Colorado 4/20 guide: What’s happening when

The Front Range is gearing up for April 20: Here's a calendar of events scheduled so far

4/20, a.k.a. the stoner’s rite of spring may have passed, but events are occurring all weekend.

Here in Colorado, 4/20 has been a big deal since well before the state legalized adult-use cannabis three years ago. And given that this year’s 4/20 happens on a Thursday — two days after the federal income tax deadline and two days ahead of Earth Day — there should be all sorts of reasons to celebrate.

Trivia time: “420” reportedly became slang for cannabis-related activities decades ago, when a group of high school students in California used the term to describe their regular meet-up time after classes: 4:20 p.m., when they relaxed following what was presumably a hard day of academia.

Here’s a calendar of events currently scheduled to take place in and around the 4/20 festivities. Thanks to theKnow for 4/20 concert details — they also have details on some more concerts happening this week.


How are you celebrating #420 this year?

Send video of you celebrating to 420@TheCannabist.Co or use #420420s for a chance to be featured in a video showing up to four hundred and twenty 4/20s around the world.
