The 2012 phenomenon was a range of eschatological beliefs that cataclysmic or otherwise transformative events would occur on or around 21 December 2012. This date was regarded as the end-date of a 5,126-year-long cycle in the Mesoamerican Long Count calendar, and as such, festivities to commemorate the date took place on 21 December 2012 in the countries that were part of the Maya civilization (Mexico, Guatemala, Honduras, and El Salvador), with main events at Chichen Itza in Mexico, and Tikal in Guatemala. Various astronomical alignments and numerological formulae were proposed as pertaining to this date. A New Age interpretation held that the date marked the start of a period during which Earth and its inhabitants would undergo a positive physical or spiritual transformation, and that 21 December 2012 would mark the beginning of a new era.

Maya inscriptions occasionally mention predicted future events or commemorations that would occur on dates far beyond the completion of the 13th b'ak'tun. Most of these are in the form of "distance dates"; Long Count dates together with an additional number, known as a Distance Number, which when added to them makes a future date. On the west panel at the Temple of Inscriptions in Palenque, a section of text projects forward to the 80th 52-year Calendar Round from the coronation of the ruler K'inich Janaab' Pakal. Pakal's accession occurred on 9.9.2.4.8, equivalent to 27 July 615 AD in the proleptic Gregorian calendar. The inscription begins with Pakal's birthdate of 9.8.9.13.0 (24 March, 603 AD Gregorian) and then adds the Distance Number 10.11.10.5.8 to it, arriving at a date of 21 October 4772 AD, more than 4,000 years after Pakal's time.  Another example is Stela 1 at Coba which marks the date of creation as 13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.0.0.0.0, or nineteen units above the b'ak'tun. According to Linda Schele, these 13s represent "the starting point of a huge odometer of time", with each acting as a zero and resetting to 1 as the numbers increase. Thus this inscription anticipates the current universe lasting at least 2021x13x360 days, or roughly 2.687x1028 years; a time span equal to 2 quintillion times the age of the universe as determined by cosmologists. Others have suggested, however, that this date marks creation as having occurred after that time span.  In 2012, researchers announced the discovery of a series of Maya astronomical tables in Xultun, Guatemala which plot the movements of the Moon and other astronomical bodies over the course of 17 b'ak'tuns.

What are important dates beyond b'ak'tun 13?
