Weekends are Saturday and Sunday. Add the holidays that apply to your employer, market, school or jurisdiction.
How this tool works
The calculator walks each calendar date in the interval, excludes Saturdays and Sundays, then excludes any valid holiday dates entered by the user.
Example
Count the business days in September and add Labor Day to the holiday list so it is not treated as a workday.
Common questions
Are federal holidays automatic?
No. Holiday calendars vary by country, market and employer, so you explicitly enter the dates to exclude.
Can I include the starting day?
Yes. A checkbox controls whether the first date is counted when it is an eligible business day.
