This is an interesting read written by a community member of The Mirror of Aphrodite. Below is an excerpt from the piece:
"Everyone hears about the different prophecies on how humanity will end. From the Bible predictions of the rapture and the Antichrist, to Nostradamus's prediction of the Planet Comet, people hear theories and see evidence of our civilization coming to an end.
However, the most striking of these prophecies lies in the predictions of an ancient, but highly sophisticated Mayan calender. The deciphering and understanding of the calender is whole other story in it's own, so I'll get straight to the point. . .
The Mayan calender actually is a combination of 3 calenders. The religious calender, the solar calender, and the Long Count. For the sake of this discussion, i wont get into detail about the whole calender and just stick to the Long Count. The Long Count can record any day in history because it is supposedly the measure of days from the beginning of humanity to the end.
The number system used for the Long Count is completely different than our decimal, 10 based number system. Instead, the Mayans used 5 sets of numbers separated with a decimal. A typical Long Count number would look like this:
The first day of the Long Count is labeled 0.0.0.0.1 which is the equivalent to August 11th, 3114 BC. on our current Gregorian Calender. The Long Count calender ends at 22.214.171.124.20 which is the equivalent to December 21, 2012. Now this doesn't necessarily mean that humanity will come to an end on this date, but it is the date when the calender ends."
