Debate all you want about what year or day you really think it is according to the Mayan calendar. Some have even argued that we may be off by up to 7 - 9 years from "translation" of the Mayan calendar, to the Gregorian. This has ABSOLUTELY NO RELEVANCE!!!

The Mayan calendar keeps a record of Venus transits, and solar eclipses. There was one solar eclipse (annular) this year on May 20, there was a Venus transit on June 6, and there will be a total solar eclipse on November 13, just as the Mayan calendar says. It is accurate. That is like the "failsafe." We can just look into the sky on certain dates to check to see if the Mayan calendar is accurate, which it is.
