Where Did 420 Day Get Its Name?
The origin of “420” is deeply rooted in American cannabis folklore. The story begins in San Rafael, California, in 1971, when a group of high school students made a pact to search for an abandoned cannabis crop using a map left behind by the grower. They agreed to meet after school at 4:20 PM, using “420” as their secret code.
Although they never located the mysterious crop, the term stuck — becoming a private shorthand within their circle before spreading through California’s counterculture. The phrase gained national attention in 1991 when High Times wrote about “420,” mistakenly connecting it to a police code.
By the mid-1990s, 420 had become a nationwide cultural symbol, representing cannabis, community, and celebration. And of course, the date 4/20 (April 20th) became the official day America honors the plant.
