Astrian
A reference for the symbols, not the predictions.
Astrian is a working library on astrology. Birth charts are computed from public ephemerides published by NASA's Jet Propulsion Laboratory — the same data source used by space agencies for mission planning. The result is sub-arcsecond precision for solar system positions at any date and location.
The approach
The tradition of astrology associates planetary positions with symbolic patterns — Saturn with structure and limit, Venus with beauty and exchange, Mars with drive and conflict. This library describes those associations without predicting events. A natal chart is a map, not a destiny.
Available in three languages
Astrian publishes in English, Spanish, and Portuguese. All tools, articles, and profile pages are available in all three languages from day one.
