The Psychedelic High Holidays: Bicycle Day, 4/20, and 9/20
Psychedelic High Holidays connect three annual dates to key moments in psychedelic culture: Bicycle Day on April 19, 4/20 on April 20, and Mushroom Day on September 20. Bicycle Day centers on LSD history, tracing to Albert Hofmann and the first intentional LSD experience in 1943, including the bike ride home and the idea of peer support. 4/20 is explained as an origin rooted in a 1971 student meetup called the Waldos at 4:20 p.m. to search for an abandoned cannabis crop, not urban legends like police codes or pop culture numerology. The guide adds practical context for modern use: cannabis has the highest caller-reported distress rate on the Fireside Project psychedelic peer support line, with questions often focused on duration and overdose risk. Mushroom Day is framed as a newer, still emerging psilocybin-focused holiday coined in 2015 by Nicholas Reville, meant as an educational day of action. Fireside also highlights support options like trip sitting and scheduled TripCheck calls.
