Bicycle Day commemorates the first intentional LSD trip taken by Swiss chemist Albert Hofmann on April 19, 1943. On this day, Hofmann ingested lysergic acid diethylamide and experienced its psychedelic effects while riding his bicycle home from his laboratory. This pioneering event sparked global interest in LSD’s potential for expanding consciousness. Enthusiasts celebrate with bicycle rides, art exhibitions, and discussions on the science and history of psychedelics. Festivals often feature music, workshops, and creative performances that explore the cultural impact of LSD.

Saint Ælfheah, also known as Alphege, served as Archbishop of Canterbury from 1006 until his martyrdom in 1012. Renowned for his charity and piety, he negotiated peace during turbulent times in medieval England. Captured by Viking raiders, he was killed on April 19, 1012, after refusing to allow a ransom to be paid. Canonized in 1078, Ælfheah remains a symbol of compassion and sacrifice. Devotees honor his memory through special prayers, liturgical services, and historical reflections on his life.
