About this calculator

Use this for a shift or a timesheet. Elapsed minutes = end clock − start clock. If the end is earlier than the start, a night shift is assumed and 24 hours are added. 09:00 to 17:30 is 8.5 hours (510 minutes). Seconds are ignored. Hours are 0–23; minutes are 0–59.

Start hour / Start minute: Start clock time.

End hour / End minute: End clock time.

Minutes / Hours: Elapsed duration.
