How to calculate hours worked
Subtract the start time from the end time, then subtract unpaid break minutes. If you work the same schedule on multiple days, multiply the daily worked time by the number of days.
Example
9:00 AM to 5:30 PM is 8.5 elapsed hours. Subtract a 30-minute unpaid lunch and the worked time is 8.0 hours.
Overnight shifts
A shift such as 10:00 PM to 6:00 AM crosses midnight. The calculator automatically treats the end time as the following day.
