 | | The Mayan "Great Cycle", or 13-Baktun cycle, which is part of the Long Count, is 1,872,000 days long, and the start date is given as August 11th 3114 BC or August 13th 3114 BC according to the 2 most popular correlations, (known as the GMT 584283 and GMT 585285 respectively). |
 | | The exception is 1 BC which is a leap year - plus the BC years have to converted to "astronomical years" by subtracting one year, to make up for the missing year zero, before calculation. |
 | | The result is 584283, the Julian Day number of the Long Count's zero day back in 3114 BC, thus confirming the end-date as December 21, 2012. |
