Maya CalendarThis Maya calendar from Yaxchilan, Mexico, bears a date equivalent to February 11, 526 C.E. The animals represent blocks of time, while the dots and profiles of gods mark numbers. The monkey (right, second from top) signals a day date. The day is defined by the god’s head in its hand, which means six, and the skull beneath the hand, which means ten: sixteen days.
