How we work
Astrology is a symbolic language, not a science. We're exact about the astronomy and honest about the interpretation.
We compute first
Positions come from our own engine, built on the open-source astronomy-engine and tested against Swiss Ephemeris (the library behind astro.com), U.S. Naval Observatory data and NASA's eclipse canon.
We name the knobs
Houses depend on the house system. Every chart says which one it used, and switching shows you exactly what moves.
We say who wrote what
Readings are drafted with software assistance. Then they are either edited by our writers or checked by an automated reviewer against our voice guidelines, and each block says which.
