The Origins: How and Why 420 Became a Holiday
The story of why 420 became a holiday starts in the early 1970s. A group of five teens at San Rafael High School in Marin County, California — nicknamed the “Waldos” — met at 4:20 p.m. after class to search for a rumored abandoned cannabis crop. They used “420” as their private code word.
From there, the term spread through the Grateful Dead community and later High Times magazine, which helped transform an inside joke into cultural shorthand. By the early 1990s, the first public 4/20 gatherings were already taking place in San Francisco’s Golden Gate Park, marking a shift from a secret meet-up to an open celebration.
By the late 1990s, April 20 (4/20 in U.S. format) had become an unofficial cannabis holiday recognized across North America.
