The Mayans were a strong empire. They made many advancements in the world. Some advancements were that they studied astronomy and agriculture. They were also very smart they noticed and thought of thinks no one would ever thing to look for or think of. They praised the sun, moon, and stars. That is way they studied studied so much. They made a lot of inventions like tear gas and the modern calender. The calender though were not correct because they did not include leap years.
The calender in my opinion is the most important advancement and now I will tell you way. The calender the Mayans made was based off the movement of the sun, moon, and stars. They all so noticed differences in the sun, moon, and star's movement and the angle of them. They saw that ever so often the sun would be in a new location on the horizon. This led them to keep track of the days which led the the making of the calender.
The calender was big advancement in the world. So that is why I believe that the Mayan calender is show important to the world today. I hope you found the page helpful.
