The 2012 phenomenon is a range of beliefs and proposals positing that cataclysmic or transformative events will occur in the year 2012. The forecast is based primarily on what is claimed to be the end-date of the Mayan 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.
First the facts:
Hummmm … None really.
It is true though that the Maya based their calendar on observations of the Great Rift, a band of dark dust clouds in the Milky Way to which the Sun will align with at the winter solstice of 2012 (December 21).
Just as astrology uses the positions of stars and planets to make claims of future events, the Mayans believed that accurate observation of the stars and planets would allow them to predict the future and plotted their calendars with the objective of preparing for significant world events.

Nostradamus predicted that around 2012 there would be political turmoils followed by great wars and natural disasters leading up to total destruction.
