The highest of high holy days for marijuana smokers is coming — National 420 Day. Marijuana Day. Weed Day. Pot Day. Whatever you call it, people are smoking. The day has become synonymous with smoking weed over the years to the point where it’s basically national marijuana day. That’s only getting bigger as pot legalization becomes more and more widespread.

When is 420? What is its origin? Will there be events and festivals? Here’s everything you need to know about the cannabis-crazed day.

When is 4/20?

April 20, 2019. It falls on a Saturday this year.

What is 4/20′s origin and meaning?

April 20 actually has some horrible connotations outside of marijuana. Adolf Hitler was born on April 20, 1889. And on April 20, 1999, the Columbine High School shooting took place. Neither of those are reasons people smoke weed on 4/20, though.

A common misconception is that “420” is a police radio code for marijuana smoking. That ain’t true, either. Legend has it that a group of potheads in San Rafael, California, in the early 1970s used to get high at 4:20 p.m. in front of a statue of scientist Louis Pasteur. This led to 420 being code for anything marijuana related.

It took off from there, and by 1990 marijuana publication High Times was using the term 420 and eventually bought the website 420.com.

Are there events and festivals?

There are 4/20 festivals all over the country, with Colorado being a hotbed for events as marijuana is legal there and the culture has exploded. You can access a massive database of events and festivals here.

Is marijuana legal in New Jersey?

Not yet. When Phil Murphy became governor, it seemed recreational marijuana would be an eventuality. Murphy supports legalizing weed. The state’s legislative leaders support legalizing weed. And 60 percent of the Garden State’s residents support legalizing weed. But the historic vote in the state Legislature on a bill that would have legalized pot for adults 21 and older was called off in March, and has been rescheduled — possibly at the end of May.
