About these units
Millennium (millennium)
A millennium is 1,000 years, a timescale that allows examination of civilizations, languages, religions, and climate eras. Millennia encompass major epochs such as the rise of agriculture, the development of writing, the spread of major religions, and industrialization. From the perspective of Earth science, a millennium is still a short interval—volcanoes, glaciers, and tectonic changes unfold over tens of thousands to millions of years—but it provides a useful bridge between historical and geological time. Culturally, millennia also carry symbolic weight, such as the transition to the year 2000, which triggered widespread reflection on long-term human progress.
Minute (Sidereal) (min (sidereal))
A sidereal minute is 1/60 of a sidereal hour, lasting about 59.836 seconds in solar time. This unit refines astronomical timekeeping, enabling precise tracking of star transits, celestial navigation, and long-exposure astrophotography. Sidereal minutes illustrate how deeply astronomical timing differs from civil timekeeping, demonstrating the challenges of aligning human calendars with cosmic cycles.
