The core subject within the query "when is veterans day this" is the phrase "Veterans Day," which functions as a proper noun. As a federal holiday in the United States, Veterans Day is observed annually on a fixed date: November 11. This date commemorates the armistice that ended World War I.
The selection of November 11 is historically significant, marking the formal agreement that ceased hostilities on the Western Front at the 11th hour of the 11th day of the 11th month in 1918. Unlike holidays that are observed on a specific Monday of a month (such as Memorial Day or Labor Day), Veterans Day maintains its connection to this specific historical date. However, there is a procedural rule for its observance: if November 11 falls on a Saturday, the federal holiday is typically observed on the preceding Friday. If it falls on a Sunday, it is observed on the following Monday.
Therefore, the date of Veterans Day is consistently November 11, chosen to honor the historical moment of the World War I armistice. The purpose of the day is to serve as a tribute to all military veterans, living or deceased, who have served honorably in the U.S. Armed Forces during wartime or peacetime. The specific day of the week on which it is observed for federal and business purposes may shift to the adjacent weekday if the 11th falls on a weekend.
