What form of star did the Aztec calender follow to make the assumption that the world was going to end?

If it was the star of David (Pentagram) with 5 days a week, or the heptagon with its seven points for each day of the week!


Most Wicca rituals have both involved, one for the elements, and the other for keeping track of days. But the Mayan's had a special way of putting things down to accuracy, and with what astronomical star figuration related to its geometric configuration?





Make sense?|||This is the only site I could find about geometry and the Mayan calendar.

I found nothing on a star pattern/configuration.|||Its Maya not Aztec and its the whole Astronomy not just 1 star, it includes the cycles of the moon, sun, Venus, constellations and Nebula and its a calendar.
