Analogue and digital
- On an analogue clock the short hand shows the hour and the long hand the minutes. For the long hand, each number is 5 minutes.
- A digital clock shows the time in numbers: 07:45.
- Quarter past 3 = 3:15; half past 3 = 3:30; quarter to 4 = 3:45.
- In 24-hour time, 12:00 is noon and 00:00 is midnight.
In Afrikaans half vier means 3:30 (half way to four). In English we say half past three.
Elapsed time
Count on in jumps: from 08:40 to 11:15 → 08:40 to 09:00 (20 min) → 09:00 to 11:00 (2 h) → 11:00 to 11:15 (15 min) = 2 h 35 min.

- A stopwatch measures seconds: a winner runs 100 m in 14,2 seconds.
- Read a calendar: from 25 March to 4 April is 10 days.
- Long periods: 1 decade = 10 years; 1 century = 100 years. From 1652 to 2026 is 374 years: almost 4 centuries.
- Long ago people measured time with a sundial, a water clock, an hourglass and the phases of the moon.
Remember this and test yourself
- Short hand = hour; long hand = minutes.
- For the long hand, each number on the clock is 5 minutes.
- Elapsed time: count on to the next whole hour.
- 60 min = 1 hour; 24 hours = 1 day.
- A leap year has 366 days.
