Explain the Mayan calendar to me.

Specifically, how does it work? Why is it revered as a time piece? Isn’t it supposedly especially accurate? Until then, I’ll try and uncrack military time.

The Mayan Civil Calendar was 365 days long (18 months of 20 days, plus a 5-day bad luck week). However, the Mayans actually had three Calendars - the civil calendar, the divine calendar and the Long Count.

I tried to start to explain it but honestly it’s complicated. Read this.
