Hours Calculator

Calculate hours between times, add or subtract hours, and convert hours to other time units.

Result

Fill in the fields above, then press Calculate.

An hours calculator totals work hours across multiple shifts, subtracts break time, and optionally computes earnings from an hourly rate.

Enter start and end times for each shift in 24-hour format (HH:MM). Add break time in minutes. Optionally enter your hourly rate to calculate earnings. Up to 3 shifts are supported for split-shift schedules.

Examples

Standard 9-to-5 with lunch break

Start: 09:00, End: 17:00, Break: 30 min. Total = 8h 0m - 0h 30m = 7h 30m (7.50 hours).

Overnight shift

Start: 22:00, End: 06:00, Break: 15 min. Total = 8h 0m - 0h 15m = 7h 45m (7.75 hours).

Frequently Asked Questions

How are overnight shifts handled?
If your end time is earlier than your start time, the calculator assumes the shift crosses midnight and adds 24 hours to the calculation.
Can I calculate pay with overtime?
This calculator computes straight-time earnings. For overtime tracking with weekly totals, use the Time Card Calculator instead.
