How U.S. Holiday Dates Are Calculated
U.S. holidays split into two types: fixed-date and floating. The difference matters because you can pencil in Christmas every December 25 without thinking twice, but Thanksgiving requires a calendar lookup every single year.
Fixed-Date Federal Holidays and Observances
Fixed-date holidays land on the same date in the Gregorian calendar every year. Christmas is always December 25. Independence Day is always July 4. Simple. But here's the wrinkle: when a fixed-date federal holiday falls on a Saturday, the official observance shifts to the Friday before. Fall on a Sunday, it moves to Monday. That's why you might get December 26 off from work in a year when Christmas lands on a Saturday; the calendar date and the federal observance date aren't always the same thing.
Floating Holidays and Day-of-Week Rules
Floating holidays are anchored to a weekday within a month, so they move around every year. Most of that traces back to the Uniform Monday Holiday Act of 1971, which shifted several federal holidays to Mondays to create more three-day weekends. Memorial Day, Presidents Day, and Labor Day all follow that pattern: last Monday in May, third Monday in February, and first Monday in September respectively. Thanksgiving is its own thing: it's the fourth Thursday in November, not a Monday, which is why it can't just be memorized. Mother's Day is the second Sunday in May; Father's Day is the third Sunday in June.
How Easter's Date Is Calculated — The Computus
Easter is genuinely the hardest one. It's a movable feast, which is a formal way of saying the date floats based on the moon rather than the calendar. The rules go back to the Council of Nicaea in A.D. 325, when church leaders established that Easter would fall on the first Sunday after the Paschal full moon. That's not the same as the actual full moon you'd see in the sky. It's an ecclesiastical approximation built on a 19-year lunar pattern called the Metonic cycle, pegged to March 21 as the church's fixed spring equinox.
The formula we use is the Anonymous Gregorian algorithm, sometimes called the Meeus/Jones/Butcher algorithm. It's the same calculation an unidentified reader sent to Nature magazine in 1876, and it's still the standard today. Because the lunar and solar calendars don't line up neatly, Easter can land anywhere from March 22 to April 25, a 35-day window. That lunar connection comes from Passover: early Christians tied the Resurrection to the Jewish Passover feast, which follows the Hebrew lunar calendar, and the date math followed from there.
U.S. Holiday Dates This Year
Floating holidays like Thanksgiving, Easter, and Labor Day shift every year. The dates below show exactly where they land this year, all computed in your browser.
Dates shown are the calendar occurrence of each holiday. Federal observance dates can differ when a holiday falls on a weekend. No manual updates needed — everything recalculates fresh each year.
