How is the aztec calendar alike and different from ours?

The Aztec calendar and the Gregorian calendar (the one we use most frequently today worldwide) are two different ways of representing time measurement.  

The Aztec calendar is divided into several sections that refer to the creation ages of the four elements: earth, wind, fire and water. It also has 4 rings. The first ring consists of twenty figures that constitute the days of the month. The second ring has engravings that indicate the four cardinal points (north, south, east, and west). In the third ring two fire snakes appear with the faces of the gods Xiuhtecuhtli and Tonatiuh, including the date of the creation of the sun. The last ring includes the stars of the night sky. This calendar represents the solar cycle and the ritual calendar of its culture, especially for agricultural and spiritual purposes. These cycles ordered life and at the cosmological level they show the recognition of cosmic and celestial forces that govern natural phenomena.

The Gregorian calendar is a calendar originally from Europe promoted by Pope Gregory XIII. It is based on the physical phenomena of our planet Earth, which turns around the sun. Time is considered as a measured movement of mass and energy through space. This means that the sense is centered on the physical evidence of planet Earth that moves in orbit around the sun. The meaning is fixed in the physical evidence of a materialistic perspective of reality. The Gregorian calendar originated from studies conducted between 1515 and 1578 by scientists from the University of Salamanca.

the language dates from the contacts of arabian traders with the inhabitants of the east coast of africa over many centuries. under arab influence, swahili originated as a lingua franca used by several closely related bantu-speaking tribal groups.
