A clock face has the numbers 1 to 12 round the edge and two hands that turn from the middle.
The short, thick hand is the hour hand. It moves slowly, going all the way round twice a day. It tells you the hour.
The long, thin hand is the minute hand. It goes all the way round once every hour. It tells you how many minutes have gone since the hour began.
Between the numbers are small marks. There are 60 of them, one for each minute. The minute hand moves from one mark to the next every minute.
hour hand: short minute hand: long
Start with the hour hand. Cover the minute hand with a finger and ask “Which number is the short hand on, or just past?” That gives the hour, even before the minutes make sense.
O’clock: the minute hand points straight up to 12. The hour hand points exactly at the hour. Half past: the minute hand points straight down to 6, half way round. The hour hand is half way between two numbers.
Quarter past: the minute hand has gone a quarter of the way round, to 3. Quarter to: it has gone three quarters of the way round, to 9. There is a quarter of an hour left before the next o’clock.
Look closely at the hour hand at half past. At half past three, the hour hand is half way between 3 and 4. It has passed 3, so it is still three-something. At quarter to four it is much nearer 4, but it still hasn’t reached it.
Each number on the clock is 5 minutes further on than the one before. So when the minute hand points at a number, count in fives from 12 to find the minutes: 1 is 5 minutes, 2 is 10, 3 is 15, and so on up to 11, which is 55.
Draw a line from 12 down to 6. On the right-hand side, we say “past” the hour that has just gone. On the left-hand side, we say “to” the hour that is coming next, and count the minutes that are left.
So when the hour hand is between 3 and 4 and the minute hand points at 8, it’s twenty to four: there are 20 minutes to go until four o’clock.
| Minute hand on | Minutes past | We say | Minute hand on | Minutes past | We say |
|---|
When the minute hand is between two numbers, count in fives to the last number it passed, then count on the small marks in ones.
In the clock here, the minute hand has passed 7 (35 minutes) and gone on 2 more marks. That’s 37 minutes past 4, written 4:37.
Because 37 is on the left-hand side, we can also say it as a “to” time. There are 60 − 37 = 23 minutes left until five o’clock, so it’s twenty-three minutes to five.
For times that aren’t in fives, we say “minutes”: eight minutes past nine, one minute to twelve. For the five-minute times we usually leave the word out: ten past nine.
Some clocks and watches use Roman numerals instead of the numbers 1 to 12. You read the time in exactly the same way: the hands, the positions and the five-minute steps don’t change.
It helps to know the three building letters: I is 1, V is 5 and X is 10. A letter after a bigger one adds on (VI is 5 + 1 = 6). A letter before a bigger one takes away (IV is 5 − 1 = 4, and IX is 10 − 1 = 9).
A clock face only goes up to 12, but a day has 24 hours. So the hour hand goes round twice: once from midnight to midday, and again from midday to midnight. To show which half of the day we mean, we write am or pm after the time.
From midnight until just before midday. Breakfast at 7:30 am is in the morning.
From midday until just before midnight. Tea at 5:30 pm is in the afternoon or evening.
12 o’clock in the middle of the day is midday or noon. 12 o’clock at night is midnight. Saying “12 noon” and “12 midnight” avoids any muddle.
The 24-hour clock doesn’t need am or pm. It keeps counting the hours after midday: 1 pm is 13:00, 2 pm is 14:00, all the way to 23:59. Then at midnight it starts again at 00:00. Times are always written with four digits, so 7:05 am is 07:05.
am times: keep the same hour and add a 0 in front if it has one digit. 9:20 am is 09:20.
pm times: add 12 to the hour. 4:45 pm is 4 + 12 = 16:45.
Except: 12:30 pm stays 12:30, and 12:30 am (just after midnight) is 00:30.
Hours 13 to 23: take away 12 and write pm. 19:10 is 19 − 12 = 7:10 pm.
Hours 01 to 11: drop the 0 and write am. 08:55 is 8:55 am.
00 is the midnight hour (00:15 is 12:15 am). 12 is the midday hour (12:15 is 12:15 pm).
| 12-hour | 24-hour | 12-hour | 24-hour |

A digital clock shows the hour, a colon, then the minutes past the hour. 4:05 means 5 minutes past 4. The minutes always have two digits, so five past four is never written 4:5.
Digital clocks only count past the hour, so 7:50 shows 50 minutes past 7. On a clock face, that’s the left-hand side: ten to eight. You can read it aloud either way: “seven fifty” or “ten to eight”.
Turning digital minutes into “to”: take the minutes away from 60, and add one to the hour. 7:50 is 60 − 50 = 10 minutes to 7 + 1 = 8.
In a leap year, February has 29 days instead of 28. Leap years usually come every four years: 2024 and 2028 are leap years.

The knuckle trick. Make two fists side by side. Touch each knuckle and each dip between them in turn, saying the months from January. Knuckle months have 31 days. Dip months have 30, apart from February. July and August are both on knuckles, where your two fists meet.
Times don’t work like ordinary numbers, because there are 60 minutes in an hour, not 100. So don’t take one time away from the other. Instead, count on from the start time to the end time in friendly jumps.
A film starts at 10:45 and ends at 11:20. How long is it?
You can do the same on a clock face: put your finger on the minute hand at the start time and count the fives as you move it round to the end time. For longer gaps, jump whole hours first: 09:10 to 12:40 is 3 hours (to 12:10), then 30 minutes.
Drag the long hand round, or click the clock and use the arrow keys: 1 minute, Shift + arrow for 5 minutes, Page Up and Page Down for an hour.
Move the minute hand and watch the hour hand creep along with it. The time is shown in words, as a 12-hour digital time and on the 24-hour clock.
Telling the time is learned mostly away from the worksheet. A few minutes of clock talk every day does more than one long lesson.
In England, the National Curriculum builds up telling the time like this:
Paraphrased from the National Curriculum for England. Schools only have to cover each key stage’s content by the end of that key stage, so the exact year can vary.
The key ideas on one A4 sheet: a labelled clock, the past and to clock, the 12-hour and 24-hour clock side by side, and the time facts to learn. Stick it on the fridge or in a maths book.
Choose a sheet to see it below, then print it.
Pick an age, then a kind of sheet. Every roll makes a fresh sheet, and the answer page shows the clocks with their hands drawn in.
