A clock has two hands: the short hour hand and the long minute hand.
When the long hand points to 12, it is exactly o’clock — read the hour from the short hand.
When the long hand points to 6, it is half past the hour — 30 minutes after.

Worked example. The short hand is on 3 and the long hand on 12. What time is it?

Long hand on 12 means o’clock, and the short hand on 3 gives 3 o’clock.

A week has 7 days: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday.
A year has 12 months, from January to December.
A calendar shows the days and dates of each month, so we can find birthdays and festivals.

Worked example. If today is Monday, what day comes after 2 days?

Monday → Tuesday (1) → Wednesday (2). So it will be Wednesday.

One hour is 60 minutes; half an hour is 30 minutes.
Short things take seconds (a clap), some take minutes (brushing teeth), some take hours or days (a journey, a holiday).
To find how long, count from the start time to the end time.

Worked example. A class starts at 8 o’clock and ends at 9 o’clock. How long is it?

From 8 to 9 o’clock is 1 hour.

Common mix-up: the long hand shows minutes, the short hand shows the hour. Reading the wrong hand gives the wrong time.

Where you’ll meet it

Knowing the time helps you wake up, reach school and watch your favourite show on time.

A calendar helps you count the days left until your birthday and mark the date.

Trains and buses run on a timetable, so reading clocks helps you reach the station on time.
