Lesson overview

Time

An analogue clock and a digital 12-hour clock can show the same time in different ways. Reading the minute hand first and then the hour hand helps match the two forms correctly.

Match analogue and digital

An analogue clock showing quarter past 3 matches the digital time 3:15.

Digital3:15

The minute hand shows the minutes and the hour hand shows the hour.

Half past

When the minute hand is at 6, the time is half past the hour.

7:30

Half past means 30 minutes after the hour.

Quarter to

Quarter to 5 is the same as 4:45.

Wordsquarter to 5
Digital4:45

Quarter to means 15 minutes before the next hour.

Worked example

Write the digital 12-hour time for an analogue clock showing quarter to 6.

123456789101112
quarter to 6
  1. Quarter to means 15 minutes before the next hour.
  2. The next hour is 6, so the current hour is 5.
  3. 15 minutes before 6 o'clock is 5:45.
  4. So the digital time is 5:45.
