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.
Novennial
A novennial is a period of approximately ten years.
History/Origin
The term 'novennial' has been used historically in various contexts to denote a decade or ten-year span, though it is less common than 'decade' or 'decennial'. It originates from Latin roots 'novem' meaning nine, but in modern usage, it refers to ten years.
Current Use
Today, 'novennial' is rarely used in everyday language but may appear in scholarly or formal contexts to specify a ten-year period, especially in historical or chronological studies.
