Choose the end day explicitly
The calculator does not silently assume that an earlier clock time means tomorrow. Pick the following day for an overnight shift.

YOUR RESULT
8 hours 0 minutes
Example: 22:00 to 06:30 the following day spans 510 minutes. Subtract a 30-minute unpaid break to get 480 minutes, or 8.00 decimal hours.
Subtract only the break you intend to exclude
Enter the total unpaid break minutes from your own record. Whether a break should be paid depends on the applicable arrangement; this calculator only subtracts the number entered.
Keep decimal hours separate
7 hours 30 minutes is 7.50 hours, not 7.30. Decimal hours divide the remaining minutes by 60.

Before you use the result
Does this handle daylight-saving clock changes?
No. This is a clock-time calculation assuming a normal 24-hour day. A clock change or time-zone change needs a separate elapsed-time check.
Can a shift last more than 24 hours?
This worksheet accepts intervals from zero to 24 hours. Split longer periods into documented intervals.
Are the results sent to my employer?
No. The tool runs in this page and sends no records or messages.
