Ayanamsa

Ayanamsa is the arc between tropical and sidereal 0° Aries at a given epoch—the precession correction that converts Western ecliptic degrees into Jyotish rashis positions.

Common definitions (Lahiri, Raman, Krishnamurti, etc.) differ by arcminutes; pick one system and stay consistent across radix, vargas-overview, and dashas-intro. This project follows a configured sidereal standard (VSOP-based) aligned with provider charts.

Without ayanamsa agreement, Moon nakshatras and lagna can shift mansion or sign. Document your ayanamsa when comparing charts with other software.
