Many people believe that there are five cycles of the same form a longer cycle associated with the precession of the equinoxes. This is also related to the alignment of galaxies across the galaxy when the Ecliptic equator. However, these parallels actually happens every year, but because of precession this happened on a different day. About the December 21 date, the truth is the sun touched the galaxy's equator in 1983 and will do so until 2019. Therefore, the date 2012 as the date chosen for this event is wrong.
The idea of a cycle of five formed earlier and creating flow is primarily based on the evidence because the Aztecs said that they lived in the fifth and the creation of the previous four have preceded this one. Further said that from the early Colonial period also mentioned earlier that the creation had been destroyed and has been written in the highlands of Guatemala after the Aztec century several centuries.
