TaigaYes, the Aztecs created a highly accurate 365-day calendar known as the xiuhpohualli. This calendar consisted of 18 months with 20 days each, followed by a five-day period considered unlucky. They also had a separate calendar for tracking religious ceremonies and agricultural events called the tonalpohualli.

What is the difference between Gregorian calendar and Roman calendar?
The difference is the accuracy of mathematical computation of the length of the day, in essence. The Roman calendar was fairly accurate (considering the computation tools of the time, quite accurate), but over a period of many years, it was off by a period of (then) ten days. The Gregorian calendar proposal used more precise mathematics, and deduced that the calendar had lost ten days since the calendar of Rome was established. The calendar was jumped forward ten days (it's a long story). The current (Gregorian) calendar is accurate to about one day every several thousand years.
Was the Aztec calendar solar or lunar?
The Aztec calendar was a combination of both solar and ritual calendars. The solar calendar consisted of 365 days, while the ritual calendar (tonalpohualli) had 260 days. The two calendars worked together to create a more complex system for tracking time and events.
Why are there 365 days in one year?
There are either 365 or 366 days in a calendar year because it takes between 365 and 366 days for the earth to orbit the sun once.
How is the Aztec calendar different from ours?
The Aztec calendar is made up of two interlocking cycles, the 260-day Sacred Calendar and the 365-day Solar Calendar, creating a 52-year calendar round. This is different from our Gregorian calendar, which is a 365-day solar calendar with a leap year every four years. Additionally, the Aztec calendar was based on a combination of astronomical observations, religious beliefs, and mathematical calculations.
Why was the 365-day calendar invented?
The 365-day calendar was invented to track the time it takes for the Earth to orbit the sun, which is approximately 365.24 days. This calendar, known as the Gregorian calendar, helps align human activities with the seasonal changes caused by Earth's orbit.
