On this day a rare astronomical and Mayan mythical event occurs. In astronomic terms, the Sun conjuncts the intersection of the Milky Way and the plane of the ecliptic. The Milky Way, as most of us know, extends in a general north-south direction in the night sky. The plane of the ecliptic is the track the Sun, Moon, planets and stars appear to travel in the sky, from east to west. It intersects the Milky Way at a 60 degree angle near the constellation Sagittarius.

The cosmic cross formed by the intersecting Milky Way and plane of the ecliptic was called the Sacred Tree by the Maya. The trunk of the tree, the Axis Mundi, is the Milky Way, and the main branch intersecting the tree is the plane of the ecliptic. Mythically, at sunrise on December 21, 2012, the Sun – our Father – rises to conjoin the centre of the Sacred Tree, the World Tree, the Tree of Life.
