy? Answer: Time. When you are bored, time seems to drag on forever and each minute feels like an hour. But when you are having fun, hours fly by and feel like minutes. This is a well-known feeling that everyone relates to.
I am a clock that you flip upside down to reset. What am I? Answer: An hourglass. An hourglass has two glass chambers connected by a narrow neck. Sand flows from the top chamber to the bottom one. When all the sand falls, you flip it over to start timing again. It was used long before modern clocks.
What kind of clock never needs batteries or electricity? Answer: A sundial. A sundial uses the shadow of the sun to tell time. It works entirely on natural sunlight. It does not need to be plugged in or have batteries replaced. It is one of the oldest clocks ever invented by humans.
I am on your phone but you almost never call me by my name. What am I? Answer: The clock app. Every smartphone has a clock app built into it. People use it for alarms, timers, and checking the time. But most people just say “check the time” rather than using the word clock. It is always there but rarely named.
I run on the wall and help you get everywhere on time. What am I? Answer: A wall clock. A wall clock is mounted on a wall in homes, schools, offices, and restaurants. It is easy to see from across the room. It helps everyone in the space stay on schedule without needing to check their phone.
What has numbers but cannot count and has a face but cannot see? Answer: A clock. A clock has numbers printed on its face, but it does not know math. It has a face with markings, but it has no eyes to look around. Both features seem human-like but are purely mechanical.
I am louder in the morning and quieter at night. What am I? Answer: An alarm clock. In the morning, an alarm clock rings loudly to pull you out of sleep. At night, it sits quietly on the nightstand waiting for its alarm time. The same clock behaves very differently at different times of day.
I can be digital or I can have hands. Either way, I do the same job. What am I? Answer: A clock. Clocks come in two main types. Analog clocks use hands to point to numbers. Digital clocks show numbers directly on a screen. Both do the exact same job of showing you the current time. They just look and work differently.
What is always ticking but never a bomb? Answer: A clock. A ticking bomb and a ticking clock both make a tick sound. But a clock is perfectly safe. It is simply counting seconds. Only in movies and stories do people confuse the two. A regular clock just ticks along peacefully.

Advanced Time and Pattern Riddles

At what time between 3 and 4 o’clock are the hands of a clock equidistant from the 6? Answer: At 3:27 and 16 seconds approximately. At this time, the hour hand and minute hand are placed symmetrically around the 6 on the clock face. This requires calculating the exact positions of both hands and finding the moment when they are equal distances from the 6.
A clock is checked at 5 PM and is 10 minutes slow. At 11 PM it is 5 minutes fast. When did it show the correct time? Answer: At 9 PM. The clock moved from being 10 minutes slow to 5 minutes fast in 6 hours. That is a gain of 15 minutes over 6 hours or 2.5 minutes per hour. Starting 10 minutes slow, it takes 4 hours to gain those 10 minutes and reach the correct time. Add 4 hours to 5 PM to get 9 PM.
How many times in 24 hours does a 12-hour clock show a time where all the digits are different? Answer: This requires listing all times from 1:23 to 9:58 where no digit repeats across the hour and minute display. There are 360 such moments in a 12-hour period, meaning 720 in a full 24-hour day.
A clock pendulum swings from left to right in 1 second and from right to left in 1 second. How many total movements does it make in exactly one day? Answer: 86,400 individual swings. Each one-second movement counts as one swing. There are 86,400 seconds in a day. So the pendulum makes exactly 86,400 individual left or right swings during a full 24-hour period.
If you stare at a clock for exactly one hour, how many times will the second hand pass the minute hand? Answer: 59 times. The second hand laps the minute hand 59 times every hour because both are moving in the same direction. The second hand is much faster but the minute hand is also moving forward, so the second hand does not complete a full 60 passes in exactly one hour.
