How do you calculate an overnight shift?
When the end time is earlier than the start time, add 24 hours to the end before subtracting the start. Subtract any unpaid breaks only after finding the full overnight duration.
Breaks are subtracted only after the overnight elapsed duration is established.
Overnight elapsed minutes = end minutes + 1,440 − start minutes.
Worked example
A 22:00 to 06:00 shift lasts 8 hours; with a 30-minute unpaid break, the net time is 7 hours 30 minutes.
Important cases
- The calculator crosses midnight when the end time is earlier.
- A 23:59 to 00:00 shift lasts one minute.
