More about Veteran's Day - On November 11 at 11:11, 1921 the U.S. France and England each buried an unknown soldier in honor of those who died in World War I. This began the annual Armistice Day holiday. The time and day was picked because fighting ceased in WWI in 1918 on November 11 at 11:11. In keeping with this tradition, work stops on this day and time each year for a moment of silence.
