Lahiri Ayanamsa Calculator
Get the Lahiri (Chitrapaksha) ayanamsa for any date in degrees, minutes and seconds. It's the gap between the Western tropical zodiac and the Vedic sidereal one.
What ayanamsa is
The Earth's axis wobbles slowly (precession), so the point where the Sun crosses the equator in March drifts backwards against the stars by about 50.3 arcseconds a year. The tropical zodiac follows that point; the sidereal zodiac stays fixed to the stars. The ayanamsa is the angle between them. Subtract it from a tropical longitude to get the Vedic one.
Lahiri (also called Chitrapaksha) is the ayanamsa adopted by the Indian government's calendar reform committee in 1955 and used by most Indian panchangs. We use 23.857092° at J2000 plus general precession, and add nutation for the "true" value used with apparent planet positions. That's why the true value can differ from the mean by up to about 17 arcseconds.
