Don't Lose Any Sleep Over It.
While I will extend this page soon, I have looked many times to see if there is a significant link in the Torah Code with the Mayan calendar that ends on December 21, 2012. To date (January 15, 2009), no such link has been found. The Mayan calendar is, of course, a pagan calendar, so it should come as no surprise that the Torah does not confirm it. The End of Days are discussed elsewhere on my site.
