The keyword phrase "when is veterans day date" functions as an interrogative clause seeking to identify a specific noun: the calendar date for the holiday. Veterans Day is observed annually in the United States on November 11. This date is fixed by law and does not change from year to year, regardless of the day of the week on which it falls.
The significance of November 11 is directly linked to the conclusion of World War I. An armistice between the Allied nations and Germany went into effect at the eleventh hour of the eleventh day of the eleventh month in 1918. This date was first commemorated as Armistice Day in 1919. In 1938, a Congressional Act made it a legal holiday. Following World War II and the Korean War, legislation was passed in 1954 to change the name to Veterans Day in order to honor American veterans of all wars. While the Uniform Monday Holiday Act briefly moved its observance to a Monday in October, strong historical sentiment led to its official return to the fixed November 11 date in 1978.
The practical application of this fixed date differs from that of "floating" Monday holidays. When November 11 falls on a Saturday, the federal holiday is generally observed on the preceding Friday. If it falls on a Sunday, the holiday is typically observed on the following Monday. This ensures that federal employees receive the designated holiday while maintaining the historical and symbolic integrity of the November 11 date itself as the primary day of commemoration for all U.S. military veterans.
