11 November (Veterans Day) will be the 100th Anniversary of the end of WWI.
The Armistice was signed at 11:11 on 11/11, 1918.
I will be making a special trip to the Lt. Col. John McCrae birthplace museum for the 100th Anniversary of the armistice. It seems appropriate.

That is when it took effect, not signed.
