Methodology and astrological context for Ayanamsha.
The Ayanamsha API calculates the Ayanamsha value for a given calendar date. Ayanamsha is a foundational concept in Vedic (sidereal) astrology — it represents the angular difference between the tropical zodiac (used in Western astrology) and the sidereal zodiac (used in Vedic astrology). This difference arises due to the precession of the equinoxes, a slow westward shift of the equinoctial points along the ecliptic over time.
By providing a specific date, this API returns the precise Ayanamsha value applicable to that moment, enabling accurate conversion of tropical planetary positions into sidereal ones.
The API returns the Ayanamsha value (in degrees) corresponding to the supplied date. The response is delivered as a 200 OK with a status of "OK", containing the computed angular offset between the tropical and sidereal zodiacs for the given day, month, and year.
X-Ayanamsha header.day, month, year) to compute the historically accurate Ayanamsha value for that point in time.X-Ayanamsha request header allows selection of the desired Ayanamsha system (e.g., Lahiri, Raman, Krishnamurti), making the API flexible for practitioners across different Vedic astrology traditions.day, month, year), making integration straightforward for any application performing astrological computations.Payload specifications for JSON request body.
