If there's something in the air today, you've probably guessed what it is.

The date April 20 might just be a regular day for some, but to others it's known as "Weed Day" or "4/20." This is a day where pot smokers congregate  together and, well, smoke.

The day and cannabis culture itself has since become a huge part of popular culture, but many have wondered what ultimately led to this becoming a global observance of sorts.

You cannot discuss the history of 4/20 without mentioning The Waldos, who gets the credit for coining the phrase.

The aforementioned group from comprised of five San Rafael High School students -- Steve Capper, Dave Reddix, Jeffrey Noel, Larry Schwartz, and Mark Gravich -- in Marin County, California were the originators. They met by a wall so they became known as the "Waldos."

The group would meet at 4:20 p.m. by a campus statue of Louis Pasteur, a chemist, to partake in smoking. That time was chose because extracurricular activities ended at that time, so they would then say "420" to each other as code for marijuana, according to TIME.

The 4/20 observances now happens all throughout the United States and other places, but its roots will always live on by the Louis statue.
