Quick answer
How do you calculate the time between two times?
Convert both times to minutes (hours × 60 + minutes), then subtract the start time from the end time. If the result is negative, the end time falls on the next day, so add 24 hours, or 1,440 minutes. Example: from 09:00 to 17:30, you get 1,050 - 540 = 510 minutes, which is 8h30.
| Start | End | Duration | In minutes |
|---|---|---|---|
| 09:00 | 17:30 | 8h30 | 510 |
| 08:15 | 12:45 | 4h30 | 270 |
| 13:30 | 18:00 | 4h30 | 270 |
| 09:45 | 17:15 | 7h30 | 450 |
| 22:00 | 06:00 (next day) | 8h00 | 480 |
| 07:50 | 16:20 | 8h30 | 510 |
