How accurately Mayans were able to predict thousands years into the
future the equinoxes and precession, using different numbering system 20
and 13.
For example,Mayan calender used for Solar, 20 days x 18 moths +5
days/year

2) The Sun rises at the place every Dec 12. What is special about this one?
3) The Earth's precession is a continuous cycle. Like a circle, it has no
beginning or end.
