Overnight shifts
When the end time is earlier than the start, it is treated as the following day so evening-to-morning work can be calculated.

The practical guide
Turn a start and end time into net working hours.
The calculator finds elapsed time, handles an end time after midnight, subtracts an unpaid break, and presents hours in clock and decimal form.
Subtract unpaid breaks
Break minutes are removed from elapsed time and cannot exceed the full shift duration.
Decimal hours and pay
Decimal hours simplify timesheets and optional pay estimates. Actual payroll may use different rounding, overtime, tax, and break rules.
