hora

A web application for Vedic (Jyotish) astrology: it casts a birth chart (chakra), shows the grahas' positions and the panchaanga of the birth, and teaches the concepts behind them in a knowledge base. Everything is in English and Hungarian.

hora is for study and reflection, not medical, legal, financial or psychological advice; see the disclaimer.

Sources

• Methods: P.V.R. Narasimha Rao, Vedic Astrology: An Integrated Approach (where to get it). hora works through the book in order. The knowledge base explains its concepts in its own words and does not reproduce the book.
• Calculations: Swiss Ephemeris. Tests pin the values the book prints for its example charts.

Development

The toolchain and data files come from the Nix flake. Run direnv allow once, or use nix develop. Then:

cargo run -p hora-web   # http://127.0.0.1:3000
cargo test --locked

CLAUDE.md covers the layout, commands and rules, GLOSSARY.md the domain language, and docs/adr/ the decisions behind them. Report bugs and ideas in GitHub Issues.
