us-federal-holidays.com is a reference site for the dates of the 11 US federal holidays and for what is open or closed on each. It is maintained by the editorial team and is independent: it is not a government website and is not affiliated with OPM, USPS, the Federal Reserve or any exchange.
How dates are verified
- Computed from the rule. Every holiday date is generated by code from the definition in the statute (for example, “last Monday in May”), using the open-source python-holidays library.
- Compared with the official schedule. The output is matched against the federal holiday tables published by the US Office of Personnel Management. A page is not published if the two disagree.
- Weekday checked separately. Each written date, such as “Monday, May 31, 2027”, is re-tested by a script to confirm that the weekday matches the date.
- Dated. The foot of every page shows when it was last checked.

What we do not claim
State holiday information is compiled from state holiday rules and can change by proclamation; it is labeled as such, and the state’s own calendar prevails. Dates beyond the years OPM has published are calculated and marked. Nothing here is legal, payroll or financial advice.
