Using Clocks
Learn how to read analogue and digital clocks.

Clock hands and minutes
The short hand shows the hour
The long hand shows the minutes
There are minutes in one full hour
Each number on the clock stands for minutes
1$$ means $$5 minutes past
2$$ means $$10 minutes past
and so on

O'clock and half past
If the long hand points to , the time is o'clock
If the long hand points to , the time is half past
Half of 60$$ minutes is $$30 minutes
So half past means minutes past the hour

Quarter past and quarter to
A quarter of 60$$ minutes is $$15 minutes
"Quarter past" means minutes after the hour
- The long hand points to
"Quarter to" means minutes before the next hour
- The long hand points to

Digital times
Digital times show hours and minutes
The number before the colon shows the hour
The number after the colon shows the minutes
