Observed days matter
If a fixed federal holiday lands on a weekend, the nearby observed weekday is skipped too.

Business-day questions.
What counts as a business day?
This calculator treats Monday through Friday as business days, then optionally excludes observed U.S. federal holidays. Your employer or organization may follow a different schedule.
Does the calculator include the starting date?
Counting between dates always begins with the start date and lets you decide whether to include the end date. When adding workdays, the start is excluded unless you turn on “Count the starting date.”
Which holidays are excluded?
The calculator uses the 11 annual nationwide federal holidays and their usual observed weekdays. Inauguration Day is not included because it applies only to certain federal employees in the Washington, D.C. area.
Can I use this for a legal deadline?
Use it as a planning aid, not as legal advice. Courts, contracts, agencies, delivery services, and state rules can define “business day” differently.
