Background
Sidereal and tropical are two coordinate systems for dividing the ecliptic into twelve 30° signs. The sidereal zodiac is fixed to the stars; the tropical one to the equinoxes, and the two drift apart through precession.
How it works
A sidereal position equals the tropical position minus an offset called the ayanamsa. This site uses the Lahiri ayanamsa for all Vedic tools.
