“If we do not require a calendar to be geared to a tropical year (earth's orbit), but only that it be geared to some part of the celestial clock, then the Maya calendar was more accurate than the Julian calendar, more accurate than the Babylonian (solar-lunar) calendar; it intermeshed the "gear wheels" of Sun, Moon and Venus, and was based on a more accurate "gear ratio" than the other calendars, repeating itself only once in 52 years.”
