How It Works
Formula
Gross minutes = end - start (add 1440 if crossing midnight)
Net minutes = gross - break minutes
Total hours = net minutes / 60
Overtime = max(0, total - overtime threshold)Clock times are converted to minutes, break time is subtracted, and hours are split by the overtime threshold.
Calculation note: values are processed in the order shown above, using the current input units.
