Towel Day is the creation of "a bunch of Douglas Adams loving ape descendants who thought it was a shame that [towelday.org] was parked, and bought it." Unaffiliated, they say, with the Adams estate or with any of the late Mr. Adams' publishers, the proponents of Towel Day seem to have picked May 25 for their event at random, the day being neither the date of Douglas Adams's birth or death, or in any other way (that we could discover) pertinent to the Hitchhiker's Guide to the Galaxy series.
In other words, the setting of Towel Day on May 25 seems to have been entirely random.
We believe Mr. Adams might have approved.
In any event, if you're not an Adams aficionado (or if you simply can't locate your towel), don't panic. You have other options tomorrow (although we must urge you to find your towel as soon as possible and to keep it ever handy thereafter).
Saturday, May 25 is National Tap Dance Day (and, not coincidentally, in our opinion, also the anniversary of the birth of Bill "Bojangles" Robinson -- born May 25, 1878).
And Usual Suspect Punchbowl.com is among those insisting that Saturday is also National Wine Day. We'll drink to that.
Star Wars premiered on May 25, 1977. If you're one of those people who insist on referring to this movie as "Episode IV: A New Hope," you are also probably not surprised to see that May 25 is also Geek Pride Day.
We told you that International Jazz Day was April 30. Some of the Usual Suspects tout the Saturday before Memorial Day (i.e., tomorrow) as International Jazz Day as well. We're willing to have two Jazz Days, but we have to note the seeming duplication.
On a more serious note, Saturday is also National Missing Children's Day.
