2012 is sometimes claimed to be a great year of spiritual transformation (or apocalypse). Many esoteric sources interpret the completion of the thirteenth B'ak'tun cycle in the Long Count of the Maya calendar (which occurs on December 21 by the most widely held correlation) to mean there will be a major change in world order.[who?]
Accordingly, several eclectic authors claim that a major, world-changing event will take place in 2012:
The 1997 book The Bible Code claims that, according to certain algorithms of the Bible code, an asteroid or comet will collide with the Earth.
The 2006 book 2012: The Return of Quetzalcoatl by Daniel Pinchbeck discusses theories of a possible global awakening to psychic connection by the year 2012, creating a noosphere.
Other prophecies and apocalyptic writings and hypotheses for this year include:
Terence McKenna's numerological novelty theory suggests a point of singularity in which humankind will go through a great shift in consciousness.
