vedic-astro-engine-lite 1.0.0

High-precision Vedic Astrology engine (Lite Version) with Panchanga, Varga, and Vimshottari

VedicAstroEngine Lite

VedicAstroEngine Lite is a high-precision, open-source Python library for Vedic (Hindu) Astrology. Built on top of the robust Skyfield astronomical library and NASA's JPL ephemerides, it provides core calculations for astronomical points, panchanga, and divisional charts.

🚀 Key Advantages

🛡️ Completely Free of Swiss Ephemeris (pyswisseph)

Unlike most astrological libraries, VedicAstroEngine Lite is completely independent of the Swiss Ephemeris library.

• No Licensing Headaches: Free from the restrictive dual-licensing (GPL/Commercial) of Swiss Ephemeris.
• Pure Python & NASA JPL Power: Uses NASA's DE421/DE440 ephemerides via Skyfield for state-of-the-art precision.
• Lightweight: No complex C-extensions to compile; works seamlessly across all platforms.

✅ Validated & Professional Grade

This engine has been rigorously validated and tested against professional astrological software (such as Jagannatha Hora) and standard reference libraries to ensure identical results for core calculations.

Key Features (Lite Version)

• Shodashavarga: High-resolution calculation of all 16 divisional charts (D-1 to D-60).
• Panchanga: Tithi, Vara, Nakshatra, Yoga, and Karana.
• Ashtakavarga: Core points for the 7 classical planets.
