About the Hours Between Times Calculator

The ByteTools Hours Between Times Calculator works out how much time separates a start time and an end time. Enter a clock-in and clock-out and it returns the gap in hours and minutes, as a decimal number of hours for payroll, and in total minutes — with an optional break deduction for accurate timesheets.

It correctly handles shifts that cross midnight: a 22:00 start and 06:00 end is counted as eight hours, not a negative number. Subtract unpaid break minutes and you get the exact payable time, making it ideal for hourly workers, managers, freelancers and anyone reconciling hours worked.

Every calculation runs locally in your browser with JavaScript. No times are uploaded, so your timesheet data stays entirely on your device.

Frequently asked questions

How do I calculate hours between two times?

Enter the start and end clock times and the tool converts both to minutes past midnight, subtracts them, and shows the difference in hours and minutes. If the end time is earlier than the start, it assumes the shift crossed midnight.

How does it handle a shift that goes past midnight?

When the end time is before the start time — for example 22:30 to 06:15 — the calculator adds 24 hours to the end, so the result is a correct positive duration of seven hours and 45 minutes rather than a negative number.

How do I subtract a lunch break?

Enter the unpaid break length in the break-minutes field. The tool deducts it from the raw time between clock-in and clock-out, giving the exact payable hours and minutes for the shift.

What are decimal hours and why are they useful?

Decimal hours express minutes as a fraction of an hour — 7 hours 30 minutes becomes 7.5. Payroll systems multiply decimal hours by an hourly rate, so this format saves you converting minutes by hand.

Does this calculate a duration or a time of day?

It calculates a duration — the length of time between two clock readings. The inputs are times of day, but the output is how long the shift lasted, ready for timesheets and pay calculations.
