9pm to 7am is how many hours?
9:00 PM to 7:00 AM the next day is 10 hours (10.00 decimal hours). Take off any unpaid break to get the hours you are actually paid for.
The quick answer
21:00 to 07:00 (next day) = 600 minutes 600 ÷ 60 = 10.00 hours = 10h 00m Minus a 30-minute unpaid break = 9h 30m paid
This shift crosses midnight. Split it at 12:00 AM if you are working it out by hand: 9:00 PM to midnight, plus midnight to 7:00 AM.
9pm to 7am after an unpaid break
| Unpaid break | Hours worked | Decimal hours |
|---|---|---|
| None | 10h 00m | 10.00 |
| 15 minutes | 9h 45m | 9.75 |
| 30 minutes | 9h 30m | 9.50 |
| 45 minutes | 9h 15m | 9.25 |
| 60 minutes | 9h 00m | 9.00 |
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
| Days a week | No break | With 30-min break |
|---|---|---|
| 3 | 30h 00m | 28h 30m |

| 5 | 50h 00m | 47h 30m |
| 6 | 60h 00m | 57h 00m |
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.

Frequently asked questions
Is 9pm to 7am 10 hours exactly?
Yes — 9:00 PM to 7:00 AM the next day is 600 minutes, which is 10 hours or 10.00 decimal hours. That is the elapsed time; unpaid breaks come off separately.
How many hours is 9pm to 7am with a 30-minute lunch?
9 hours 30 minutes, or 9.50 decimal hours. Subtract the break only if it is unpaid — see the lunch break guide if you are unsure.
Does this shift cross midnight?
Yes. 9:00 PM is on one day and 7:00 AM is on the next, so the elapsed time is measured across midnight. In a timesheet, record it on the day the shift started and mark it as ending the next day.
What is 9pm to 7am five days a week?
50 hours of elapsed time, or 47 hours 30 minutes once a 30-minute unpaid break is taken off each day. Totals should be summed from minutes, not from rounded daily decimals.
