How to work out hours ago
- 1
Use the 24-hour clock
Write the time now in 24-hour form. 3:00 AM is 03:00, and 7:30 PM is 19:30.
- 2
Subtract the hours
19:30 − 5 hours = 14:30, which is 2:30 PM.

Below zero? Add 24
If you get a negative number, add 24 and go back one day. 03:00 − 7 = −4, so −4 + 24 = 20:00 yesterday.
