During World War I, on November 11, 1918, at 5:00am, the Allied and German delegates signed an armistice; at 11:00 the same morning, hostilities along the Western Front officially came to an end. The end of the war on the "11th hour of the
11th day of the 11th month of 1918" was selected so every person would remember the exact moment when the last war was ever fought. (Obviously, this was not the case.) Still, the next year, President Woodrow Wilson proclaimed November 11th as "Armistice Day". A Congressional Act in 1938 made the 11th of November of every year "Armistice Day". Congress amended its own act in 1954 and renamed the holiday "Veterans Day", which is observed every year. [Click the picture to read more about World War I.]
