The Incas, Aztecs, and Mayans all had calendars.

Explanation:

Among the Maya, chronology was determined by a complex calendrical system. The year began when the Sun crossed the zenith on July 16 and had 365 days; 364 of them were grouped into 28 weeks of 13 days each, and the new year began on 365. In addition, 360 days of the year were divided into 18 months of 20 days each. The weeks and months passed sequentially and independently of each other. Regarding scientific development, the Aztec people stood out in medicine and pharmacopoeia; Presumably, a culture so linked to warrior practices had effective cures for trauma. They also stood out in astronomy, the basis of their calendar, inheritance of the Mayan culture. They used the 365-day calendar and the 260-day calendar, also using the 52-year "calendar wheel." . The Aztecs had a cyclical conception of time, so they considered that one could predict, hence the importance of astronomical observation and the calendar. The observation of the stars was so important that this prestigious task was an obligation of Huey Tlatoani. The Inca year, consists of 360 days and is divided into 12 moons of 30 days each. Zamay Quilla (January), Little Crescent Moon, time to see the corn growing. Hatun Pucuy Quilla (February), Great Crescent Moon, time to dress loincloth. Pacha Pucuy Quilla (March), Moon of the growing flower, month of maturation of the earth. Ayrihua Quilla (April), Moon of the twin ears, harvest and rest month. Aymoray Quilla (May), Moon of the harvest, the corn is dried to be stored. Haucai Cusqui Quilla (June), potato harvest and rest, soil breakage. It consists of 18 months, 20 days each and 5 days of inactivity called nemontemi. In total, they add 365 days. The Xiuhpohualli starts on February 2 and the Nemontemi are the last days of January and the first of February.
