# Telling time (labeled clock)

Learn about how to tell time using an analog clock. It covers identifying the hour and minute hands, understanding the concept of hours and minutes, and reading the clock to determine the time. See multiple examples to demonstrate the process of telling time. Created by Sal Khan.

- Why do we have different time lines all over the world?(27 votes)
- The world is round, which means the sun cannot hit all points of the Earth at the same time. When it might be day for you, it is night for somebody on the other side of the Earth, because the sun is unable to reach that point on the planet. Times are adjusted according to where the sun is currently able to light the Earth.(24 votes)

- Why does the 12 on the clock mean12:00and zero minutes?(11 votes)
- Because the12:00shows that the 60 minute cycle is complete and it begins again(15 votes)

- In parallel universe, could there be 100 minutes in an hour instead of 60?(12 votes)
- Certainly, and we could have it in our universe too. For example the french attempted that with French Revolutionary Time.

Copied from Wikipedia: " French Revolutionary Time divided the day into 10 decimal hours, each decimal hour into 100 decimal minutes and each decimal minute into 100 decimal seconds"

They were not the only ones. There have been many such examples throughout history.(17 votes)

- Why does the analog clock have hands but digital clock have no hands.(10 votes)
- Analog clocks use moving hands pointing at fixed numbers to represent hours and minutes in a 12-hour format. Digital clocks show minutes and hours as moving numbers and so no hands are needed to point the numbers out. Digital clocks can also show time in 24-hour format.(13 votes)

- Why do you have to put like for an example2:05why do you need to put a 0 before the five? Could you just do2:50?(8 votes)
- If you put2:50, you mean:
*two hours and FIFTY minutes*

If you put2:05, you mean:*two hours and FIVE minutes*

50 isn't the same thing of 5, so you couldn't(16 votes)

- Is there a reason for the one that goes around faster then the other ones?(7 votes)
- The smaller one counts the hours and there are 24 hours in a day, 12 hours around a clock. So the small hand goes around the clock only two times each day. The bigger hand counts the minutes. There are 60 minutes in each hour. The big hand goes around the clock once each hour, so it goes around the clock 24 times each day. If you have a clock with a second hand, then it can actually become fun to watch the clock. There are 60 seconds in each minute. The second hand can be long, but it will be very skinny. It will move constantly. I love to sit and watch the seconds go by! It will go around the clock 60 times every hour and 1,440 times a day!(3 votes)

- How do you tell time on a sundial?(9 votes)
- it's like a normal clock face but there is a stick in the middle so that a shadow is cast by the sun as the stick works as an hour hand(8 votes)

- Why is midnight called midnight if its the begging of the day?(7 votes)
- Because it happens toward the middle of the night(11 votes)

- What is military time, and why does it have no A.M. or P.M.?(6 votes)
- Millitary time is a another way to write time. And it does not have a.m. or p.m. because it measures what hour it is of the day. For example, 1:oo p.m. is the 13th hour of the day, so in military time they write as13:00. And if the time was2:15p.m , you would write it as14:15in military time.(6 votes)

- How many days are in a leap year and does it affect April 28?(4 votes)
- There are 366 days in a leap year, and if it is a leap year, the extra day occurs on February 29th.(5 votes)

## Video transcript

We are asked, what time is it? So we first want to look at the
hour hand, which is a shorter hand here and see
where it is pointing. And it is pointing
right at seven. So we've just crossed
the seventh hour. So the hour is seven. And then we look at the minute
hand, which is the longer hand. And this minute hand is pointing
straight up, right at the 12. So this means the
12, when you think of minutes, that's zero
minutes past the hour. And then each number
represents five more minutes. So this is right at 7:00. Let's check our answer. Let's do a few more of these. Where is the hour hand? So this hour hand,
you might say, hey, this looks closer to
eight than it is to seven, but the key is to realize
that it has passed seven and it hasn't gotten
quite to eight yet. So we're still in
the seventh hour. So the hour is seven. Notice, these hands go
in a clockwise direction. So just past seven hasn't
gotten to eight yet. So the hour is seven. And when we want to think
about the minutes, remember, we start at the top
of the clock, that's zero minutes past the hour. And then we can count
by fives all the way to where the minute hand is. So 0, 5, 10, 15, 20,
25, 30, 35, 40, 45. We're 45 minutes past the hour. So it's 7:45. Let's do a couple more. So where's the hour hand? Well it's between
the one and the two, but the key is to realize
that it's going clockwise, it's passed the one, and
it's about to get to two. So it's still in the first hour. So the hour is still one. And then the minutes, we just
have to count from 0 by fives. So 0, 5, 10, 15, 20,
25, 30, 35, 40, 45. It's 1:45 PM. Let's do one more. So here, once again, hour
hand is between 1 and 2. So it's past one, it
hasn't gotten to two yet. So we're still in
the first hour. And then the minutes,
well, we start at 12. That's zero minutes
past the hour. 0, 5, 10, 15. So it is 1:15. Let's do even one more. So this one the hour
hand is exactly at two. And the minute hand
is exactly at 12. So that means we're zero
minutes past the hour. So it's zero minutes
past the hour.
