I've done a little research on strange holidays because that was going to be the focus of my website Philstivus - like that episode of Seinfeld where they come up with the holiday of Festivus, Philstivus was going to be MY personal holiday.
This in turn came about because for many, many years now I have not celebrated the normally-celebrated holidays. Christmas and Thanksgiving became non-affairs after my divorce; my birthday ceased to be anticipated somewhere around 1984. The rest, well, religious holidays are right out, non-events like President's Day and Groundhog Day were never observed to begin with, and the Hallmark Holidaze of St. Valentine's Day, Secretary's Day, Second-Cousin-Twice-Removed Day ... they deserve as much scorn as I can heap upon them.
I'm sorry if it offends anyone, but IWD is just another one of those non-events for me.
... besides, March 8th is National Thank Your Stripper Day in Philstivus.
