The Calendar by @Pop_a_doc (Matt Thompsonn)

Heres a drawing I drew for Geometry class, we had to draw a mandella, and I wasnt doing to well in that class, so I put in alot of effort and got some extra credit. XP anyways, I really like this. its of the Aztec calendar, which is a more accurate calendar than the one we use to day, it doesnt need a leap year and most of the months have an equal amount of days, n stuff like that. It even had the phases of various planets in our solar system. Its attributed to the god Quetzalcoatl. Whoa, Im sorry, I turned this into a history lesson. XP
