Master both clock formats

By Grade 5, students convert confidently between the 12-hour and 24-hour clocks to the minute — a skill they’ll use for timetables, travel and computing. These worksheets shuffle both directions and all the minutes, so every sheet is a fresh challenge.

23:15 → ?

The hour is 23, which is more than 12 — subtract 12: 23 − 12 = 11, and it’s PM.
Keep the minutes: 15.
Answer: 11:15 PM.

How to use these worksheets

For 24-hour times of 13:00 or later, subtract 12 and add PM.
For AM/PM times, add 12 to PM hours (except 12 PM) to get 24-hour time.
