Time Duration Calculator

Find out how much time is between a start and end time — shown in hours and minutes and as a decimal (handy for timesheets and pay). Subtract a break if you need to, and it handles shifts that run past midnight. Updates as you type.

Start time End time Break (minutes)

End time is the next day (overnight shift)

Tips

Decimal hours are what most payroll systems use: 8 hours 30 minutes = 8.5 hours.
Overnight shifts: tick the box when the end time is earlier in the clock than the start (e.g. 22:00 → 06:00).
Breaks are subtracted from the total, so you get paid (or billed) hours.
