*Armistice Day (also known as Remembrance Day) is on November 11 and commemorates the armistice signed between the Allies of World War I and Germany at Compiègne, France, for the cessation of hostilities on the Western Front, which took effect at eleven o'clock in the morning of the "eleventh hour of the eleventh day of the eleventh month" of 1918. The date was declared a national holiday in many allied nations to commemorate those members of the armed forces who were killed during war. In many parts of the world people take a two-minute moment of silence at 11:00 a.m. as a sign of respect for the roughly 20 million people who died in the war . . . In the United States, November 11 is celebrated as Veteran’s Day, honoring all military veterans (Memorial Day, May 30, honors and remembers those who have died in service to their country).
