<_< a year as we know it today is just a ratio of full rotations of the earth per full revolution of the earth around the sun...which is where leap year comes from.(ie 365.242 Days Per 1 Year)
the Mayan long count calendar is not a solar calendar. It does not classify time by revolutions of the earth around the sun, but rather only in full rotations of the earth. Therefore, there is no "year" in the long count calender, only days, which are further compounded into larger units by multiples of 20.
K'in = 1 Day
Uinal(or Winal) = 20 Days
Tun = 360 Days
Katun = 7,200 Days
Baktun = 144,000 Days
>_> That.
I could be wrong but I don't think December 21st was predicting the second coming of Christ...
Anyway...
Dem Christians and their Predictions,
How many times has he appeared now :P
