2012 is claimed by some with New age beliefs to be a great year of spiritual transformation (or alternatively an apocalypse). There is disagreement among believers as to whether 2012 will see an end of civilization, or humanity will be elevated to a higher level. 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.
