How it works

The tool steps day by day from the start to the end date (in UTC, so daylight saving never miscounts). Saturdays and Sundays are counted as weekend days; every other day is a working day — unless its date appears in your holiday list and it falls on a weekday, in which case it’s subtracted too. Toggle whether the end date itself is included. Everything runs locally.
