Armistice Day commemorates the end of World War I, which officially concluded on November 11, 1918, at the 11th hour. Originally established to honor the armistice agreement between the Allied Powers and Germany, this day is a reminder of the sacrifices made during the war and serves as a time for reflection on the cost of conflict. Over the years, Armistice Day has evolved into Veterans Day in the United States, recognizing all military veterans. It emphasizes the importance of peace and the need to remember the lessons of history to prevent future conflicts.
