How to use this Hours Calculator

Enter a start and end time, then subtract any unpaid break minutes. By default, an end time earlier than the start is treated as the next day so overnight shifts work naturally. Optional rounding applies to the clock-in and clock-out times before the duration is calculated. Use the presets for common schedules and copy the result when you need it elsewhere.
