According to an article in the Guardian, when modern day Mayans living in the Yukatan peninsula were questioned about the end of the world prediction most were unaware of it! 

David Stuart, a noted Mayan specialist says, "no Maya text – ancient, colonial or modern – ever predicted the end of time or the end of the world."

Stuart and Mayan scholar Carl Callaway say "that December 21, 2013, marks a special occasion in the ancient Mayan calendar...(and) that December 21, 2012, marks the end of the 13th Bak'tun period. The close of each Bak'tun period occurs approximately once every 5125 years.

The last time a Bak'tun period ended was at the beginning of the current Maya era in August 11, 3114 B.C. making December 21, 2013, the dawn of a new period" 

"The doomsday scenario is simply a human concoction that has nothing to do with what Mayans believed in or predicted."
