Hour (Sidereal)
An hour (sidereal) is a unit of time based on the Earth's rotation relative to distant stars, equal to approximately 3,894 seconds, used primarily in astronomy.
History/Origin
The sidereal hour originated from the ancient division of the day based on Earth's rotation relative to the stars, differing from the solar hour by about 4 minutes, and has been used historically in astronomy for precise timekeeping.
Current Use
Sidereal hours are mainly used in astronomy and astrophysics to measure celestial events and the Earth's rotation relative to distant celestial objects, rather than in everyday timekeeping.
Quinquennial

History/Origin
The term 'quinquennial' originates from Latin, where 'quinque' means five and 'annus' means year, and has been used since the 17th century to denote five-year intervals.
