All U.S. holidays & observances

How to use this index

Every entry links to a full page: the rule that sets the date, dates for 2026 through 2027, the history, quick facts and a set of questions people actualy ask about it. American holiday pages add a service-by-service closure table — post office, banks, stock market, federal and state offices, schools, stores — and, where the answer varies by state, a table showing which states treat the day as a paid holiday, which treat it as an observance, and which ignore it entirely.

The list is grouped by legal status rather than by season, because that distinction decides almost everything practical. Federal holidays close offices across the United States. State holidays close them only where they apply, which is why the state pages exist. Observances are widely marked but close nothing at all. If you know the date rather than the name, the countdown pages cover every day of the year, and the search box at the top of the page matches alternative names too — searching "Washington's Birthday" finds Presidents' Day, and "Decoration Day" finds Memorial Day.
