I just found out about this around 10 minutes ago. I've been playing Zelda since I was a kid - must've been around 4 or 5 when I played A Link to the Past (which is still my favorite). The only games I haven't played are the GBA editions and Skyward Sword, but that will probably change in the future.
The basic gist of everything is to just celebrate your time as a Zelda series player. I know I will.

Ha! What a cool holiday!
There is no one such day. As Zelda pride day to me is basically everyday. And I do randomly draw a triforce on my hand. Actually dressed as a would be thug one year for halloween to have a case of Deja Vu upon seeing the Twilight Princess version of yonder ganondorf. lol. Seriously though. They have an actually day picked for that? Epic. All i'll say. Epic.
