Business Day Calculator

Count working days between two dates, or add business days to a date to find a deadline. Weekends and US federal holidays are skipped.

Which days are excluded

Saturdays, Sundays and the 11 federal holidays are excluded, using the observed date when a holiday falls on a weekend. State holidays (such as Patriots' Day or Cesar Chavez Day) and company-specific days off are not included; subtract them manually if they apply to you.

Business days per year

There are 260 to 262 weekdays in a year; after removing federal holidays, about 250 business days remain. Set the range from January 1 to December 31 to get the exact figure for any year.

Frequently Asked Questions

What counts as a business day?
In the US a business day is Monday through Friday, excluding federal holidays. Tick "Saturday is a working day" if your workplace runs six days a week.

How do I add 10 business days to a date?
Open "Add business days", pick the start date and enter 10. The start date is not counted; weekends and federal holidays are skipped until the 10th working day.

Are federal holidays business days?
No. Federal offices, the Federal Reserve and most banks are closed. When a holiday falls on a weekend the observed weekday is treated as the holiday.

How many business days are in a year?
A year has 260 or 261 weekdays (262 in some leap years). Removing the 11 federal holidays that fall on weekdays leaves about 250 business days.
