Veterans Day is observed annually in the month of November, specifically on the 11th day. The keyword term "month" is a noun. In this context, it functions as the central point of the query, specifying the temporal scope of the question and serving as the primary categorical identifier for the holiday's date.
The selection of November 11th is historically significant, originating from the commemoration of Armistice Day. This date marks the anniversary of the armistice signed between the Allied nations and Germany, which ended the major hostilities of World War I at the 11th hour of the 11th day of the 11th month in 1918. In the United States, legislation was passed in 1954 to officially change the name from Armistice Day to Veterans Day, expanding its purpose to honor American veterans of all wars.
Unlike holidays that are designated to occur on a specific day of the week, such as Memorial Day, Veterans Day is a fixed-date federal holiday. The observance is consistently held on November 11th regardless of the day on which it falls. If the date occurs on a weekend, the federal public holiday and associated closures are typically observed on the adjacent weekday (Friday if the 11th is a Saturday, or Monday if it is a Sunday), but the historical and ceremonial focus remains on November 11th.
