Towel Day 2005, Innsbruck, Austria, where, by his own accounts, Adams got the inspiration to write the Guide.
|Official name||Towel Day|
|Observed by||fans of the author Douglas Adams|
|Observances||carrying a towel throughout the day|
|Related to||Douglas Adams, The Hitchhiker's Guide to the Galaxy|
Towel Day is celebrated every May 25 as a tribute by fans of the late author Douglas Adams. On this day, fans carry a towel with them to demonstrate their love for the books and the author. The commemoration was first held in 2001, two weeks after Adams' death on May 11, 2001. The towel is a reference to Adams's popular science fiction comedy series The Hitchhiker's Guide to the Galaxy.
The original article that began Towel Day was posted at "Binary Freedom", a short-lived open source forum.
Towel Day: A Tribute to Douglas Adams
Monday May 14, 2001 06:00am PDT
Douglas Adams will be missed by his fans worldwide. So that all his fans everywhere can pay tribute to this genius, I propose that two weeks after his passing (May 25, 2001) be marked as "Towel Day". All Douglas Adams fans are encouraged to carry a towel with them for the day.
So long Douglas, and thanks for all the fish!

Chris Campbell and his friends registered the website towelday.org to spread the word, reminding people not to forget to bring their towels. Towel Day was an immediate success among the fans and many people sent in pictures to show off themselves with their towels. 
|“||A towel, it says, is about the most massively useful thing an interstellar hitchhiker can have. Partly it has great practical value. You can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapors; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a miniraft down the slow heavy River Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or avoid the gaze of the Ravenous Bugblatter Beast of Traal (such a mind-boggingly stupid animal, it assumes that if you can't see it, it can't see you); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.||”|

Towel Day was also recognized by several smaller members of the media, especially Swedish newspapers and news sites on the web. Its web presence has grown significantly in recent years, expanding to include posts on self-proclaimed "nerd news" site Slashdot , a special hashtag on popular blogsite Twitter (#towelday), and sites dedicated specifically to this event, such as IsItTowelDay.com  and TowelDay.org .
