The central component of the keyword subject is "Veterans Day," which functions as a proper noun. As the subject of the inquiry, this noun identifies a specific federal holiday in the United States. The phrase "November 11" acts as a noun phrase in apposition, specifying the exact date on which this holiday is observed. Grammatically, the core of the topic is this proper noun, representing the event itself.
The selection of November 11 is historically significant. The date marks the anniversary of the armistice that ended major hostilities of World War I, which formally went into effect on the eleventh hour of the eleventh day of the eleventh month in 1918. Initially commemorated as Armistice Day to honor the veterans of World War I, the day was recognized for its connection to world peace and the conclusion of the "war to end all wars."
In 1954, following World War II and the Korean War, the U.S. Congress amended the act to change the name from "Armistice Day" to "Veterans Day." This legislative change broadened the holiday's purpose. It was transformed from a day honoring the veterans of a single conflict into a day dedicated to honoring all American veterans, living or dead, who have served in the United States Armed Forces during both wartime and peacetime.
