Business Day Calculator
Use this free business day calculator to add business days to a date or count working days between two dates.
How the business day calculator works
Business days are Monday to Friday. The calculator skips Saturdays and Sundays; public holidays are not removed.
Frequently asked questions
Does it exclude holidays?
No. Only weekends are skipped, so subtract any public holidays that fall in your range.
Are public holidays excluded?
This calculator counts business weekdays based on its date logic and does not apply a public-holiday calendar. A holiday that falls on a weekday may still be counted.
Does the start date count as a business day?
The result depends on whether you are adding business days or counting weekdays between dates. Check the calculator’s selected operation and displayed date range.
