Get the Weednesday mug.
A rare occurence when April 20 (4/20) happens to be on a Wednesday within the year. 420 is a number synonymous with Cannabis or better known as weed. April 20 is defined as "National Get High Day". Hence the clever name, Weednesday. The mystical date of getting high is a rare one as aforementioned, only recently happening on 2016. As of the making of this definition the next Weendesday on April 20 is on the year 2022. However, when this date does fall on this certain weekday. You know shit is about to go down...
Weednesday, April 20th is the date in which blunts are passed around to celebrate the weed holiday. The weekday of April 20th, Wednesday is purely coincidental, but its better to be known as Weednesday due to April 20th having close ties with the number 420
