CelebStoner's Ultimate 2021 4/20 Event Guide

This year is the 50th anniversary of the coining of 420.

Due to Year Two of the Covid pandemic, there will be limited 4/20 activities in 2021.

The 420 phenomenon burst onto the Grateful Dead scene in 1990 when a flyer telling the story of 420 was distributed in the Oakland Coliseum parking lot. That origin story was updated in 1996 by former San Rafael High School students who called themselves the Waldos and claimed to have coined the term in 1971.

The original flyer floated the idea of communal gatherings on 4/20: "We're talking about the day of celebration, the real time to get high, the grand master of all holidays: 4/20, or April 20th. This is when you must get the day off work or school."

With that in mind, here are 35 events scheduled on and around this year's 4/20 stoner holiday and several cancellations.
