The Venus Calendar. The Mayan astronomers possessed a remarkable knowledge of the movements of the planets. In particular the apparent revolution of the planet Venus was used as the basis of what we may call the Venus Calendar. The mean synodical year of Venus (nearly 584 days) is divided in the Mayan books into four parts of 236 days (morning star), 90 days (superior conjunction), 250 days (evening star), and 8 days (inferior conjunction).
