420
Monday, April 20, 2026
April 20 (4/20) is an informal global counterculture holiday celebrating cannabis, its culture, and advocacy for legalization and reform. It is marked by gatherings, education, and consumption in places where it is legal
History
The term '420' originated in the early 1970s among a group of high school students in San Rafael, California, who used '420' as a code for meeting after school to smoke cannabis. It spread through Grateful Dead fans and High Times magazine, eventually becoming a worldwide symbol for cannabis culture and the movement to end prohibition
How It's Celebrated
In jurisdictions where legal, people gather for educational events, festivals, and peaceful celebrations. Many use the day to advocate for sensible drug policy reform, support cannabis businesses, learn about medical uses, or simply enjoy the plant responsibly. Always follow local laws.
