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.
