The Maya developed a sophisticated calendar. The ritual calendar that developed in Mesoamerica used a count of 260 days. This calendar gave each day a name, much like our days of the week. There were 20 day names, eachrepresented by a unique symbol. The days were numbered from 1 to 13. Since there are 20 day names, after the count of thirteen was reached, the next day was numbered 1 again. The 260-day or sacred count was in use throughout Mesoamerica for centuries, probably before the beginning of writing.
