Well, i did some digging into this matter. For some strange reason, this whole bit has to do with the Mayan method of keeping time. 00.00.00.00.00 where each group is changed on a 20 day cycle (so the first 5 days of the calendar would be 00.00.00.00.05, and 20 days would be 00.00.00.01.00, based on a 365 days/year system). Supposedly, they think there is something significant about 13.00.00.00.00. Well, i was particularly bored one day and decided to calculate this date for myself . . . according to historical records, most believe that this calendar's starting point was somewhere around 11 or 13 August 3114 BC (from wikipedia). Well, i calculated the days (since roughtly each grouping of zeros marks an exponent of 20 (20^4.20^3.20^2.20.00). So, i calculated the number of days from said date to Dec. 20, 2012 (or whatever it is). So 13.00.00.00.00 represents 13 X 20^4 days. So, calculating the days alone, from 11 Aug 3114 to Dec 20, 2012 is 1,872,411.25 days whereas 13 x 20^ 4 is only 2,080,000, so that number is off by a good 207,599.75 days. Thats a difference of 568.4 years . . . 13.00.00.00.00 is actually the year 2580/2581. (Calculations made with respect to 365.25 days/year to accommodate for leap years). My calculations may be off by a few days, but i think the error is pretty small. Comments or other calculations?
