Add Business Days to a Date

A business day (or working day) is any weekday — Monday through Friday — that isn't a public holiday. Saturdays, Sundays, and federal holidays are not business days. This calculator counts Monday–Friday by default and can also skip the 11 US federal holidays.

Count every weekday from the day after the start date through the end date, skipping Saturdays, Sundays, and any holidays. For example, Monday to the following Friday is 4 business days. Rather than counting by hand, enter both dates above and the calculator does it instantly — with an option to include holidays or not.

By default it counts the business days after the start date through the end date (so a Monday-to-Friday span is 4). Turn on 'include start date' to count the start day too, which makes the same span 5. The end date is always included when it's a business day.

The 11 US federal holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas. When a fixed-date holiday lands on a weekend, the observed date shifts to the nearest weekday, and the calculator uses the observed date. Turn holidays off to count weekdays only.

Use the 'add business days' mode: enter a start date and a number of business days, and the tool lands on the resulting weekday, skipping weekends and holidays. Enter a negative number to go backward. This is how shipping and lead-time estimates like 'ships in 3 business days' are calculated.

Banks, courts, government offices, and shipping carriers operate on business days, so deadlines and delivery estimates are usually quoted in them — 'funds available in 2 business days,' 'respond within 10 business days.' Counting them correctly (and accounting for holidays) is the difference between hitting and missing a deadline.
