The Mayan calendar dates back to around 3114 BCE. It was a complex system that included various calendar counts, such as the Tzolk'in (260-day calendar) and the Haab' (365-day calendar), as well as the Long Count calendar used for historical dates.
The Mayan calendar was created during the time of the ancient Maya civilization, with different components developed at different periods. The Long Count calendar, for example, originated around the 5th century BCE.
how far should they go? couldn't go until the end of the world!
A) No known calendar goes back that far. B) No one had invented writing by then, so there is no record.
they would go from south then come back...
The Mayan calendar does not follow the same system as the Gregorian calendar we use today. The Long Count calendar, which is often associated with the Mayans, tracks time in cycles of approximately 5,125 years. The calendar started on August 11, 3114 BCE, so the current cycle would be in the year 2021.
The Aztecs didn't make predictions about 2012 (as far as I'm aware), the whole frenzy about 2012 is due to the Mayans, who predicted the end of the world during 2012. The Mayan calendar did not predict the end of the world, it was the end of the Mayan 'Great Cycle'. Had the Mayans still been around they would just have started another one. I agree

There are a lot of Internet sites you can enter the date your last period started. It will tell you when you are due and how far along you are. Also check your symptoms in a calendar of development on the site. babycenter.com is what I used but there are others.
There is no cut off date. They can go back as far as they wish.
The special significance of the year 2012, which is, of course, the next year after this one (as I type) is that the calendar used by the ancient Mayan civilization ended at the equivalent of the year 2012 (although of course that year was not assigned the same number by the Mayans, who were not Christians and who did not count years starting with the birth of Jesus). Many people have wondered why the Mayan calendar ended in 2012, and one speculation is that the Mayan calendar ended in 2012 because the Mayans knew that life on Earth would not continue past that year. However, this is a very wild hypothesis which is not particularly believable. There is no good reason to think that 2012 is the year that life (or perhaps just the human race) will end on Earth, and there is also no good reason to think that the ancient Mayans had some secret knowledge of the future that we do not have in the 21st century. It is more likely that the reason that the Mayan calendar ended in 2012 is that, at the time that calendar was made, 2012 was so far in the future that there didn't really seem to be any need to make plans past that date.
