McFloozy mentioned Quack Day in February and I had a message from Valentine Mark Hermann telling me of an anniversary in February. I figured that it would be best to put all the dates in one discussion, so anyone could contribute and we could all dare each other to make stuff.
I figured it would be best to start a sub-thread for every month, with replies for the events perhaps? Let's see how it goes...
late November - PostMuse's birthday
Canada Day July 1 (my b-day!) also U.S Postage Stamp Day
Global Forgiveness Day July 7
Don't Step on a Bee Day July 10
World Population Day July 11
Embrace Your Greekness Day July 13
National Lollipop Day July 20
Korean Armistice Day July 27
