Maya settlements date to around 1800 B.C., centered in the tropical lowlands of what is now Guatemala.
The Maya excelled at agriculture, pottery, hieroglyph writing, calendar-making and mathematics, and left behind an astonishing amount of impressive architecture and symbolic artwork.
The Maya also made paper from tree bark and wrote in books made from this paper, known as codices; four of these codices are known to have survived. They are also credited with some of the earliest uses of chocolate and of rubber.
Guided by their religious ritual, the Maya also made significant advances in mathematics and astronomy, including the use of the zero and the development of complex calendar systems like the Calendar Round, based on 365 days, and later, the Long Count Calendar, designed to last over 5,000 years.
The Ancient Mayan Empire was able to predict weather and astrological changes with great precision thanks to their vast knowledge of astrology and math.
Although, not as popular as the Chinese calendar gender predictor, the Mayan gender prediction tool is also intriguing. The Mayans made a formula that mixed astrology, the birth month of the mother, and the mathematical element of odd and even numbers.
Mayan Gender Prediction trick is so simple, if the number of the age, and the number of the month are both odd/even, the Mayan gender predictor says it’s a girl! If the age is odd and the month is even, or vice versa, it’s a boy!
