Mayan Astrology
From Astrology Wikia
It is difficult for a non-Mayan to appreciate how completely astrology pervades Mayan thought and day-to-day activities. Mayan religion, philosophy, jurisprudence, medicine, agriculture, hunting, intimate relationships, etc. etc. completely revolve around a 260-day almanac known as the Chol Qij, (sometimes called Tzolkin) or count of days (see the Mayan calendar article for detailed information]]. The Chol Qij consists of twenty naguals which can be thought of as archetypes roughly analogous in significance to our twelve zodiacal signs; except they are considered to be alive and petitionable. A nagual is preceded by a numerical coefficient ranging from one to thirteen which modifies its underlying meaning. Thus twenty naguals x 13 numerical coefficients = 260 days. The origin of this numerical system is unknown but some Mayans believe that the number comes from the fact that 260 days is considered the normal human gestation period.
