What this tool does
Count both boundary dates, separate weekends, and subtract only holidays or closures that fall on Monday through Friday.
How to use it
- Choose the start and end dates.
- Enter the number of weekday holidays or closures in that period.
- Review calendar days, weekend days and final workdays.
Formula and method
Count every Monday through Friday from the start date through the end date. Workdays = weekdays − entered weekday holidays.
Example
September 1–30, 2026 contains 30 calendar days and 22 weekdays. With one entered weekday holiday, the result is 21 workdays.
Useful for
- Estimating project lead time
- Planning a weekday workload
- Checking processing windows
Limits and notes
It does not look up national or company holidays. The weekend is fixed to Saturday and Sunday, so other workweeks need a separate schedule.
