Shift Calculator
About the Shift Calculator
A shift calculator is the practical bridge between a clock and a timesheet. Workers need to know how many hours they actually worked, supervisors need to verify breaks, and payroll teams need decimal values that match pay systems. This page handles start time, end time, break deductions, and overnight shifts so a late closing shift or early warehouse start is not miscounted. Enter the clock-in and clock-out exactly as recorded, then separate unpaid breaks from paid time.
How to use it
- Open the Shift Calculator and confirm the specific situation you are planning before entering values.
- Add clock-in, clock-out, unpaid breaks, paid breaks, and overnight status, using the same source calendar or record for every field.
- Check the Shift Calculator preview for conflicts, missing context, or assumptions that would change the answer.
- Use the result as net shift duration with decimal-hour support, then compare it with any official schedule or policy.
- Copy the Shift Calculator outcome into your planner, message, or work record and recalculate when details change.
Good to know
Calculators and planners run in this browser. Sleep-cycle times are a rule of thumb, not a medical diagnosis. Check the result against the time you actually need to be awake.
