Here's a comprehensive breakdown of its history:\n\n---\n\n## Early 1970s \u2014 The Waldos and \u201c420 Louis\u201d  \n- In 1971, a group of five high school students from San Rafael High School in Marin County, California\u2014Steve Capper; Dave Reddix; Jeffrey Noel; Larry Schwartz; and Mark Gravich\u2014began meeting after school to search for a rumored, abandoned cannabis crop somewhere near Point Reyes. ([weedweek.com](https://www.weedweek.com/all-about-weed/cannabis-culture/?utm_source=openai))  \n- Their designated meeting spot was the statue of Louis Pasteur on the school grounds, at **4:20 p.m.**. They referred to this plan among themselves as \u201c420 Louis,\u201d eventually shortening it simply to \u201c420.\u201d It functioned as a private code meaning: \u201clet\u2019s get high.\u201d ([en.wikipedia.org](https://en.wikipedia.org/wiki/420_%28cannabis_culture%29?utm_source=openai))  \n\n---\n\n## Late 1970s\u20131980s \u2014 Spreading Through the Grateful Dead & Region  \n- One of the Waldos\u2019 members had a brother who worked with Grateful Dead bassist Phil Lesh. This connection helped the term \u201c420\u201d travel within the circle of Grateful Dead followers (aka Deadheads), especially around Marin County in Northern California. ([thebotanicalcenter.org](https://thebotanicalcenter.org/420-history?utm_source=openai))  \n- Over time, what started as a secret code among friends became part of regional slang and gradually made its way into cannabis culture at large. ([weedweek.com](https://www.weedweek.com/all-about-weed/cannabis-culture/?utm_source=openai))  \n\n---\n\n## Early 1990s \u2014 High Times Magazine & Public Holiday Flyers  \n- On **December 28, 1990**, flyers were distributed at a Grateful Dead concert in Oakland calling on people to gather and smoke \u201c420\u201d on April 20 at 4:20 p.m. ([weedweek.com](https://www.weedweek.com/all-about-weed/cannabis-culture/?utm_source=openai))  \n- High Times magazine published stories mentioning \u201c420\u201d in its 1991 issue, linking it explicitly to the Grateful Dead and showing it being used as more than just local slang\u2014it was becoming a symbolic time and date for cannabis consumption. ([en.wikipedia.org](https://en.wikipedia.org/wiki/420_%28cannabis_culture%29?utm_source=openai))  \n\n---\n\n## Mid-to-Late 1990s \u2014 Verification & Wider Recognition  \n- In 1998, High Times officially recognized the Waldos as the people who first used \u201c420.\u201d ([en.wikipedia.org](https://en.wikipedia.org/wiki/420_%28cannabis_culture%29?utm_source=openai))  \n- Meanwhile, various rumors had circulated\u2014some false\u2014claiming \u201c420\u201d was a police code, Bob Dylan reference, or other meanings. These have been debunked by historians and by the Waldos themselves. ([time.com](https://time.com/4292844/420-april-20-marijuana-pot-holiday-history/?utm_source=openai))  \n\n---\n\n## Modern Era \u2014 4/20 as Culture & Holiday  \n- Because American dates are formatted as month/day, **April 20** becomes 4/20\u2014thus elevating the time-based code into a full-day celebration. ([en.wikipedia.org](https://en.wikipedia.org/wiki/420_%28cannabis_culture%29?utm_source=openai))  \n- Today, 4:20 p.m. is a commonly recognized time to partake among those in cannabis culture, and April 20 is treated like an unofficial holiday\u2014marked with public gatherings, activism for legalization, promotional discounts at dispensaries, and widespread pop culture references. ([en.wikipedia.org](https://en.wikipedia.org/wiki/420_%28cannabis_culture%29?utm_source=openai))  \n\n---\n\nIf you like, I can also pull up what this looks like *globally*\u2014how 420 is observed in different places, how legal reforms intersect with the holiday, etc."
