      Examples

      Working days in January 2027 (U.S.)

      January 2027 starts on a Friday, so its 31 days include 10 weekend days, leaving 21 weekdays. New Year’s Day (Friday, January 1) and Martin Luther King Jr. Day (Monday, January 18) both fall on weekdays, so the month has 19 business days.

      A 10-business-day deadline

      An invoice dated Wednesday, November 18, 2026 is due in 10 business days. Counting from the next day and skipping the weekends and Thanksgiving (November 26), the deadline is Thursday, December 3, 2026.

      Which holidays are skipped

      United States: the 11 federal holidays, worked out for any year. When one falls on a Saturday it’s observed on the Friday before; on a Sunday, the Monday after. State and local holidays aren’t included; add them under Custom days off if they matter to you.

      Private employers don’t have to give any of these days off, and most give about six. Open Which holidays to untick the ones you work, or tap Typical private employer.

      United Kingdom: bank holidays for England & Wales, Scotland or Northern Ireland, including the holidays whose dates move each spring. A bank holiday that falls at a weekend moves to the next weekday. One-off holidays, such as a coronation, need adding as custom days off.

      Your weekend can be Saturday–Sunday, Friday–Saturday or Sunday only.

      Business days per month

      Monday-to-Friday working days in each month, minus public holidays that fall on weekdays.

      Frequently asked questions

      What counts as a business day?
      Monday to Friday, excluding public holidays. That’s the definition banks, courts and government offices use.
      Should I include the start date?
      For “how many working days are in this period?”, count both dates. For deadlines such as “within 5 business days of the 3rd”, the start day usually isn’t counted, which is how the Add days tab works.
      How long is 3 to 7 business days?
      About one to one and a half weeks. An order placed on a Monday would arrive between Thursday that week and Wednesday the next, if there are no holidays.
      How do I count business days in Excel?
      =NETWORKDAYS(A1,B1,holidays) counts weekdays between two dates, including both ends, minus any dates in the holidays range. =NETWORKDAYS.INTL lets you choose a different weekend, and =WORKDAY(A1,10,holidays) finds the date 10 business days later.
      How many business days are in a year?
      About 250 in the U.S.: 260 or 261 weekdays minus 11 federal holidays. Count January 1 to December 31 above for the exact number in any year.
