Time - Grade 2 Math Worksheets - Free Printable

Let’s go through each time conversion step by step.

We are converting from 12-hour clock (with am/pm) to 24-hour clock.

Rules:
- For am times:
→ If it’s 12:00am, that becomes 00:00.
→ Otherwise, just remove “am” and keep the same numbers (but add a leading zero if needed for single-digit hours).

- For pm times:
→ If it’s 12:00pm, that stays 12:00.
→ Otherwise, add 12 to the hour part, then remove “pm”.

Let’s solve each one:

---

1. 8:15pm
→ pm, not 12 → 8 + 12 = 20 → 20:15

2. 7:50am
→ am, not 12 → keep as is → 07:50 (add leading zero)

3. 4:45pm
→ pm, not 12 → 4 + 12 = 16 → 16:45

4. 3:30am
→ am, not 12 → 03:30

5. 2:55pm
→ pm, not 12 → 2 + 12 = 14 → 14:55

6. 9:30am
→ am, not 12 → 09:30

7. 6:00pm
→ pm, not 12 → 6 + 12 = 18 → 18:00

8. 5:45am
→ am, not 12 → 05:45

9. 1:00pm
→ pm, not 12 → 1 + 12 = 13 → 13:00

10. 3:00am
→ am, not 12 → 03:00

---

Now the second column:

11. 4:15pm
→ pm, not 12 → 4 + 12 = 16 → 16:15

12. 9:50am
→ am, not 12 → 09:50

13. 12:35pm
→ pm, and it’s 12 → stays 12:35

14. 10:40am
→ am, not 12 → 10:40

15. 2:00pm
→ pm, not 12 → 2 + 12 = 14 → 14:00

16. 7:20am
→ am, not 12 → 07:20

17. 3:45pm
→ pm, not 12 → 3 + 12 = 15 → 15:45

18. 10:55am
→ am, not 12 → 10:55

19. 11:00pm
→ pm, not 12 → 11 + 12 = 23 → 23:00

20. 9:25am
→ am, not 12 → 09:25
