I know more about the Aztecs (Mexica of Tenochtitlan in particular) than the Olmecs, etc., so please forgive the question: is this using the 260 day calendar exclusively, or is it in conjunction with the 365 day calendar?

(For those who aren't familiar, the Aztecs used the 365 day solar calendar and 260 day sacred calendar at the same time, with them lining up every 52 years.)

The 260 days calendar is exclusively for ritual purposes. It's used in conjunction with other astronomical calendars: Solar calendar of 360 days (plus 5 bad days...) Moon calendar, and also a Venus calendar (this one quite important!)

And other bigger cycles.

The Dresden codex it's a beautiful and rich ritual calendar, really interesting.

I asked the question because the article is looking at Preclassic, not Postclassic. Dresden codex is Postclassic.
