Read this (the Long Count part)
If link doesn’t work, read this:
The turn of the great cycle is conjectured to have been of great significance to the Maya, but does not necessarily mark the end of the world. According to the Popol Vuh, a sacred book of the Maya, they were living in the fourth world. The Popol Vuh describes the first three worlds that the gods failed in making and the creation of the successful fourth world where men were placed. The Maya believed that the fourth world would end in catastrophe and the fifth and final world would be created that would signal the end of mankind.
The last creation ended on a long count of 188.8.131.52.0. Another 184.108.40.206.0 will occur on December 21, 2012, and it has been discussed in many New Age articles and books that this will be the end of this creation or something else entirely. However, the Maya abbreviated their long counts to just the last five vigesimal places. There were an infinitely larger number of units that were usually not shown. When the larger units were shown (notably on a monument from Coba), it is expressed as 220.127.116.11.18.104.22.168.0.0.0, where the larger units are evidently supposed to be 13s in all larger places. In this age we are only approaching 0.0.0.0.0.0.13.0.0.0.0, and the larger places are nowhere near the 13s that would match the end of the last creation.
This is confirmed by a date from Palenque, which projects forward in time to 22.214.171.124.0.0, which will occur on October 13, 4772. The Classic Period Maya obviously did not believe that the end of this age would occur in 2012. There will be a Baktun ending in 2012, a significant event being the end of a 400 year period, but not the end of the age.
Ok, i know they calculate this from mayan to gregorian, but i don’t know how they actually calculate this (even though I’m good at math). I don’t believe in this kind of trash thought up by some dead civilization that the ppl mysteriously vanished around 900 A.D. Apparently, some people asked these questions: Did the mayans thought up on the apocolyspe? How accurate is the mayan calendar? Is December 21, 2012 the end of the world? Apparently, one note, if you believe in this 2012 A.D. apocolyse stuff…you’re annoying.
I’m actually interested if some of you believe in this junk and how the calculate this (this is hard to understand).
