A sidereal day is the time it takes for the Earth to complete one rotation relative to distant stars, approximately 23 hours, 56 minutes, and 4.1 seconds.
History/Origin
The concept of the sidereal day has been used in astronomy for centuries to measure Earth's rotation relative to fixed stars, differing slightly from the solar day used in everyday timekeeping.
Current Use
Sidereal days are primarily used in astronomy and celestial navigation to track the positions of stars and other celestial objects accurately.
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.
