About Ayanamsa / अयनांश के बारे में

Ayanamsa is the angular offset used to relate the tropical zodiac to a sidereal zodiac. Different sidereal systems use different reference definitions, so their values are not identical.

अयनांश उष्णकटिबंधीय (Tropical) और साइडीरियल राशि मंडल के बीच उपयोग किया जाने वाला कोणीय अंतर है। अलग-अलग प्रणालियां अलग संदर्भ बिंदु और गणना पद्धति अपनाती हैं, इसलिए उनके मान अलग हो सकते हैं।

Lahiri (Chitrapaksha)

Lahiri is the most widely used ayanamsa in Indian Vedic astrology and is the default convention used by this site's existing Moon and Sun calculators.

Raman and KP

Raman and Krishnamurti (KP) systems use different historical reference definitions. KP Old and KP New can also differ slightly from one another.

Khullar / KP Straight Line

The Khullar/KP Straight Line entry is included as a reference comparison. Its straight-line formulation is distinct from the Lahiri calculation.

Frequently Asked Questions / सामान्य प्रश्न

What is an Ayanamsa?
It is the angular difference used to convert a tropical longitude to a sidereal longitude under a chosen sidereal convention.

Which Ayanamsa should I use?
For consistency with the Sanatan Tatva Moon and Sun calculators, use Lahiri (Chitrapaksha) unless you specifically follow another astrological school.

Why do different websites show different values?
Different implementations may use different reference epochs, precession models, time standards and historical conventions.

Disclaimer: This calculator is provided for informational and traditional astrology purposes. Ayanamsa systems are convention-based astronomical/astrological reference frameworks, and different software may produce slightly different values because of implementation choices.
