To update what I was saying, I took a picture of the article where it says where this madness of the Mayans come from. I will try to translate it, also I upload the images, so if you can read in spanish is better.
Here it goes:
"The year 2012.
Now, just as the beginning of the actual world for the mayans of the Classic period ocurred in a registered date in the "Large Counting" as 220.127.116.11.0 - which is no other thing than 13 baak'tuunes, 0 k'atuunes, 0 tuunes, 0 winales and 0 k'ines, equivalent to august 13th of 3114 b.C. in our calendar -, december the 23th, 2012 - and not the 21st, as have been told- , is the day in which, after almost 5125 years, the complete cicle of the Large Counting goes back to 18.104.22.168.0. But this never meant the end of the world or the rise of a new era.
So, if the mayans never talked about an <<end of the world>> from where this believe came out? This belief is due to the american writer Frank Water who, in the 70's, noticed some archaelogical finds in the state of Tabasco, specifically in one mayan sricption called Monumento 6 de Tortuguero, in which the date is mentioned. Based on that, in 1975 he published his book Mystique: the Coming Sixth World of Consciusness, in which, mixing his interpretation of the mayan omens with the myth of the en of the 5th Sun of the mexicas, and some "hopis" leyends, he interpreted that date as the end of the world or <<creation of a new world>>. This book became the fisrt best seller of the new age literature, but, as we have seen, it doesn't relies on any knowledge endorsed by the academic comunity.
The Mayan people, nor the old, or currently, has been driven by fatalism, but by a deep religious reflection of their environment, which is not determined. For them, the story served to explain what had happened, to face what had been and would be."
I'm sorry if I had some bad grammatical errors or spelling errors.
