About This Tool
Use the business days calculator to count Monday through Friday weekdays in a date range, optionally subtract holidays, and review separate totals for weekends and all counted days.
How To Use It

- Choose whether to include each endpoint.
- Enter any holidays to exclude as YYYY-MM-DD dates.
- Review adjusted business days, weekend days, holiday exclusions, and total counted days.
Examples
Project planning window
Count the weekdays between a kickoff date and a deadline to estimate how many standard workdays are available.
Service-level timing
Estimate whether a response window spans two, five, or ten standard business days.
Useful Notes
Holiday handling
Business days are calculated as Monday through Friday. Enter holidays manually when your business calendar excludes them.
Endpoint options
Including the start date is useful when work begins that day. Excluding it is useful when counting days after a request is received.
FAQ
Are public holidays excluded?
Only the holidays you enter are excluded. Add each holiday as a YYYY-MM-DD date, separated by commas or new lines.
Are weekends counted in the business-day total?
No. Saturdays and Sundays are reported separately from the Monday through Friday business-day count.
