Every year on April 20, marijuana enthusiasts collectively blaze it up in celebration of Weed Day. The cannabis-centric holiday falls on April 20 because when the date is written out numerically (at least in the United States), you get 4/20 — the number "420" has become synonymous with marijuana. In honor of the day, let's expand your mind and knowledge with these seven things you might not have known about the term "420."
1. The origin of the term involved five high school students in 1971.
"The Waldos" (because the five teenagers always hung out near a wall) would meet by a statue of Louis Pasteur near San Rafael High School at 4:20 p.m., before they'd go looking for an alleged marijuana crop in Point Reyes, California.
The term, not the use of marijuana (although they're fans of that too).
3. 420 isn't a penal or police dispatch code for illegal marijuana use.
4. Technically speaking, "4/20" doesn't exist in Europe.
Because Europeans write their dates as day, month and year, so April 20 is written out as "20/4."
5. Fittingly, California's senate bill number for the state's "Medical Marijuana Program Act" is called "SB 420."
6. 420 doesn't refer to the number chemicals in cannabis.
But it's not too far off; marijuana contains approximately 500 different chemical constituents.
7. The bible verse Daniel 4:20 is about a "tree."
The tree you saw, which grew large and strong, with its top touching the sky, visible to the whole earth, with beautiful leaves and abundant fruit, providing food for all, giving shelter to the wild animals, and having nesting places in its branches for the birds— Your Majesty, you are that tree! You have become great and strong; your greatness has grown until it reaches the sky, and your dominion extends to distant parts of the earth.
