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." .
