Mayan Calender II

The Mayan astronomers were incredible and one becomes more impressed the more one reads about them. All of their observations led to a uniquely accurate calender system. Their calender predicted more than just dates in which the world would end but solar and lunar eclipses, the summer rains, transits of venus(speaking of the this, Venus will be crossing the sun in...you guessed it 2012!), surpassing even what modern calenders can predict.
