See if you can somehow get those working calendars into the city.

Reading some more about the 260 day calendars of the Mixtec and Zapotec civilizations, it seems that these 260 days were also divided into 4 parts of 65 days.

Found out later on that the Maya also divided their 260-day calendar into "chunks" of 65 days. This is shown in the Dresden codex... 4 sections underneath the deities associated with the cardinal points have dots and "footprints". Together they form 4x5 strings of 13 dots (=4x65=260 dots/days)


We know that the Mixtec people received a name that was connected to a day out of this calendar, but was it the birthday itself, or not? Could it be that they were used to retrieve the date of conception....???

I've stumbled upon something very strange...before the beginning of this present Longcount, the day 4 ahau, 8 kumku keeps on appearing on the exact same day after 52 years: 23 august!
After 3114 BC this day keeps changing...
Well it could of course have something to do with an error in the program, but who knows?
