This is very surprising to many people because this was a very big advancement at this time period for the Maya. This process was extremely complicated, it was a process after 52 years the cycle would start up again.
These calendars were sacred, each day of the year had a specific number and point to its number. The two calendars were one of 260 days and another 365 days, like our regular year. From this it can be inferred that Mayan people and there astrology advances influenced our own calendars today. Apart from the astrology in the Mayan peoples community they had a very complex structural and engineering system based off of their homes and temples. The engineering on the Mayan temples is something of wonders to many of the best engineers in the world today. The structure of the rock and material and how it was all put together is still a mystery to many. The tools used to create such detailed designs and perfect shaped and fitted rocks were tools made by jade rock. Jade is a very strong material harder than iron and steel however, it is very rare around the world. After doing this research it shows that the Mayan were very advanced in many different aspects of their lives especially in Astronomy. To be as advanced as they were without any resources like we are us too today is
amazing.
