How it works
The calculator iterates day-by-day from the start date to the end date and counts days that are: (1) not a selected weekend day, and (2) not in your holiday list.
Examples
- 2026-03-02 to 2026-03-06 with Sat/Sun weekends → 5 work days (inclusive)
- Add holiday 2026-03-04 → 4 work days
- Switch weekend to Fri/Sat → adapts for different regions
