Business days calculator
Count the working weekdays between two dates — weekends excluded.
How the business days calculator works
A business day is any Monday-to-Friday date. Enter a start and end date and the calculator checks every date in the range, counting the weekdays and skipping Saturdays and Sundays — useful for delivery estimates, notice periods, and project deadlines.
Both the start and end dates are included when they fall on weekdays. Public holidays are not subtracted, because they differ by country and region — knock your local holidays off the result yourself.
business days = weekdays (Mon–Fri) in the range, inclusive
Business days calculator FAQ
Are public holidays excluded?
No. Holidays vary by country and region, so the tool counts every Monday-to-Friday date. Subtract your local public holidays from the result for a fully accurate figure.
Are the start and end dates themselves counted?
Yes — when the start or end date falls on a weekday, it is included in the count.
How is the count actually done?
The calculator walks through each calendar date in your range and counts the ones that fall on Monday through Friday. Weekends are skipped.
Can I use this for a “10 business days from today” deadline?
Yes. Pick today as the start date, try an end date, and adjust until the business-day count matches the deadline you need.
