About Weed Day
This day is often called simply '420' - April 20th. The term 420 originated at San Rafael High School, in 1971, among a group who called themselves the Waldos. The term was a shorthand code for the time of day the group would meet to smoke pot.
In recent years, it has also gained the nickname, the 'High Holiday'.
