Comparison

Lahiri vs Krishnamurti Ayanamsa

Two mainstream Vedic ayanamsas, differing by roughly 6 arc-minutes. Small on paper - meaningful for precise dasha timing.

TL;DR: Astreya uses Lahiri - the government-mandated Indian standard adopted by 90%+ of modern Jyotish. Krishnamurti (KP) uses a slightly refined value focused on stellar event prediction.

Why Lahiri

In 1957 the Indian Calendar Reform Committee (chaired by Meghnad Saha) adopted the Lahiri (Chitrapaksha) ayanamsa as the national standard. Every modern Panchang (Hindu almanac) uses it. Astreya follows this consensus for full interoperability with mainstream Jyotish practitioners. See our glossary entry for the exact definition.

FAQ

What is an ayanamsa?

The angular offset between the tropical and sidereal zodiacs, caused by the ~25,800-year precession of the equinoxes. As of 2026 the value is roughly 24°.

Which ayanamsa does Astreya use?

Lahiri (Chitrapaksha) - the official standard of the Indian government since 1957 and the most widely accepted in modern Jyotish. All Astreya Vedic modules use Lahiri by default.

How is Krishnamurti (KP) different?

The Krishnamurti Paddhati system uses a slightly different ayanamsa (about 6' smaller than Lahiri) and, more importantly, a different house / sub-lord framework focused on precise event timing.

Will my chart look different?

Planetary sign placements match ~99% of the time. Nakshatra pada boundaries and dasha timing can shift by a few days to weeks - noticeable in precise event prediction, invisible in personality reading.
