420 Day
April 20 · Level 3 · #1687 of 2238

An unofficial holiday of cannabis culture, held on 20 April, which is written 4/20 in the American style. Some people use it to gather with like-minded friends, while for others it is a day to push the debate about legalisation.
How it is celebrated: in the United States and Canada, large crowds meet in parks, and campaigners hold rallies and public events. In countries where cannabis is banned, the day is more a talking point than a party.
The number 420 is usually traced to a group of high school students in San Rafael, California, in the 1970s, who arranged to meet at 4:20 pm by a statue of Louis Pasteur.
