Hours Calculator

Enter a start and end time in 24-hour format (HH:MM).

Short answer

Subtract start from end to get total hours. If end is earlier than start, we assume it crosses midnight. Subtract any unpaid break minutes for paid time.

Times

Start time (24h)

End time (24h)

Unpaid break (minutes)

Fill in the fields above to see your result instantly.

How it works

Convert both times to total minutes from midnight, subtract, add 24 hours if the result is negative (meaning end is the next day), then deduct unpaid breaks.

Worked example

09:00 to 17:30 with 30 min break = 8h 30m elapsed − 0h 30m = 8h 0m paid (8.0 hours decimal).

Who should use this

•Hourly workers checking shift length
•Freelancers totalling billable time

Common mistakes

×Mixing up AM/PM — always use 24h
