Tzolkin Mayan Calendar Measures Corn Life Cycle
The Tzolkin religious or ceremonial calendar of the Maya not only measures the gestation period of a human baby. It also measures the life cycle of the corn plant. One cycle of the Tzolkin lasts 260 days. In the highlands of Guatemala, 260 days marks the time between the day corn is planted and the day corn is harvested. According to John Major Jenkins, the Maya Creation Myth says that human beings are made of corn. Therefore, the human and the corn cycles coincide according to the Tzolkin.
