Archaeologists claim that the Maya began counting time as of year 3114 B.C. This is called the zero year and is likened to January 1, 1 AD.
The "Calendar Round" is like two gears that inter-mesh, one smaller than the other. One of the 'gears' is called the tzolkin, or Sacred Round. The other is the haab, or Calendar Round. The smaller wheels together represent the 260-day Sacred Round; the inner wheel, with the numbers one to thirteen, meshes with the glyphs for the 20 day names on the outer wheel. A section of a large wheel represents part of the 365-day year - 18 months of 20 days each (numbered 0-19). The five days remaining at year's end were considered evil. In the diagram, the day shown is read 4 Ahua 8 Cumka. As the wheels turn in the direction of the arrows, in four days it will read 8 Kan 12 Cumku. Any day calculated on these cycles would not repeat for 18,980 days - 52 years.
The Aztec Calendar (Sun Stone) was originally named Cuauhxicalli, or Eagle Bowl, in Aztec. It was commissioned by the Aztec ruler, Axayacatl who reigned from 1469-1481 when it was common practice for each new ruler to commission not only a new Sun Stone, but also a renovation of the Templo Mayor.
The Aztec Calendar Stone - if you look closely the position of the little wheels are obvious, as are the pointers. There is no END, it's a circle that continues to go 'round and 'round in cycles that the Aztecs as followers of Maya science, believed would repeat and repeat...
Bronze Wheels. 'Calendar wheels'?
IMHO...
