The Origins of 420 Day

Legend has it that the term "420 day" can be traced back to 1971 when a group of high school students embarked on a quest to find a hidden cannabis plantation, guided only by a map from the original cultivator. Their rendezvous point was outside the San Rafael High School at 4:20pm, marking the start of their adventure. Although the mythical plantation remained elusive, "420" evolved into their secret code for cannabis use. This term went mainstream in the 90s, where it eventually become emblematic among cannabis aficionados, designating April 20th as a day dedicated to celebrating their beloved herb. The date 4/20 was chosen for its backward reading of '420', ingeniously linking it to the culture.
