Background

On December 13th, 2009, Highdeas^[6] user Ironlamp posted the earliest available reference to the month-long holiday. They wrote, "I just realized that in the year 2020, for the first time in 100 years, all of April will be 420, A 420 month, this only happens once a century when a year ends in 20, So when the time comes I think we should all have a month long celebration in honor of our favorite plant." The post received more than 180 comments in less than 11 years (shown below).

Developments

On April 26th, 2012, an anonymous Yahoo Answers ^[1] user who said they saw a post about the date on Tumblr. They wrote:

I saw a post on tumblr that had the caption "In the year 2020, it'll be 4/20 for a whole month"

Can anyone explain this a bit more or am I just overthinking it?

I don't really understand what the joke is here ~

Yes, that would be the month of April and the year 20 right?

But isn't it like that for any month?

For example this month with April 25 2012. It WOULD be 4/12 on april 25, 4/12 on april 26, and 4/12 on april 27 IF YOU WERE going by the month then the date. So can someone explain this because I think I'm missing something.

Yahoo Answers^[1] user PattyM answered the question, "The year number is incremented 1 on January 1st. Thus 2019 is followed by 2020 and 2020 precedes 2021. Every year has a 4th month. 4/20 is just one way of writing the date of April, 2020. In other words yes, you are overthinking the whole thing."

Over the next decade, references to "420 month" grew in popularity, particluarly in Shower Thoughts posts.
