The crown jewel of the Ancient Mayan codes was their so-called "long calendar round", or "Long Count." It started thousands of years ago in the "Age of the Gods" on 4 Ahau 8 Cumkun: August 11th, 3114 BC. It will end after 1,872,000 days around the same time that much of the World will be destroyed. The Ancient Mayans say that this will happen in the year of Katun Ahau 13: or sometime around December 21, 2012 AD.
This encoded system demonstrates their ability to calculate long cycles, and it also gives them the ability to predict cycles of destruction and the creation that follows. We already know that the Ancient Mayans had incredible accuracy and that their countdown is a coded system.
According to the Ancient Mayans code system, a Sunspot cycle equals 68,328 days; furthermore, a Mayan solar year lasts for 365 days. When you calculate the period of a Sunspot cycle using these data, it amounts to 187.2 years. And a multiple of that number - 1,872,000 - leads us to the countdown to the next Pole-Shift sometime around 2012 AD.
