Jyotish

Jyotish (ज्योतिष — Sanskrit for “science of light”, the traditional term for Vedic astrology and astronomical computation) — astronomical computation engine for the AGNOS ecosystem.

Provides planetary position computation, calendar system conversions, celestial event prediction, zodiac/constellation mapping, house systems, aspect computation, and transit tracking.

Optional features

• orbital — high-fidelity orbital mechanics integration via falak.
• logging — tracing-subscriber initialization via JYOTISH_LOG env var.
