How to Calculate Business Days Excluding Weekends and Holidays

Updated October 20, 20262 min read

"Delivered within 10 business days", "payment due in 30 working days", "respond within 5 business days" — deadlines like these skip weekends and public holidays, which makes them annoying to count on a calendar.

Counting business days between two dates

  1. Open the business days calculator.
  2. Pick the country whose public holidays apply.
  3. Enter the start and end dates.

The result shows business days, weekend days and the holidays that fell on weekdays, with the list of those holidays. In this count both the start and end dates are included if they're working days.

Adding business days to a date

To find a deadline, use the second part: enter a start date and the number of business days. Counting starts on the next working day, which matches how most contracts and carriers read "within N business days".

Which holidays are included

The tool covers national holidays for the US, Canada, UK (England & Wales), Australia, Germany, France, Italy, Spain, Portugal, Mexico, Colombia, Brazil, Japan, South Korea and Taiwan, including observed or substitute days. Regional holidays (US states, Canadian provinces, German states, Australian states) aren't included — subtract them yourself if they apply to you.

Watch out for

  • Company closures such as the week between Christmas and New Year aren't public holidays.
  • Saturdays: some businesses and countries treat them as working days — there's an option for that.
  • Cut-off times: an order placed after 5 pm often counts from the next business day.

If weekends should count, use Days Between Dates instead.
