✦ HOW DOES IT WORK? ✦
The chart of the moment
The sky is calculated for the instant you ask. We do not look at your birth date — the moment you ask is what matters.
A 17th-century method
William Lilly's classical horary rules are applied. The rising sign and the planetary aspects are read.
Precise astronomy
Planetary positions come from the Swiss Ephemeris — an astronomy library built on NASA JPL ephemeris data — accurate to the microsecond.
A clear answer
The reading ends with a plain Yes / No / Uncertain. No ornamental riddles.
Astrum is not a prophecy but a reading of tendencies. The decision is yours.
✦ The Astrology of Questions
Horary astrology is an ancient method that answers a question by reading the sky at the moment the question is asked. Your birth date is never used: the chart is born at the instant you decide to ask and genuinely want to know. In Latin, hora means “hour” — the idea the method rests on is that when a question ripens in the mind, the sky takes a photograph of that moment.
This makes horary the most concrete branch of astrology. A birth chart describes a person's temperament and long cycles; its reading is broad, spread over years. Horary answers a single question, often with a plain Yes or No. Its margin of error is therefore visible: the event either happens or it doesn't. Being testable is a method's greatest strength.
Technically it all comes down to two planets. The 1st house of the chart stands for the person asking, and the ruler of whichever house the subject falls into stands for the thing asked about; these are the significators. Then one question is put: are those two applying to each other? An applying aspect means the connection will be made, a separating one that the window has closed, and no aspect at all that the parties never meet. The Moon counts as a third significator in every chart and reads the flow of events.
At Astrum the chart is computed for the exact moment you submit your question with Swiss Ephemeris — the astronomy library built on NASA's JPL ephemeris data — using Regiomontanus houses, as the classical horary tradition does. Yes / Yes, but / Uncertain / No is decided by code, not by the AI: the significators, the critical aspect between them, the essential dignities and the counter-testimonies are weighed in a deterministic rule engine. The AI's only job is to explain a judgment already made — which is why the same chart read twice gives the same answer.
The limits are just as plain: horary does not diagnose, does not guarantee the outcome of a case, and gives no investment advice. Very broad questions (“will my life get better?”) produce no significator, and the classical rule is not to re-ask a question simply because you disliked the answer. Astrum offers a reading of tendency, not a prophecy — the decision stays with you.
