Know the numbers

How to use this calculator

Choose clock-out or break return. For clock-out, enter the shift start, the paid duration you want to complete, and all unpaid break minutes. For break return, enter the time your break starts and its length.

A worked example

Start at 8:15 AM, work 8 paid hours, and take 30 unpaid minutes: clock out at 4:45 PM. A 30-minute break starting at 11:50 PM ends at 12:20 AM the next day.

The calculation

Clock-out = start + paid target + unpaid breaks. Break return = break start + break duration.

Before you use the result

This is schedule arithmetic, not permission to leave work or a recommendation about break entitlement. The output uses wall-clock time and states date rollover.
