This is a free traditional horary astrology chart calculator. It casts a chart for the moment and place of a question using the Swiss Ephemeris, with Regiomontanus house cusps and the seven classical planets only — no outer planets, no modern aspects, and no AI interpretation. Every value on this page is a deterministic computation.
It lists what a traditional practitioner needs to judge a horary question: essential dignities and debilities scored after Lilly, planetary speed and retrogradation, applying and separating aspects with orbs (applying aspects that cannot perfect before a sign change are flagged), combustion, cazimi and under the beams, the void-of-course Moon by the traditional definition, the classical considerations before judgment, and conjunctions to the twenty fixed stars of the Lilly/Frawley tradition.
