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.
Year (Sidereal)
A sidereal year is the time it takes for the Earth to complete one orbit around the Sun relative to the fixed stars, approximately 365.25636 days.
History/Origin
The concept of the sidereal year has been used since ancient astronomy to measure Earth's orbital period relative to distant stars, predating the Gregorian calendar system.
Current Use
Sidereal years are used in astronomy to track Earth's position in its orbit relative to fixed stars, aiding in celestial coordinate calculations and star cataloging.
