Method and scope

Working time equals the elapsed attendance interval minus break minutes. Enter break duration in minutes, even when start and end use clock times.

The result is time after the entered breaks, not automatically paid time. A break longer than attendance is invalid.

This tool does not classify overtime, statutory working hours or pay eligibility. Taiwan wage and overtime questions require the appropriate employment rules.