A square clock has numbers on all four sides. The top row adds to 20, left column adds to 22, and bottom row adds to 18. What does the right column add to? Answer: This is a logic number puzzle. Without the exact arrangement of numbers, you use the sum property. All rows and columns must balance around a central total. If the top is 20, left is 22, and bottom is 18, the right column value can be determined by working through the grid mathematically.
If you removed every other number from a clock starting with 2, what numbers would remain? Answer: 1, 3, 5, 7, 9, 11. Starting from 1 and removing every even number, you are left with all odd numbers. The clock would only show 1, 3, 5, 7, 9, and 11. These are the six odd numbers that appear on a standard 12-hour clock face.
A clock’s hour hand is at the 4 and the minute hand is at the 8. What angle is between them? Answer: 120 degrees. The hour hand at 4 is at 120 degrees from the 12. The minute hand at 8 is at 240 degrees from the 12. The difference between 240 and 120 is 120 degrees. The hands are exactly 120 degrees apart.
If I add 100 hours to 3:00 PM today, what time and day is it? Answer: 7:00 PM four days later. Divide 100 hours by 24 to get 4 days and 4 hours remaining. Add 4 days to today and 4 hours to 3:00 PM to get 7:00 PM exactly 4 days from now.
A clock uses Roman numerals. How many individual strokes or lines are used to display all 12 numbers? Answer: 20 strokes. Count the Roman numeral lines: I=1, II=2, III=3, IV=2, V=1, VI=2, VII=3, VIII=4, IX=2, X=2, XI=3, XII=4. But traditional clock faces use IIII instead of IV, which changes the total. Using IIII, the total becomes 24 strokes on a traditional Roman numeral clock.
A sundial shows accurate time during the day. What is its biggest limitation? Answer: It only works in sunlight. A sundial depends entirely on the shadow cast by sunlight. On cloudy days, the shadow disappears and the sundial cannot tell time. At night, there is no sun at all, making the sundial completely useless during nighttime hours.
How many prime numbers appear on a standard clock face? Answer: Five prime numbers. The prime numbers between 1 and 12 are 2, 3, 5, 7, and 11. These five numbers are all divisible only by 1 and themselves. The remaining numbers on the clock, 1, 4, 6, 8, 9, 10, and 12, are not prime.
At 12:00, the hands of a clock align perfectly. How many minutes later do they align again? Answer: About 65.45 minutes later. The hands meet again approximately every 65 minutes and 27 seconds. This happens because the minute hand must travel more than a full circle to catch the slowly moving hour hand. They meet 11 times in every 12-hour period.
What is the sum of all numbers on a standard clock face? Answer: 78. Add 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12. The total is 78. This is also the formula for the sum of consecutive numbers from 1 to n, which is n times n plus 1 divided by 2. For 12, that is 12 times 13 divided by 2, which equals 78.
If a clock is reflected in a pool of still water, what happens to the direction the hands move? Answer: The hands appear to move counterclockwise. A reflection in water flips the image vertically. This mirrors the top and bottom of the clock. The hands that normally move clockwise appear to move counterclockwise in the reflection.

Wordplay and Clever Clock Riddles

What time is it when a clock is struck by lightning? Answer: Shock o’clock. This is a clever pun. “Shock” sounds like “six,” and “o’clock” is a way of saying the time. If lightning hit a clock, it would create a huge electrical shock. So the time becomes “shock o’clock,” a funny invented time.
Why do clocks always seem so stressed? Answer: Because their hands are always going around and around and they never get anywhere. A clock’s hands spin endlessly in circles. In human terms, doing something repeatedly without progress is very stressful. The clock is forever busy but forever stuck in the same place.
What do you call a clock that tells time for ghosts? Answer: A boo-koo clock, or a haunted cuckoo clock. A cuckoo clock pops out a little bird on every hour. Replace “cuckoo” with “boo” and you have a ghost version. A cuckoo that says “boo” instead of “cuckoo” would be the perfect clock for a haunted house.
