What is a Work Hours Calculator?
A work hours calculator helps you calculate how long you worked in a shift after subtracting unpaid break time. It is useful for daily attendance, timesheets, freelance billing and simple payroll estimates.
Formula used
Gross duration = end time - start time. Net work time = gross duration - break minutes. Decimal hours = net work minutes / 60.
Overnight shifts
If the end time is earlier than the start time, the calculator treats it as an overnight shift and adds 24 hours to the end time before calculating duration.
