National Weed Day

National Weed Day is an informal sub-culture holiday that takes place on April 20th annually, in honor of the marijuana buzz term 420.

While it is not clear how many countries have individuals that participate in celebrating this date, it is believed to number in the tens of thousands in the United States alone.
