What list the there Mayan eras including their beginning and ending dates?

The Mayan civilization is typically divided into three main eras: the Preclassic (or Formative) Period, which lasted from around 2000 BCE to 250 CE; the Classic Period, spanning from about 250 CE to 900 CE; and the Postclassic Period, which extended from 900 CE to the Spanish conquest in the 16th century. Each of these periods is characterized by distinct developments in architecture, writing, and society. The Preclassic saw the rise of the first Mayan cities, the Classic was marked by the height of Mayan culture and political organization, and the Postclassic experienced a decline in city-states but continued cultural activity.
