I'm curious though, you wrote "Each period of 52 years was called a Calendar Round because once the cycle was complete it would begin again the start". Do you know if the Mayan's celebrated a calendar round or did it come and go with little significance? I wonder if the general public was aware of the astrology and math behind the two calendars or did they just go about their days, much like we do?
Alas I couldn't say how much the general public knew about the calendar, but from what I've read the Mayans loved a party and tended to celebrate the end of different cycles. I expect word got around about the end of the current Calendar Round, much like everyone seems to know when this year's Easter is without knowing how it's calculated. In reference to the Long Count calendar, a scholar is quoted on Wikipedia as saying, "for the ancient Maya, it was a huge celebration to make it to the end of a whole cycle".
