In the subsequent formative eras, maize cultivation and cultural traits such as a mythological and religious complex, and a vigesimal numeric system, were diffused from the Mexican cultures to the rest of the Mesoamerican culture area.

The "'Mesoamerican Long Count calendar "'is a non-repeating, vigesimal ( base-20 ) and base-18 calendar used by several pre-Columbian Mesoamerican cultures, most notably the BCE in the Proleptic Gregorian calendar.

39.
One of the more distinctive features shared among pre-Columbian Mesoamerican civilizations is the use of an extensive Maya ( whose system of Maya calendars are widely regarded as the most intricate and complex among them ) reflected the vigesimal ( base 20 ) numeral system and other numbers, such as 13 and 9.

Numbers between 20 and 99 use a vigesimal ( base-20 ) system ( comparable to 60 99 in French ) . 40, 60, and 80 are formed using 2, 3, and 4 ( respectively ), linked to the word for 20 by " m " ( a vestigial multiplicative ):
