Questions & answers
How the charts are built, what happens to your data, and where this site sits among other tools.
Is my birth data stored anywhere?
No. All calculations run in your browser; your birth details are never sent to a server.
How are charts calculated?
Swiss Ephemeris (via swisseph-wasm) for the astronomy, with the Lahiri ayanamsa and whole-sign houses, following the Hora Prakash reference for derived techniques.
Why might results differ from another site?
Usually a different ayanamsa or house system, or different conventions (e.g. combustion orbs, node aspects). This site uses Lahiri + whole-sign. If you are convinced that there is a mistake, please feel free to reach out to get it fixed.
Is this professional advice?
No. The Vedic Lab is a study tool for learning the concepts of Vedic astrology, built to be approachable for beginners.
