Thousands of ballcourts are known throughout Mesoamerica, as they are usually a main component of public architecture at mostly high-ranking archaeological sites. These buildings appear in different designs and layouts and were deeply tied to politics, religion, sacred belief, ritual, ceremonies, and sport. Considering that the construction of public buildings followed well-established architectural standards in accordance with social norms and religious concepts, I hypothesize that ballcourts were designed using closed polygon layouts with lengths and areas that displayed significant worldview numbers and time counts. Analysis of the layouts of 28 ballcourts from 17 archaeological sites indicates that Mesoamericans intentionally plotted short- and long-term annual and ritual calendric counts, and lunar and Venus synodic cycles. It is concluded that these buildings hosted public events to commemorate the completion or beginning of a new time cycle and to honor the related deities for whom they were built.