I go to bed on time and wake up on time, but I am never alive. What am I? Answer: An alarm clock. An alarm clock is “put to bed” when you set it for the night and press buttons to get it ready. It “wakes up” when its alarm fires in the morning. It follows a sleep and wake schedule, but it is just a machine.
What is a clockmaker’s favorite kind of story? Answer: A timeless tale. A “timeless” story is one that stays relevant and meaningful no matter how many years pass. For a clockmaker, the word “timeless” also literally means without time, which connects to their work of managing time all day.
What do you call a nervous clock? Answer: High-strung. A clock is “strung” with its internal springs and mechanisms. “High-strung” is also a term for someone who is nervous or anxious. A clock under a lot of tension would literally be wound up tight, making it the perfect nervous character.
Why did the clock feel embarrassed? Answer: Because its hands were always pointing at people. It is rude to point at others. A clock’s hands constantly point to the numbers on its face, which is a bit like pointing at people. The clock cannot help being rude because pointing is literally its job.
What is a clock’s favorite sport? Answer: Tick-tack-toe. “Tic-tac-toe” is the well-known game played with X’s and O’s on a grid. Replace the start with “tick-tack” to match the sound a clock makes. A clock loves tick sounds, so tick-tack-toe is naturally its favorite game.
What did the big hand say to the little hand? Answer: I will be right back in an hour. The minute hand is the big hand and the hour hand is the little hand on a clock. They meet at 12 and then separate. The minute hand moves much faster and goes around the whole clock before they meet again roughly every hour.
Why do clocks never tell secrets? Answer: Because time always tells. The phrase “time will tell” means the truth always comes out eventually. A clock is all about telling time. So a clock cannot keep a secret because time itself is in the business of telling everything eventually.
What did one clock say to the other when they met at midnight? Answer: Happy new second! A play on “Happy New Year,” this pun uses the clock’s most basic unit of time. At midnight, the second changes just like the year does on New Year’s Eve. It is a clever way to celebrate both a special moment and everyday time passing.
What has a second hand but is not in a fight? Answer: A clock. In a fight, a “second hand” is a helper or backup person. But on a clock, the second hand is simply the thin hand that counts the seconds. The riddle tricks you into thinking about a conflict before revealing the simple clock answer.
Why is the clock such a good detective? Answer: Because it always has time on its hands. Detectives need time to solve cases. A clock literally has “hands” and those hands measure time. So the clock is the perfect detective, always with time right there in its hands, ready to investigate.
What do you call a watch that never stops talking? Answer: A “tick-talkative” watch. This is a made-up pun combining “tick-tock” with “talkative.” A watch that talks nonstop would be like a clock that never stops ticking. The joke imagines a watch that just cannot keep quiet, always making noise.
What is a clock’s least favorite day? Answer: Daylight saving time day. On daylight saving time, clocks are moved forward or backward by one hour. That is very disorienting for a clock. It suddenly has to skip an hour or repeat one. It is the one day a year when a clock’s routine is completely disrupted.

Challenging Expert-Level Clock Riddles

Two people are traveling in opposite directions around a circular path that takes one hour to complete. If they start at the same point at the same time, how often do they meet? Answer: Every 30 minutes. Since they are moving in opposite directions at the same speed, they approach each other at double speed. They will meet halfway around the circle every 30 minutes. This is similar to the hands of a clock meeting from opposite directions.
A clock loses exactly one second per day. How many years will it take to be 24 hours behind? Answer: Approximately 86,400 days or about 236.6 years. There are 86,400 seconds in a day. The clock loses 1 second per day. To lose an entire day of 86,400 seconds, it takes 86,400 days. Divide by 365 to get roughly 236.6 years.
If a clock’s minute hand moves 360 degrees per hour, what is its angular velocity in radians per second? Answer: Pi divided by 1,800 radians per second, or approximately 0.001745 radians per second. A full circle is 2 pi radians. The minute hand completes one full circle in 3,600 seconds. Divide 2 pi by 3,600 to get the angular velocity in radians per second.
