Output and limitations
Count working days between dates, excluding your chosen weekends and holiday list.
Both start and end dates are included. The end date must not precede the start. Use YYYY-MM-DD dates. For a custom weekend, enter seven digits from Monday to Sunday: 1 excludes that weekday and 0 includes it. Holiday duplicates count once; holidays on weekends are not subtracted twice. Up to 3,660 calendar days. National holidays, employment rules and half-days are not inferred.
