Enter times as 9:05, 0905 or 9. An end time earlier than the start counts as an overnight shift.

How to use

  1. Enter each shift's start time, end time and break in minutes; write times as 9:05, 0905 or 9.
  2. Choose Add row for more days.
  3. Read the hours per row and the total; decimal hours are ready to multiply by an hourly rate.

Options explained

Overnight shifts
An end time earlier than the start counts as the next day, so 22:00 to 6:00 is 8 hours.
Decimal hours
7 hours 30 minutes is 7.5 hours — what most payroll systems expect.

Frequently asked questions

How do I convert 7:45 to decimal hours?

Divide the minutes by 60 — 45 ÷ 60 = 0.75 — so 7:45 is 7.75 hours, not 7.45.

Does it work with a 12-hour clock?

Enter times in 24-hour form (1 pm = 13:00).
