So far the majority of you are incorrect.
420's origin IS known.
the term 420 originated at San Rafael High School, in 1971, among a group of about a dozen pot-smoking wiseacres who called themselves the Waldos, who are now pushing 50. The term was shorthand for the time of day the group would meet, at the campus statue of Louis Pasteur, to smoke pot. Intent on developing their own discreet language, they made 420 code for a time to get high, and its use spread among members of an entire generation.
So there ya go, someone's parents out there invented the term 4/20.

420 has 3 meanings to fringe elements within the mob or populace. April 20 or 4/20 is Hitler's birthday to the right wing White Power movement-the date on which the Columbine school massacre occurred in Littleton Colorado. Some Muslim sects believe that April 20 is the date that "the profit" Mohammad was born-like Christmas to the Christians. It is also the police "10 code" derivation of "drug deal in progress" and slang for smoking a joint among the cannabis sub-culture. And, 2 applications: 2 of the meanings have negative connotations and hate-terrorism. 1 on the meanings is benign and carrying-smoking a joint. Submitted by Randy Emery of the Cheyenne River Sioux Tribe-Lakota on April 20,2016.
"It's 420. Lets make an impact and kill some American Jews." This statement works for both morally repugnant terrorist designations. "Hey, it's 420. lets go for a nature walk and discuss the universe then come back and eat while they Bar B Q." This statement bodes well for the Cannabis sub-culture.
