Day (Sidereal)
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.
Year (Leap)
A leap year is a year that has 366 days, including an extra day (February 29) added to keep the calendar year synchronized with the astronomical year.
History/Origin
The concept of adding an extra day to the calendar was introduced by the Julian calendar in 45 BC and refined by the Gregorian calendar in 1582 to correct inaccuracies in the Julian system, establishing the current rules for leap years.
Current Use
Leap years are used in the Gregorian calendar to maintain alignment with Earth's orbit around the Sun, occurring every four years with exceptions for century years not divisible by 400, ensuring calendar accuracy over long periods.
