Ancient Calendars home AncientCalendars EarlyClocks Revolution inTimekeeping The"Atomic Age" World TimeScales NIST TimeCalibration Ancient Calendars Celestial bodies-the sun, moon, planets, and stars-have provided us a reference for measuring the passage of time throughout our existence. Ancient civilizations relied upon the apparent motion of these bodies through the sky to determine seasons, months, and years. We know little about the details of timekeeping in prehistoric eras, but wherever we turn up records and artifacts, we usually discover that in every culture, some people were preoccupied with measuring and recording the passage of time. In contrast, the Mayans of Central America relied not only on the sun and moon, but also the planet Venus, to establish 260-day and 365-day calendars. Their calendars later became portions of the great Aztec calendar stones. |
