The annual observance of Veterans Day in the United States occurs on a fixed date: November 11th. This date was chosen to commemorate the armistice that ended the major hostilities of World War I, which went into effect on the 11th hour of the 11th day of the 11th month of 1918. Originally known as Armistice Day, the holiday was renamed Veterans Day in 1954 to honor American veterans of all wars, not just World War I.
Because Veterans Day is a federal holiday established on a specific date, the primary commemorations and ceremonies take place on November 11th, regardless of the day of the week on which it falls. In practice, if November 11th occurs on a Saturday or Sunday, the federal government and many other institutions may observe the public holiday on the adjacent weekday (Friday or Monday, respectively), resulting in closures and a day off from work. The official, historical commemoration, however, remains fixed to the 11th.
