The Meme of the Month Calendar is a recurring tradition within internet subcultures, particularly on platforms like Reddit and Twitter, used to archive and rank the most dominant viral trends of a specific year. It typically features a 12-slot grid representing each month, filled with the 'winner' that defined the online conversation at that time. This format gained massive popularity in the mid-2010s as a way for communities to reflect on the rapidly changing landscape of internet humor. Users utilize these calendars to debate which memes had the most impact, often sparking 'Council of Memes' discussions to finalize the official rankings for the year.
