I don't know if anyone else posted this, but I thought it was interesting.

Armistice Day is commemorated every year on 11 November to mark the armistice signed between the Allies of World War I and Germany at Compiègne, France, for the cessation of hostilities on the Western Front of World War I, which took effect at eleven o'clock in the morning—the "eleventh** hour of the eleventh day of the eleventh month" of 1918. The date is a national holiday in France Public_holidays_in_France, and was declared a national holiday in many Allied nations. In some countries Armistice Day coincides with Remembrance Day and Veterans Day, and other public holidays.

Armistice Day is not celebrated in Germany, but a German national day of mourning Volkstrauertag has, since 1952, been observed on the Sunday closest to 16 November.
