Business days calculator
Count a date range, calculate a business-day deadline, or compare working dates across two countries.
Choose an end date to load the applicable public-holiday datasets.
Use cases for business-day planning
Count SLA windows, calculate invoice or contract deadlines, and find cross-border operating dates with explicit weekend and holiday rules.
Project planning
Measure available working time or calculate a milestone deadline.
Cross-border teams
Use separate weekend rules and find dates when both countries operate.
Payment and logistics
Calculate processing dates while documenting every skipped closure.
How the count works
Weekends follow the rule you pick (Saturday–Sunday or Friday–Saturday). Weekday nationwide public holidays in the selected country dataset are skipped. State, school, and employer closures are not inferred.
If holiday data cannot be fetched, the tool refuses to invent a zero-holiday calendar. Compare two countries only when you need overlapping operating days, not when you need a legal day-off ruling.
For a named holiday’s exact date, open that country’s holiday page. This calculator answers “how many working days,” not “is Thanksgiving a federal holiday.”
