Shift Length Calculator
Calculate shift length from start time, end time, and unpaid break minutes, including overnight shifts.
Formula
Shift Length = End Time - Start Time - Break Time Complete example
A 10:00 PM to 6:30 AM shift with a 30 minute break equals 8.0 paid hours.
When to use this calculator
- Check scheduled shift length.
- Calculate overnight work hours.
- Verify time clock entries before payroll.
How to interpret the results
The result is paid shift length after break minutes. Overnight shifts are handled by rolling the end time into the next day.
Common mistakes
- Treating overnight end time as same-day time.
- Entering paid breaks as unpaid break minutes.
- Forgetting to subtract meal breaks.
