Explorers have found the oldest Mayan calender ever discovered, and it goes way beyond Dec. 21, 2012.
The National Geographic reports that archaeologists have uncovered what they call a "Mayan megacity," complete with a vibrant mural that calculates "vast amounts of time."
"Contrary to the idea the Maya predicted the end of the world in 2012, the markings suggest dates thousands of years in the future," wrote Erik Vance for National Geographic News.
Explores found "an ancient workroom of a Maya scribe," or record-keeper. Inside the workroom were numbers on the wall with fixed tabulations. They are "tables more or less like those in the back of your chemistry book," said one of the archeologists. Some of the newly discovered calculations include dates some 7,000 years into the future, "adding to the evidence against the idea that the Maya thought the world would end in 2012 - a modern myth."
