What Is It Used For?
Time is base 60, which is exactly why subtracting it in your head goes wrong. This calculator also solves the overnight case: an end time earlier than the start is read as the following day, so a 22:00–06:00 shift comes out as eight hours rather than minus sixteen.
- Working out hours for a timesheet or an invoice.
- Checking the length of a night shift that crosses midnight.
- Measuring how long a meeting, a task or a journey took.
- Converting worked time into decimal hours for payroll.
- Checking rest periods between shifts.
