Armistice Day is observed on November 11 each year to commemorate the armistice that ended the fighting in World War I, specifically at the 11th hour of the 11th day of the 11th month in 1918. This day marks not just the cessation of hostilities on the Western Front but also represents a significant turning point in world history as it led to the eventual peace negotiations and treaties that reshaped nations and borders after the war.
