Bicycle Day (Psychedelic Holiday)


global holiday on April 19th celebrating the psychedelic revolution[1] and commemorating the first psychedelic trip on LSD by Dr. Albert Hofmann in 1943, in tandem with his famous bicycle ride home from Sandoz Labs.[2][3] It is commonly celebrated by ingesting psychedelics and riding a bike, sometimes in a parade,[4] and often with psychedelic-themed festivities.[5] The holiday was first named and declared in 1985 by Thomas Roberts, a psychology professor at Northern Illinois University,[6][7] but has likely been celebrated by psychedelic enthusiasts since the begining of the psychedelic era, and celebrated in popular culture since at least 2004.[8] History[edit] On April 19, 1943, Albert Hofmann ingested 0.25 milligrams (250 micrograms) of LSD.
