Overnight shifts
A shift that starts at 10 p.m. and ends at 6 a.m. is eight hours minus break, not a negative duration. The engine treats that as a crossing of midnight.

Questions about this calculator
Does this calculate overtime at 1.5×?
No. It totals hours. Whether those hours are overtime is a wage-and-hour question this page does not answer.

Engine notes
Rounding, versioning, and omissions that sit beside the guide rather than repeating it.
- Elapsed time. Each shift is end minus start. If end is not later than start, the shift is treated as overnight and 24 hours are added.
- Breaks. Unpaid break minutes are subtracted. A break longer than the shift is rejected.
- Pay is optional. If you type an hourly rate, hours × rate is shown as a simple product. No FLSA overtime, premiums, or legal “owed” language.
