Context & Reference

Calculators are most useful when their assumptions are clear. Review these details to better understand the logic behind the results.

The calculator finds elapsed time between two clock times and subtracts the break in whole minutes.

Enter start and end times, add a break in minutes, and review gross and net working hours.

Net hours are the time available after the break; an earlier end time is treated as an overnight shift.

A 09:00 to 17:00 shift with a 30-minute break contains 7 hours and 30 minutes of net working time.

Times use a 24-hour clock. If the end time is earlier than the start time, an overnight shift is assumed.
