How this calculator works

Core formula

duration = end time - start time, with overnight rollover if needed

Times are converted into seconds, and if the end time is earlier than the start time the calculator assumes the period crossed midnight.

  • The result is broken into hours, minutes, and seconds.
  • Total minutes and total seconds are useful for scheduling and payroll math.
