The mantic calendar has proven to be particularly resistant to the onslaughts of time. Nowadays, a 'daykeeper', or divinatory priest, may stand in front of a fire, and pray in Maya to entities such as the 260 days; the cardinal directions; the ancestors of those present; important Mayan towns and archaeological sites; lakes, caves, or volcanoes; and deities taken from published editions of the Popol Vuh. People also come to these daykeepers to know about baby names, wedding dates and other special occasions.
