Since 1923, NIST radio station WWV has provided round-the-clock shortwave broadcasts of time and frequency signals. WWV’s audio signal is also offered by telephone: dial (303) 499-7111 (not toll-free). A sister station, WWVH, was established in 1948 in Hawaii, and its signal can be heard by dialing (808) 335-4363 in Hawaii. […]

With their attendant bureaucracies, formal religions, […]

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.
