The Mayan calendar is recognized as the world's most accurate calendar, more so than the Gregorian system in use today. Its accuracy is said to be such that the Mayan calendar will need to be adjusted by only one day in 380,000 years.
There is no doubt that the current Maya Calendar Long Count has a legitimate end date of 21-12-2012. The well known Swedish Maya calendar researcher and writer states that the calendar system of the Maya has a strong spiritual aspect as well as cosmic elements to it. The Maya certainly seem to echo this is in all the information they ever share on the subject when approached.
The date February 21st, 2013 is very significant and it closely corresponds with the date of December 21st, 2012, which the ancient Maya believed to be the Earth's final day. The Gregorian calendar will end on the 16th February 2013. In accordance with this formation this is a 6 Ahau-date : the formation has been created almost precise 5 Tzolkin-cycles before the end of the Gregorian calendar.
According to Maya Elder Don Alejandro: "On March 31, 2013 the sun will be hidden for a period of 60-70 hours and this is when we shall enter the period of the Fifth Sun."
Mayan Elder Hunbatz Men comments on this imminent, ancient remembrance:
"According to the prophecies, in the year 2013 the first stage of higher understanding will begin. If we are willing to work with our subconscious, we will then be able to reclaim the information that has been impregnated in the deepest parts of our being. In this way, the ancient knowledge will rise again."
The Bible Code
According to "The Bible Code," the world will end on this date due to a collision with a meteor, asteroid, or comet. Another theory - the "Novelty Theory" - claims time itself is a "fractal wave," which will end abruptly in 2012. Even the popular television program X-Files speculated that colonization of the earth by "aliens" would occur in December 2012.
The Mayans themselves believe at the end of 2012 the serpent rope will emerge again from the center of the Milky Way, and Quetzalcoatl will return, heralding a new era at the start of 2013. Another version of the story has Quetzalcoatl sailing down on a winged ship, causing some to speculate that a UFO armada or "mother ship" could descend and take up position over earth on that date.
