The central subject of the query is "Veterans Day," which functions as a proper noun. This U.S. federal holiday is observed on a fixed date, November 11, each year. Consequently, it occurs within a given month only if that month is November.
The date of November 11 holds historical significance, as it marks the anniversary of the armistice that ended World War I in 1918. Originally established as Armistice Day, the holiday was renamed in 1954 to honor veterans of all U.S. wars. Unlike many federal holidays that were moved to a specific Monday by the Uniform Monday Holiday Act, Veterans Day was returned to its traditional November 11 date in 1978 to preserve its historical importance.
Because the holiday is fixed on this specific date, its day of observance can vary. If November 11 falls on a Saturday, the official holiday for federal purposes is typically observed on the preceding Friday. If it falls on a Sunday, it is generally observed on the following Monday. This practice ensures that the day of remembrance is consistently recognized with a designated day off.
