Worked example: Monday, October 26, 2026 to Friday, December 25, 2026

Calendar days: 60 (or 61 if you count both the first and the last day).
That is 8 weeks and 4 days.
Business days: 41. Weekends are left out, and so are the federal holidays in that period (Veterans Day, Thanksgiving and Christmas Day).

How this is worked out

Exclusive count (the default): the difference between the dates, so Monday to Tuesday is 1 day.
Inclusive count: both the first and last day are counted, so Monday to Tuesday is 2 days.
Business days are Monday to Friday, excluding observed US federal holidays. In an exclusive count the first date is not counted; in an inclusive count it is, when it is a business day.
Holidays follow today's federal rules for every year, except Juneteenth, which counts only from 2021, when it became a federal holiday.
The dates can be entered in either order. Leap days are counted automatically.

Frequently asked questions

What is the difference between an inclusive and an exclusive count?: An exclusive count gives the difference between the dates, so Monday to Tuesday is 1 day. An inclusive count includes both the first and last day, so Monday to Tuesday is 2 days.
Are leap years counted?: Yes. February 28 to March 1 is 2 days in a leap year such as 2028 and 1 day in a common year such as 2027.
How are business days counted?: Business days are Monday to Friday, excluding observed US federal holidays. State, local and company holidays are not excluded.
Does the order of the dates matter?: No. The count is the same whichever date you enter first.
