2012 phenomenon
The 2012 phenomenon is a present-day cultural meme proposing that cataclysmic or transformative events will occur in the year 2012.[1][2] The forecast is based primarily on what is claimed to be the end-date of the Mesoamerican Long Count calendar, which is presented as lasting 5,125 years and as terminating on December 21 or 23, 2012. Arguments supporting this dating are drawn from a mixture of amateur archaeoastronomy, alternative interpretations of mythology, numerological constructions, and alleged prophecies from extraterrestrial beings.
