Misinterpretation of the Mesoamerican Long Count calendar was the basis for a popular belief that a cataclysm would take place on December 21, 2012. December 21, 2012 was simply the day that the calendar went to the next “bʼakʼtun,” or group of 394 years, at Long Count 13.0.0.0.0. The date of the start of the next b’ak’tun (Long Count 14.0.0.0.0) is March 26, 2407. The date of the start of the next piktun (a complete series of 20 bʼakʼtuns), at Long Count 1.0.0.0.0.0, is October 13, 4772. The Packers have won 13 league championships, the most in NFL history, with nine pre-Super Bowl NFL titles and four Super Bowl victories.
