10 PM to 6 AM calculation
From 10 PM to midnight is 2 hours. From midnight to 6 AM is 6 hours.
2 hours + 6 hours = 8 hours
What if there is an unpaid break?
| Unpaid break | Worked time | Decimal |
|---|---|---|
| None | 8h 00m | 8.00 |
| 30 min | 7h 30m | 7.50 |
| 45 min | 7h 15m | 7.25 |
| 60 min | 7h 00m | 7.00 |
Why overnight shifts cause mistakes
If you simply subtract 22:00 from 06:00, the end time appears smaller. The fix is to treat 6 AM as belonging to the next day, or to split the shift at midnight.
