The Maya calendar, connected to networks of sacrificial shrines, is fundamental for ritual life. The rites of the 260-day cycle are treated below ('Sciences of Destiny'). Among the highland Maya, the calendrical rites of the community as a whole relate to the succession of the 365-day years, and to the so-called 'Year Bearers' in particular, that is, the four named days that can serve as new year days. Conceived as divine lords, these Year Bearers were welcomed on the mountain (one of four) which was to be their seat of power, and worshipped at each recurrence of their day in the course of the year.
