Quick answer

How do I calculate time worked between two times?

Convert both times to minutes, subtract start from end, subtract any break, then convert back to hours and minutes.

How it works

From inputs to result in four steps

A quick walkthrough of what this calculator does behind the scenes.

  1. 1

    End minutes − Start minutes = total minutes worked

  2. 2

    Subtract any break time

  3. 3

    Convert back to hours and minutes

Formula

The math behind the number

No black box — here's exactly how the result is computed.

Formula

Start total = Start hour × 60 + Start minute
End total   = End hour × 60 + End minute
Worked min  = End total − Start total − Break minutes
Worked hrs  = Worked min / 60
