This clock showing the classical Mayan period, a.d. 233-1027, is
based on the same principle as the calendar, but for only 290,160
days, or 372 Mars cycles. The Mayas also had a shorter calendar of
37,960 days representing 65 Venus cycles of 584 days, or 104 solar
years of 365 days, or 146 sacred years of 260 days. From the center,
circles indicate Mayan years, Mayan baktuns and katuns, and corresponding
years of our present calendar.