A king has three clocks. One runs 3 minutes fast per hour. One runs 3 minutes slow per hour. One is stopped completely. After exactly 90 days, which clock has shown the correct time the most often? Answer: The stopped clock. The stopped clock shows the correct time twice a day, every day, for 180 correct time showings in 90 days. The fast clock gains 72 minutes per day and the slow clock loses 72 minutes per day. Neither will be exactly right during that 90-day window as frequently as the stopped clock.
If time is a river flowing in one direction, what would it mean to swim against the current? Answer: Traveling back in time. A river flows forward, and swimming upstream means moving against its flow. If time is a river, moving against it means going backward in time. This is theoretically impossible based on current physics, but it is the concept behind time travel.
At 12:00 noon, three clocks show the correct time. Clock A gains 2 seconds per minute. Clock B loses 1 second per minute. Clock C is accurate. When will all three next agree on the same time? Answer: After 720 minutes or 12 hours. Clock A and Clock B diverge at 3 seconds per minute relative to each other. For them to agree again, one must gain exactly 60 seconds on the other, which takes 20 minutes. But for all three to agree including accurate Clock C, you need Clock A to have gained a full 12 hours and Clock B to have lost 12 hours simultaneously, which happens at exactly 12 hours later.
A quantum clock can measure time to one attosecond. One attosecond is 10 to the power of negative 18 seconds. How many attoseconds are in one year? Answer: Approximately 3.15 times 10 to the power of 25 attoseconds. One year has about 31.5 million seconds, or 3.15 times 10 to the power of 7 seconds. Multiply by 10 to the power of 18 to convert to attoseconds and you get 3.15 times 10 to the power of 25.
Einstein’s theory of relativity says time slows down near massive objects. If a clock on a satellite runs slightly faster than one on Earth, which shows more time after one year? Answer: The satellite clock shows slightly more time. Clocks run faster when farther from gravity. Satellites experience weaker gravity than objects on Earth’s surface. GPS satellites, for example, run about 38 microseconds faster per day than ground clocks, and this must be corrected to keep GPS accurate.
A sundial and an atomic clock are both accurate at noon. By midnight, the atomic clock has recorded 43,200 seconds. How many seconds has the sundial recorded? Answer: Zero seconds. A sundial cannot measure time at night because it requires sunlight to cast a shadow. By midnight, the sun is completely below the horizon and the sundial shows nothing. Only the atomic clock continues measuring time in the dark.
If every second of your life was recorded on a clock, how many revolutions would the second hand have made by the time you reach 80 years old? Answer: Approximately 2,522,880,000 revolutions. There are about 31,536,000 seconds in a year. Multiply by 80 years to get about 2.52 billion seconds. The second hand makes one full revolution per 60 seconds, so divide by 60 to get roughly 42 million revolutions. Approximately 42,048,000 revolutions total.
A mysterious clock runs correctly for 6 hours, then backward for 3 hours, then correctly again. If it starts at 12:00, what time does it show after 18 hours? Answer: 9:00. From 12:00, it runs correctly for 6 hours to reach 6:00. Then it runs backward for 3 hours to reach 3:00. Then it runs correctly for 6 hours to reach 9:00. Then backward for 3 hours to reach 6:00. Then correctly 6 more hours to reach 12:00. Wait, with 18 total hours: correct 6 hours = 6:00, backward 3 hours = 3:00, correct 9 hours = 12:00. So at 18 hours it shows 12:00.
If you placed a clock at the center of a black hole, what would outside observers see it doing? Answer: Slowing down to a stop and freezing. Near a black hole, gravity becomes so extreme that time slows dramatically as predicted by general relativity. Outside observers would watch the clock tick more and more slowly. It would appear to freeze completely at the event horizon, never quite reaching it as seen from outside.
