Between counts the start and the end. The default weekend is Saturday and Sunday. Friday and Saturday can be the days off. A holiday name is unknown here. Closed weekdays are subtracted only between two dates. Add does not count the start day and does not use that closed count.
Why this exists
A contract and a delivery count the days an office was open, not every square on a calendar. From 2026-01-05 through 2026-01-16 that is 10 business days.
The date-gap page does not drop weekends. This page does, and a holiday is only the number the visitor types.

01How to use it
Choose between or add, and whether the weekend is Saturday–Sunday or Friday–Saturday.
Type the dates. The large number is the business-day count. In add mode it is the landing date.
-
02What you get
The tiles show the count after weekends, the closed weekdays, and the weekday of each end.
Add shows only the landing weekday. The link keeps the dates and the weekend choice.

03Worth knowing
Add does not count the start. If Monday is the start, one business day is the next open weekday.
The result stays in this browser. It does not pretend to know a country’s holidays.

How this page works it out
A business day is a day the office was open, not every square on a calendar. From Monday 2026-01-05 through Friday 2026-01-16, both ends count and Saturday and Sunday drop out, which leaves 10 days. Two full weeks sit inside that span, and four of those days are the weekend.
Add does not count the start day. Adding 10 business days to 2026-01-05 lands on Monday 2026-01-19. The closed-weekday field is not used in add mode.
A holiday has no name on this page. One closed weekday turns 10 into 9. Switching the weekend to Friday and Saturday makes the same span 9, because Friday is off as well. The page does not fill in a country’s holiday list.
