Background Information: Aztec Calendar

Explain to the class: 

“The Aztec Calendar was a 365 day calendar just like the one we have now. The difference is that they separated their calendar into 18 periods, or seasons. Each season contained 20 days – una veintena”. 

  • Ask: Why do you think they called these season veintenas?
  • Answer: Because they consisted of “20” days. The word veintena comes from the word veinte.

This left 5 days that were not represented on the calendar. These days were called “nemontemi”. They were the days between the old and the new year and were a time of festivals and celebration during the transition from old to new. 

The Aztec Calendar was one of the most unique and accurate calendars ever created because the source of its creation was solar and the Aztecs had none of the resources we have today to create it.

  • Ask: Can anyone tell me what solar means?
  • Answer: From the sun

During these 18 seasons, there was a time for the harvest, a time for drought, a time for rain, etc..

ACTIVITY 1 : Rock Painting
