How it works
The shift length is the time between the start and the end, using “Ends next day” for overnight shifts. The unpaid break is then subtracted.
A break longer than the shift is an error. A break equal to the shift gives 0h 00m worked.
shift length = end − start (+ 24h with Ends next day)
worked time = shift length − unpaid breakNote. This calculator totals one shift. For several days, overtime estimates or gross pay, use the Time Card Calculator.
Limitation. This calculator uses nominal clock time and does not adjust for daylight saving changes.
Frequently asked questions
Should I include paid breaks?
No. Only enter unpaid breaks. Paid breaks count as time worked.
How do I calculate an overnight shift?
Enter the start and end times and turn on “Ends next day”. For example, 11:00 PM to 7:00 AM with a 30-minute break is 7h 30m worked.
Can the break be as long as the shift?
Yes. The worked time is then 0h 00m. A break longer than the shift is an error.
How is this different from the Time Card Calculator?
Work Hours totals one shift. The Time Card Calculator totals 7 or 14 days, with estimated overtime and optional gross pay.
