If you could answer this, it would clear everything up for me. Thank You
How can you change a starting date?
A starting date for a calendar is called an epoch.
The epoch of our calendar is January 1st, 1 AD, which was picked in the year 525 by the monk Dionysius Exiguus.
Meaning that at some point an epoch half a millennium earlier was established.
August 11th, 3114 BC must have had some significance for the Maya.
Anyway, the Maya calendar stops the same way as ours does on the 31st of December.
We'll just have to buy a new one.
From Wikipedia:
The Mesoamerican Long Count calendar forms the basis for a New Age belief, first forecast by José Argüelles, that a cataclysm will take place on or about December 21, 2012, a forecast that mainstream Mayanist scholars consider a misinterpretation, yet is commonly referenced in pop-culture media as the 2012 problem.
"For the ancient Maya, it was a huge celebration to make it to the end of a whole cycle," says Sandra Noble, executive director of the Foundation for the Advancement of Mesoamerican Studies, Inc. in Crystal River, Florida. To render December 21, 2012, as a doomsday or moment of cosmic shifting, she says, is "a complete fabrication and a chance for a lot of people to cash in."
So, no Maya Apocalypse.
Just search this site for 2012. Plenty of threads.

The End Of The World As We Know It, TEOTWAWKI for short, has been predicted several hundred times since antiquity.
