Here is a website with listings of many,many observances for the entire year.
I didn't know there was a day to celebrate chicken, cartoonists, or windmills;
and that's just a few listed for May.
If you want a reason to party or just like random info, this is the site for you :)
Have fun with it, look up what is noted on your birthday.
on mine is 'Dump your significant jerk Day' and it's national Jello-week :)
Have fun with it.
