Mayan / Solar Calendar

Chichen Itza is one of the main archaeological sites on the Yucatan Peninsula, in Mexico. The name Chichen means "mouth of the well" and Itza refers to those who founded it, the Itzaes ("witches of the water") around the year 435.  Chichin Itza was sacred to the Maya peoples and a sophisticated urban center of the Mayan Civilization empire from A.D. 750 to 1200.

The pyramid at Chichen Itza, known as El Castillo, was built sometime in the 7th century and had an astronomical purpose – it is actually a solar calendar! Each of the four sides of the pyramid has 91 steps – and if you add those up, with the final step at the top of the temple platform, they total 365 – the number of days in their year – and the number of days in the solar calendar. There are other significant numbers from the Mayan calendar built into the architecture of El Castillo Pyramid at Chichen Itza!
