A new discovery pushes the timeline of the 260-day Mesoamerican calendar back by several centuries. The Mesoamerican calendar is unlike anything else in the world, and the discovery sheds light into the mysterious lives of these ancient peoples. During this time, the Gulf Coast of Mexico was occupied by a mix of hunter-gatherers and increasingly sedentary cultures that began to build impressive buildings and settlements. Accurate timekeeping played a major ceremonial role in festivals and rituals, but it may have also emerged as a practical way to manage agricultural activities that were necessary to feed these growing communities.
