Calculate working hours, breaks, overtime and overnight shifts

Work Hours Calculator

The Work Hours Calculator calculates actual working time from start and end times. Break periods can be deducted, and overtime can be calculated separately.

How to Calculate Work Hours

Enter the start and end times to calculate the time interval. Add a break period when needed to obtain the actual working duration after rest time is deducted.

Overnight Shifts

The calculator supports shifts that cross midnight, such as working from 10:00 PM to 6:00 AM the following day.

Overtime Calculation

When overtime is entered separately, the tool can calculate the overtime duration independently from regular working hours.

Common Uses

The tool is suitable for personal attendance checks, work-hour tracking, shift planning and overtime calculations. Actual payroll and overtime compensation should follow applicable employment rules and company policies.
