What is 420?

420 is a slang term (or a kind of code word) referring to marijuana or marijuana use.

Due to this association, 420 is also used as the name of an unofficial holiday that marijuana enthusiasts celebrate by using marijuana. It is sometimes called Weed Day (weed is a slang term for marijuana).

When is 420?

420 is April 20—aka 4/20.

More information and context on 420

The first records of the term 420 in the context of marijuana come from the early 1970s. It most likely began as a code word among a small group of California highschoolers whose regular meeting time to smoke weed was at 4:20 p.m. (There does not seem to be any evidence for theories involving 420 being a criminal code violation number or a police radio code.) It was later popularized in part by fans of the band the Grateful Dead.

As the term became more well-known, the date of April 20 (written in the month/day date format as 4/20) became recognized among marijuana users as a day to indulge in its use. The time 4:20 is sometimes used in the same way (with 4:20 on 4/20 being especially popular among some celebrants).

While 420 has traditionally been an excuse for people to get together and smoke weed, it is sometimes used a day to hold organized events, such as rallies to support the legalization of marijuana. It has become even more well-known as marijuana becomes legal in many locations.

420 is not the only unofficial holiday based on a particular date representing something in pop culture. March 14 has become known as Pi Day due to its date (written in the month/day format as 3/14) resembling an approximation of pi (3.14). May 4 is sometimes called Star Wars Day because May the Fourth sounds like the beginning of the well-known Star Wars greeting May the force be with you.
