Federal holidays
Every federal holiday in a year, and the day offices actually close
The eleven holidays in 5 U.S.C. § 6103, computed from the statute rather than copied from a list — so the third Monday in January is worked out for the year you ask about, and a holiday that lands on a weekend shows the day off separately from the date itself.
The federal holidays — the date in the statute, and the day offices close
| Holiday | Date | Falls on | Observed |

Computed from the statute, not stored as a list
Six of the eleven federal holidays have no fixed date. Thanksgiving is the fourth Thursday in November; Memorial Day is the last Monday in May; Labor Day the first Monday in September. Those are rules, and this page applies them to whichever year you ask about rather than looking the answer up. The five that do have fixed dates — New Year's Day, Juneteenth, Independence Day, Veterans Day and Christmas — still move in the sense that matters, because the day offices close depends on which weekday the date lands on.
The holiday and the day off are two different facts
Two different authorities are at work here, and most calculators run them together. The Saturday rule is in the statute: 5 U.S.C. § 6103(b) substitutes the preceding Friday when a holiday falls on a Saturday. The Sunday-to-Monday rule is not in the statute — it comes from Executive Order 11582 of 1971, which set the observance for employees whose basic workweek does not include Sunday. Both are real; only one is in section 6103. So in 2026 Independence Day is Saturday 4 July, and the federal holiday people actually get is Friday 3 July. Both appear in the table above, in separate columns, because collapsing them into one date is the single most common error in a holiday calculator — and it is the error that matters, since anyone counting working days needs the observed date and anyone writing about the holiday needs the statutory one. It is not a rare case either: across 2000–2029 the two dates diverge 38 times, which is closer to thirteen times a decade than to the once-in-a-while it is usually treated as.
There is a further wrinkle the business-day counter handles and this page does not need to: when the observed date is in a different year from the holiday. New Year's Day 2028 falls on a Saturday, so it is observed on Friday 31 December 2027. A working-day count for December 2027 that only looked at 2027's holidays would miss it.
The list itself changes, and the years matter
Federal holidays are created by statute, so the correct list depends on the year. Juneteenth National Independence Day was added in 2021, which means 2020 had ten and 2021 had eleven. The Birthday of Martin Luther King, Jr. was signed into law in 1983 but first observed in 1986 — a three-year gap that is easy to get wrong and produces a phantom day off in 1984 and 1985. Each holiday carries its own start year here rather than the whole table sharing one.
The other direction is a refusal. Ask for a year before 1978 and the calculator declines and explains itself, because the modern set is not what the country observed then and a table that looks right while being wrong is worse than no table.
What is not here
Easter is not a federal holiday, and neither is any of the church year that hangs off it — those live on the Easter page, where both the Western and Orthodox reckonings are computed along with Ash Wednesday, Good Friday, Ascension and Pentecost. State holidays are not here either: they vary, and several states observe days no federal office recognises. Nor are the occasional executive orders that close offices on a Christmas Eve, because a one-off order for one year is not a rule anything can compute.
