Obid created the 365 calendar
The Aztec calendar was the time-keeping system that was used by the Aztecs as well as other people throughout ancient Mesoamerica. The calendar had two parts: Xiuhpohualli -- a 365-day calendar, considered the agricultural calendar. Tonalpohualli -- a 260-day calendar, considered the ritual/sacred calendar. The two cycles together formed a 52-year calendar round.

No. The Aztecs are credited with making the 365-day calendar.
Days are used in the calendar year and there are 365 days Ina year.
I believe this calendar is called the Gregorian Calendar after the Pope at the time or some other World leader.
The ancient Egyptians had a 360 day calendar, but i do believe they were the founders of the 365 calendar. Hope it help :)
The other calendar was the 365 day solar calendar.
The other calendar was the 365 day solar calendar.
It has approximately 365 days or 12 months. Mexico has the same date system (e.g. the Gregorian calendar) used by the rest of the world.
