I guess no one has taken into consideration that a solar year isn't exactly 365 days, down to the exact second.
On our modern calendar, we have an exception for a leap year because we know a solar calendar is 365.24219 days and every four years, we add an extra
day to our calendar to make up that fraction of a day. And every four hundred years or so, we have to skip a leap year.
This is why the Mayan calendar expires in 2012. They made their calendar compensate for a leap year every four years, but to make it accurate to
infinity would require a huge massive calendar which would be impractical. You must keep in mind that their calendar was carved in stone.
So basically, some lucky Mayan had to carve a new calendar every four to eight hundred years. This is why their last calendar expires in 2012, not
because this ancient civilization had some mystic advanced knowledge of the end of the world but rather because these people actually understood the
math.
