Work Hours Calculator

Files stay on your device · 100% private Runs in your browser

Weekly work hours from daily clock-in and clock-out times with breaks and overtime.

How it works: one row per day — clock-in, clock-out, and unpaid break minutes. Overnight shifts are handled automatically (clock-out before clock-in wraps past midnight), and the overtime line compares the week against your threshold.
Add your clock-in and clock-out times per day.
