How to count business days
- Enter a start and end date to count the business days between them, or
- Enter a start date and a number of business days to add (or subtract) to get a result date.
How this works
Saturdays and Sundays are excluded from the count. Public holidays are not automatically excluded, since holiday calendars vary by country and region.
Common use cases
- Calculate a project deadline that falls a set number of business days away
- Count how many working days remain until a due date
- Check an SLA or shipping estimate that's measured in business days
