April 20, often referred to as 420, is a day celebrated by cannabis enthusiasts around the world. The date has become synonymous with marijuana culture, with many people gathering to partake in smoking or consuming cannabis products. The origins of this celebration are believed to stem from a group of high school students in California during the 1970s who would meet at 4:20 PM to smoke together. In addition to its association with cannabis, April 20 is also recognized for various events and observances. For instance, it is the birthday of notable figures such as Adolf Hitler and Queen Elizabeth II. Some communities also use this day to promote discussions about the legalization and regulation of cannabis.
