Towel Day is celebrated every May 25 as a tribute by fans of the late author Douglas Adams. The commemoration was first held in 2001, two weeks after his death on May 11, and since then has been extended to an annual event. On this day, fans carry a towel with them throughout the day. The towel is a reference to Adams’s popular science fiction comedy series The Hitchhiker’s Guide to the Galaxy.”
