The LCC clicked over from [12,19,19,17,19] to [13,0,0,0,0]. What's the next day; [13,0,0,0,1] or [0,0,0,0,1]?
You could speculate a cycle of 144,000 days (394 years) restarted.
It's not far off the 400 year cycle of the Gregorian Calendar. But that's not often talked about.
But it seems clear that this date 13,0,0,0,0 did have a significance to the ancient Maya, and some modern Maya, and the start and end dates of this time cycle may well have origins that date back to the Olmecs or even earlier so worth taking note of as we experience the phenomena of crop circles in recent years and have now discovered the 'secret meaning' coded into the beginning chapters of the book of Revelations which show a link through ancient landscape geometry back to the focal point of crop circle activity in southern Britain. There have of course been quite a few crop circles which are described as 'Mayan' in design which is also worth noting in our search for the truth.
