The ancient Mayans, based on star charting, prophesied that December 21, 2012 would be the end of the world (or at least some form of universal catastrophe). Meso-American star charting started around 680 B.C. by the Olmec civilization who were recording astrological patterns in the sky and eventually shared this information with the Mayans. The Mayans had a long history of tracking the winter solstice (probably for planting crops) and creating calendars (at least 17 that we know of).
During that year, the sun reaches its solstice (a brief moment when the sun’s position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer) on December 21 for the Northern Hemisphere and June 21 for the Southern Hemisphere. That year, the solstice occurs at the moment of the conjunction of the Galactic Equator with the Milky Way. The year this occurs (in relation to our Gregorian calendar) is A.D. 2012, and happened last on August 11, 3114 B.C. With Mayan mythology teaching that our sun is a god and the Milky Way is the gateway to life and death, the Mayans concluded that this intersection in the past must have been the moment of creation. Mayan hieroglyphs seem to indicate that they believed the next intersection in 2012 would be some sort of end and a new beginning of a cycle. The Mayans also believed that the blood of human sacrifices was what powered the sun and gave it life.
All the so-called “Mayan prophecies of 2012” are nothing more than wildly speculative extrapolations, which are based on the yet uncertain interpretations by scholars of Mayan hieroglyphs. However, the truth is that apart from the astrological convergence, there is little indication that the Mayans prophesied anything specific regarding the events of this distant future. The Mayans were not prophets; they were not even able to predict their own cultural extinction. They were great mathematicians and accomplished sky watchers, but they were also a brutally violent tribal people with a primitive understanding of natural phenomena, subscribing to archaic beliefs and the barbaric practices of blood-letting and human sacrifice.
There is absolutely nothing in the Bible that would present December 21, 2012, as the end of the world. While that date is no less valid for an end-times event than any other future date, the Bible nowhere presents the astronomical phenomena the Mayans pointed to as a sign of the end times. It would seem very inconsistent of God to allow the Mayans to discover such an amazing truth while keeping the many Old Testament prophets ignorant of the timing of the events. In summary, there is absolutely no biblical evidence that the 2012 Mayan prophecy / prediction of doomsday is in any sense valid or probable.
Accepting the Mayan 2012 prophecy logically requires acceptance of the following theories: our sun is a god; the sun is powered by the blood of human sacrifice; the creation moment occurred at 3114 B.C. (despite all evidence that it happened much earlier); and the visual alignment of stars has some significance for everyday human life. Like every other false religion, the Mayan religion sought to elevate to the point of worship that which was created in place of the Creator Himself. The Bible tells us about such false worshipers: “They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator” (Romans 1:25), and “since the creation of the world God’s invisible qualities – His eternal power and divine nature – have been clearly seen, being understood from what has been made, so that men are without excuse” (Romans 1:20). To accept the Mayan 2012 prophecy also denies the clear biblical teaching about the end of the world, because Jesus told us “…of that day and hour no one knows, no, not the angels in Heaven, nor the Son, but the Father” (Mark 13:32).
2012 (MMXII) is a leap year starting on Sunday in the Gregorian calendar, and it is the current year in parts of Oceania (to the West of the International Date Line), Eastern part of Russia, and some parts of Asia. It is the 2012th year of the Common Era (CE) and Anno Domini (AD) designations; the 12th year of the 3rd millennium and of the 21st century; and the 3rd of the 2010sdecade.
The United Nations General Assembly has designated 2012 as the International Year of Cooperatives, highlighting the contribution of cooperatives to socio-economic development, in particular recognizing their impact on poverty reduction, employment generation and social integration. It has also been designated as the International Year of Sustainable Energy for All. 
There are a variety of popular beliefs about the year 2012. These beliefs range from the spiritually transformative to the apocalyptic, and center upon various interpretations of the Mesoamerican Long Count calendar. Contemporary scientists have disputed the apocalyptic versions
