Combining astronomical calculations with traditional Vedic astrology rules, we built a system that generates accurate birth charts and interpretations at scale.
A Kundli, or Vedic birth chart, is calculated from the precise positions of celestial bodies at the moment and location of a person's birth. Generating an accurate Kundli requires astronomical computation for planetary positions, application of ayanamsa corrections for the sidereal zodiac, and interpretation according to classical Vedic astrological principles. Automating this process while maintaining accuracy that experienced astrologers would validate was a core technical challenge for Staarvani.
Astronomical Precision
Our computation engine uses the Swiss Ephemeris library for planetary position calculations, providing accuracy to within arc-seconds. We compute the ascendant, all nine Vedic planets, lunar nodes (Rahu and Ketu), and house cusps using multiple house systems. Time zone and daylight saving corrections are handled automatically based on the birth location, eliminating a common source of error in manual chart preparation.
From Positions to Interpretations
Raw planetary positions are just numbers. The interpretation layer applies hundreds of classical rules from texts like Brihat Parashara Hora Shastra to derive meanings from planetary placements, aspects, conjunctions, and dasha periods. Each rule has conditions, modifiers, and exceptions that our knowledge engine evaluates in context. The result is a comprehensive reading that covers personality, career, relationships, health, and timing of significant life events.
Scaling Personalised Readings
The combination of deterministic computation and AI-powered interpretation allows Staarvani to generate thousands of personalised readings daily. Each reading is unique because each birth chart is unique. The AI layer ensures that interpretations are delivered in natural, conversational language appropriate to the user's context, whether they are an astrology enthusiast asking detailed technical questions or a first-time user seeking general guidance.
