8pm to 8am is how many hours?
8:00 PM to 8:00 AM the next day is 12 hours (12.00 decimal hours). Take off any unpaid break to get the hours you are actually paid for.
The quick answer
20:00 to 08:00 (next day) = 720 minutes 720 ÷ 60 = 12.00 hours = 12h 00m Minus a 30-minute unpaid break = 11h 30m paid
This shift crosses midnight. Split it at 12:00 AM if you are working it out by hand: 8:00 PM to midnight, plus midnight to 8:00 AM.
8pm to 8am after an unpaid break
| Unpaid break | Hours worked | Decimal hours |
|---|---|---|
| None | 12h 00m | 12.00 |
| 15 minutes | 11h 45m | 11.75 |
| 30 minutes | 11h 30m | 11.50 |
| 45 minutes | 11h 15m | 11.25 |
| 60 minutes | 11h 00m | 11.00 |
Deduct a break only when it is unpaid, and only once — a common payroll error is subtracting a break that the clock system has already excluded.
Across a week

Weeks over 40 paid hours usually attract overtime. Split regular and overtime pay in the overtime pay calculator, or total a full timesheet in the time card calculator.
