I like when an American person asks a question and then another American answers it. First of all the guy who asked the question answered it right away what European culture is most influental in Latin American the answer is well Latin culture what else. why do you think Latin America is called that, because of mayans or aztecs ?? lol. Latin culture originated in Europe in the province of Latium some 3000 years ago. and those same people or the original Latins created Rome, one of the cities that will later shape the Roman Empire and future Latin culture as well as the course of the World. Spanish, Portuguese or Italian are just subcultures the same way that their languages all derived from Latin.
As for the calendar we use today, also the false information from the person that posted the answer previously. we didnt adopt our calendar from mayans because it was created before the people of the Old World (Europeans) even knew about the mayans or aztecs. it was the roman calendar that people use today with 2 major revisions from Gaius Julius Caesar (Julian calendar or old calendar) and later on Pope Gregory XII (Gregorian calendar or new calendar). Even the word calendar derived from the Latin word Kalendae="the called" which depicted the first day of every month.
In short some other influences have shaped the Latin American culture as such but the core of it is Latin Culture ergo Latin America. pretty much the same way that Anglo America was shaped by northwestern European culture.AnswerLatin America is mainly based on the cultures of the Spanish and Portuguese. But if you choose to include the Caribbean, it is based on strong African influences as well.
In Mexico, the Incas and Aztecs had huge civilizations. They developed their own form of writing and our calendar is based of theirs.
Other little influences are French, British, and from the Netherlands. But it is mainly Spanish and Portuguese.
