Towel Day is celebrated every year on 25 May as a tribute to the author Douglas Adams by his fans. On this day, fans openly carry a towel with them, as described in Adams' The Hitchhiker's Guide to the Galaxy, to demonstrate their appreciation for the books and the author. The commemoration was first held 25 May 2001, two weeks after Adams' death on 11 May.
Origin
The importance of the towel was introduced in The Hitchhiker's Guide to the Galaxy original radio series in 1978. The follow-up book explained the importance of towels in The Hitchhiker's Guide to the Galaxy universe in Chapter 3, using much of the same wording as the original radio series: The original article that began Towel Day was posted by a user "Clyde" at "System Toolbox", a short-lived open source forum. Chris Campbell and his friends registered the domain name towelday.org to promote the day, reminding people to bring their towels. Towel Day was an immediate success among fans and many people sent in pictures of themselves with their towels.
In Canada, Volt, a French/English television show, created a skit in which Towel Day was explained and featured. In Ecuador, Radio City, a BBC affiliated radio station, interviewed one of the organizers of Towel Day in Toronto to introduce their listeners to Towel Day. The interview was in Spanish and English.
