The 2012 phenomenon comprises a range of eschatological beliefs according to which cataclysmic or transformative events will occur on 21 December 2012. This date is regarded as the end-date of a 5125-year-long cycle in the Mesoamerican Long Count calendar. Various astronomical alignments and numerological formulae have been proposed as pertaining to this date, though none have been accepted by mainstream scholarship.
A New Age interpretation of this transition is that the date marks the start of time in which Earth and its inhabitants may undergo a positive physical or spiritual transformation, and that 21 December 2012 may mark the beginning of a new era. Others suggest that the date marks the end of the world or a similar catastrophe. Scenarios suggested for the end of the world include the arrival of the next solar maximum, an interaction between Earth and the black hole at the center of the galaxy, or Earth's collision with a planet called "Nibiru".
The phenomenon has spread widely since coming to public notice, particularly on the Internet. Hundreds of thousands of websites have been posted on the subject.[95] "Ask an Astrobiologist", a NASA public outreach website, has received over 5,000 questions from the public on the subject since 2007,[120] some asking whether they should kill themselves, their children or their pets.[95] In May 2012, an Ipsos poll of 16,000 adults in 21 countries found that 8 percent had experienced fear or anxiety over the possibility of the world ending in December 2012, while an average of 10 percent agreed with the statement "the Mayan calendar, which some say 'ends' in 2012, marks the end of the world", with responses as high as 20 percent in China, 13 percent in Russia, Turkey, Japan and Korea, and 12 percent in the United States, where sales of private underground blast shelters have increased noticeably since 2009.[128][129] At least one suicide has been directly linked to fear of a 2012 apocalypse,[130] with several more anecdotally reported.[131] A panel of scientists questioned on the topic at a plenary session at the Astronomical Society of the Pacific contended that the Internet has played a substantial role in allowing this doomsday date to gain more traction than previous similar panics.[131]
Beginning in 2000, the small French village of Bugarach, population 189, began receiving visits from "esoterics"—mystic believers who have concluded that the local mountain, Pic de Bugarach, is the ideal location to weather the transformative events of 2012. In 2011, the local mayor, Jean-Pierre Delord, began voicing fears to the international press that the small town would be overwhelmed by an influx of thousands of visitors in 2012, even suggesting he may call in the army.[132][133] "We've seen a huge rise in visitors", Delord told The Independent in March 2012. "Already this year more than 20,000 people have climbed right to the top, and last year we had 10,000 hikers, which was a significant rise on the previous 12 months. They think Pic de Bugarach is 'un garage à ovnis' [a garage for UFOs]. The villagers are exasperated: the exaggerated importance of something which they see as completely removed from reality is bewildering. After 21 December, this will surely return to normal."[134] In December 2012, the French government placed 100 police and firefighters around both Bugarach and Pic de Bugarach, limiting access to potential visitors.[135]
