No Pants Day
the first Friday in May (since 1986)
No Pants Day gives everyone the perfect excuse to not wear pants. Participants go about their normal routine on the day, just without wearing pants. They act as normal as possible, as if nothing is odd about not wearing pants. By some accounts, the day started in the mid-1980s. Other accounts say it started informally in the late 1990s. This version of its provenance says that the day began being promoted in 2000, by the Knighthood of BUH student group at the University of Texas at Austin. It is unlikely that they started the day, but they were responsible for spreading its popularity. The day shouldn't be confused with No Pants Subway Ride Day, which is held in January and is organized by Improv Everywhere.
How to Observe
Celebrate the day by not wearing any pants and acting like it is completely normal. Go to your job or the grocery store without wearing pants. Of course, you still need to wear underwear. If you are still worried about being a little too risqué, put on a kilt or skirt. You still won't be wearing any pants!
