What ayanamsa does ePandit use?
Explainer · reviewed August 2026
ePandit uses Lahiri (Chitrapaksha) ayanamsa for sidereal calculations. The engine sets Swiss Ephemeris sidereal mode to Lahiri before chart and panchang work. Different ayanamsas shift sidereal longitudes; we do not mix modes silently.

Why we state it on every computed page
Basis lines name ephemeris + ayanamsa + place + date so another engine can attempt verification. That is trust infrastructure, not an accuracy slogan.

ePandit checks these rules against your own birth chart, and shows which are sourced to a classical text and which are our engine's.
