Please read the caveat accompanying this page for important information about the current accuracy of these horoscopes. If you are interested in the material here then I suggest you read the whole book. There are also plenty of sources on the Aztec calendar and culture in general, all of which is closely related to their astrology. Try an encyclopedia as a start. I have also begun a page of discussion about the calendar, including some mathematical details which are helpful in using the calendar.
Comments are most welcome.
