Dates and operations
Count working days between two dates and optionally exclude weekends plus selected holiday calendars for a more practical planning baseline.
Calculator
Pick a date range, decide whether weekends should count, and add a country holiday calendar when you need a tighter estimate.
Method
The logic iterates date by date from start to end, tracks total days, flags weekend dates, and checks holiday matches from built-in country rules.
Business-day output is the remaining set after exclusions.
Limitations: holiday rules are simplified and may not include all regional observances, one-off decrees, or company-specific non-working days.
