Counting rules

What counts as a business day?

Weekdays

Monday through Friday count unless the selected holiday calendar marks the date as a national holiday.

Observed holidays

When a fixed holiday falls on a weekend, its cataloged weekday observance is excluded. The weekend date remains classified as a weekend.

Endpoints

Between-date mode lets you include or exclude each endpoint. Add/subtract mode excludes the starting date unless you choose to count it.
