The Long Count Mayan Calendar or the Baktun Mayan Calendar has some astonishing features for a bible student.
It is described in wikipedia at http://en.wikipedia.org/wiki/Maya_calendar
The creation date for this calendar was August 11, 3114 BC Gregorian (true solar).
It has 360 day years (Tuns) and 20 year periods called Katuns and 400 year periods (144,000 days long) called Baktuns. We know today that the sun is 400x larger than the moon and is 400x further away from the earth than the moon is. This is why the moon fits perfectly over the sun in a total solar eclipse. But how did the Mayans know this? For in scriptural terms 400x is 400 years which are 144,000 days, which is the largest time period they used in their calendar!
We also know that the Kingdom of God will be run by 144,000 heavenly kings and 144,000 earthly kings. In fact the sun and the moon declare this since the one dominates the other by 400x which is 144,000 days a king for a day in bible symbolism.
So looking at this calendar spiritually, it has heavenly knowledge within it that was not known to mankind at the time it was used by the Mayans, at least 1400 years ago.
Now the 13th Baktun, (the 13th 144,000 day period since the Mayan creation date of August 11, 3114 BC) ends on 2012December21 according to most internet sources (wikipedia has it ending on December20).
But 12x 146097 days (12x 400 true solar years) takes us from 3114August11 BC to 1687August11 AD. And then 118836 more solar days take us to 2012December21 (for a total of 144,000x 13 = 1,872,000 solar days). So if the first day of the calendar is August11, then the last day of the 13th Baktun is 2012December20 since this is an inclusive count. The reader can try this on the BLC which can be downloaded here.
So if we identify the end of the 13th Baktun with the end of Adamic mankind in this system and the 14th Baktun with the start of the full rulership of mankind in the next system by 144,000 heavenly 1NC kings and 144,000 earthly 2NC kings, then the Mayan calendar is saying that we must have mankind in this system ending on 2012Tebbeth2/3 (which is 2012December20). But we presently have the last day of Adamic man as being 2012Chislev27 and the last day of Lot as being Tebbeth7. Half way between these two is the end of the 13th Baktun. So after 222 chronological mistakes we arrive at more or less the same day for the end of mankind that the Mayans had 1400 years ago. That is too much of a coincidence.
This looks to us like an attempt by Satan to upstage the work of the last true church.
In that regard the second true church may have got as far as the LWs have presently reached chronologically. So the date of the end of adamic man might have been known before the first recorded copies of the Mayan calendar came about. In any event there is an incredible agreement between LW chronology for the end of adamic man and the Mayan calendar chronology for the end of the 13th 144,000 day age since their creation date!
Since this calendar is so full of 400x and 144,000x it may well have started with the first humans to be born again. So August11, 3114 may be the creation date of the first humans to be born again by holy spirit baptism. The Mayan calendar may therefore be a version of the calendar used in heaven.
Alternatively 3114August11 could have been the day when the demons descended or when they had their first Nephilim children with human women. In other words Satan was copying the activity of the heavenly calendar with his demonic human procreation.
So the entire period of 13 baktuns would begin with the first humans being born again as angels and end with last humans being raptured to be angels. In fact Satan would not be permitted to possess humans unless they had associated angels. So the holy spirit baptism preceded the demonic possession or demonic descent.
