How to calculate hours between two times

  1. Enter the start time and choose AM or PM.
  2. Enter the end time. If it is earlier than the start, the calculator assumes the next day.
  3. Enter any unpaid break in minutes. The result shows hours:minutes, decimal hours and total minutes.
Formula
Duration = End − Start (+ 24 h if End is earlier than Start) − Break

Worked example

A night shift from 10:00 PM to 6:30 AM. The end is earlier than the start, so add 24 hours: 6:30 + 24:00 − 22:00 = 8:30. Take off a 30-minute unpaid break and the shift is 8:00, or 8.00 hours.
