Mayan doomsday 2012

According to the ancient Mayan civilisation, December 21, 2012, represents the end of a cycle in the Mayan long count calendar that begins in the year 3114 BC. It is the completion of 5,200 years counted in 13 baak t’uunes, a unit of time. One baak t’uune is equivalent to 144,000 days, or roughly 400 years. Doomsday believers expect a cataclysmic event to occur that day and end the world.
