Business Days Calculator
Count working days between dates, with a custom work week.
Counts each day from the start date up to (not including) the end date. Public holidays vary by country — add them by unchecking that weekday only as an approximation, or subtract manually.
How to use the Business Days tool

- Adjust any slider or type an exact number — the answer updates as you go.
- Copy the result and close the tab. Nothing you entered was sent anywhere.
About the Business Days tool
Pick two dates and choose which weekdays count as working; the calculator returns business days, excluded days and the total calendar span.
Notice periods, SLA windows and delivery estimates usually run in business days — but public holidays are country-specific, so subtract those separately for legal precision.
