In church reckoning the evening of December 24 is already Christmas, not its run-up. In law it is a rest day in Czechia, absent from the nine holidays Germany protects nationwide, and a yearly presidential decision in the US.
Christmas Eve has no founder and no establishing act; it is the vigil of the Nativity. The Universal Norms on the Liturgical Year run the liturgical day from midnight to midnight, then begin the celebration of a Solemnity on the evening of the previous day, and they rank the Nativity among the two greatest Solemnities.
Christmas Eve is not one of the legal public holidays of the United States, and the federal government keeps closing for it anyway. December 24 appears nowhere in 5 U.S.C. section 6103, which lists eleven of them and ends at Christmas Day.
The closures came anyway, 28 of them between 1937 and 2025. Each was a separate executive order excusing federal employees for all or part of December 24, and each covered a single year. Across those decades the day off arrived in fewer than half the years it could have.
The improvisation is not confined to the United States. Four national legal systems answer the question four different ways, and only one gives December 24 the plain status of a holiday; the others reach it sideways or not at all.
DEALS & OFFERS
Christmas Eve ran on December 24 without a tracked deal. Browse past offers from previous years.
On the evening of 24 December 1818, a new song was heard for the first time at the Christmette in the church of St. Nikola in Oberndorf. Joseph Mohr had written the words at Mariapfarr two years earlier, and Franz Xaver Gruber set them to music. Gruber played the organ at Oberndorf from 1816 to 1829.
That night was already Christmas by the Church's own reckoning, which counts the evening of the 24th as part of the Nativity rather than the approach to it. A service held then falls inside Christmas instead of before it.
Civil law reckons the other way, and in the United States the gap gets closed by hand. Franklin D. Roosevelt signed Executive Order 7763 on 6 December 1937, titled "Excusing Federal Employees from Duty on December 24, 1937".
Seventeen years and three presidents on, Executive Order 10580 gave federal employees the whole of December 24, Eisenhower's second in two years. The series splits evenly on that question, 14 orders granting a full day and 14 a half.
The statute that leaves December 24 out also supplies the way around it. Subsection (b) extends holiday pay and leave rules to "any other day declared to be a holiday by Federal statute or Executive order".
Executive Order 14129 uses it in the open. Its first section closed every executive department and agency on "Tuesday, December 24, 2024, the day before Christmas Day", and its third section places the date within the scope of section 6103(b) for pay and leave.
The most recent is Executive Order 14371, signed on 18 December 2025. It closed federal offices on December 24 and again on December 26, with Christmas Day falling on the Thursday between them.
So the law and the liturgy disagree about when Christmas starts, and the liturgy got there first. Oberndorf was singing on the evening of the 24th more than a century before the earliest of these orders was signed.
BY THE NUMBERS
TIMELINE
GOOD TO KNOW
Štědrý den is a day of work rest under section 3 of Act No. 245/2000 Sb., alongside 25 and 26 December
julaften is not one of the helligdager, yet the 1995 holy-days act requires holy-day peace after 16:00 that no one may disturb with undue noise
Heiligabend is not among the nine holidays the federal interior ministry lists as protected in every Land, a list that ends at the first and second Christmas days
December 24 appears nowhere in the federal holiday statute, 5 U.S.C. section 6103, so federal offices close only when the president signs an executive order covering that year
GOOD TO KNOW
Across 4,834 executive-order entries parsed from the National Archives disposition tables for 1937 to 2005, not one title contains the word. The orders write the calendar date instead.
Lyndon B. Johnson and Gerald Ford issued no December 24 closure order. Ford's December order, Executive Order 11891 of 1975, covered December 26 instead.
Executive Order 12619 was signed on 22 December 1987 for 24 December 1987, the tightest notice in the series, and it granted a half day.
December 24 fell on a Thursday twelve times, and nine of those years got an order. Mondays ran eight of twelve. Wednesdays managed two of thirteen. A closure that bridged to a weekend was roughly three times likelier than one stranded mid-week.
Frank Borman recalled the briefing in 2008: "We were told that on Christmas Eve we would have the largest audience that had ever listened to a human voice. And the only instructions that we got from NASA was to do something appropriate." The NASA history of the flight carries the broadcast and the Earthrise photograph.
WHY THIS DAY MATTERS
Even the 2024 closure order let agency heads keep the doors open.
In 2024, Executive Order 14129 closed federal offices and then let agency heads keep them open anyway, requiring staff to report "for reasons of national security, defense, or other public need."
Silent Night sits on Austria's national inventory of intangible cultural heritage, inscribed in 2011 as a focal point of the country's Christmas Eve celebration. The commission records the carol as translated into some 300 languages.
The Universal Norms on the Liturgical Year extend the celebration of the Nativity over eight days, as they do for Easter, the two the Norms call the greatest Solemnities. So Christmas is under way before the 25th arrives.

It depends on the country. Czech law makes 24 December a day of work rest, while in the United States it is not a legal public holiday and December 24 appears nowhere in 5 U.S.C. section 6103.
