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.
Fortnight
A fortnight is a period of two weeks, equivalent to 14 days.
History/Origin
The term 'fortnight' originates from the Old English 'fēowertīene niht', meaning 'fourteen nights'. It has been used in English since the 16th century to denote a two-week interval.
Current Use
The term 'fortnight' is still used in British English and some other English-speaking regions to specify a two-week period, especially in scheduling and planning contexts.
