🕓 8-Hour Shift Calculator
Find exactly when your shift ends — including overnight shifts.
How This Is Calculated
Shift End Time = Start Time + Shift Length + Unpaid Break Time. Breaks extend your total time on-site without counting as paid work — an 8-hour shift with a 30-minute break means 8.5 hours between clock-in and clock-out. This calculator automatically detects when a shift crosses midnight into the next day.
Guide: understanding your result
- Shift end time = start time + scheduled working hours + unpaid break time.
- Under the federal FLSA, short breaks (usually 5–20 minutes) are paid working time, while bona fide meal periods of 30 minutes or more can be unpaid if you are fully relieved of duty.
- Federal law does not require meal or rest breaks for adults, but many states do; check your state's rules.
Worked example
An 8-hour shift starting at 7:30 AM with a 30-minute unpaid lunch ends at 4:00 PM. Two paid 15-minute breaks do not move the end time.
Common mistakes to avoid
- Adding paid rest breaks to the shift length.
- Forgetting overnight shifts cross midnight — use 24-hour time to avoid AM/PM errors.
Frequently asked questions
When is overtime due?
Non-exempt employees covered by the FLSA must receive at least 1.5 times their regular rate for hours over 40 in a workweek; some states also have daily overtime rules.
