About Astrum

Astrum is a reading service built on horary astrology — the astrology of questions. You ask a yes/no question, the chart of the moment you asked it is calculated, judged by the classical rules, and sent to your inbox together with its reasoning.

Your birth date is never used. In horary the chart is born from the moment the question is — the whole method rests on that idea.

The site is run from İstanbul and publishes in Turkish and English. Contact: astrum.horary@gmail.com.

Most astrology content falls into one of two extremes: generic sun-sign writing on one side, and readings that pronounce judgment without ever explaining a method on the other. Very little in between answers the question how.

Horary suits that gap, because it is hard for it to hide: the answer is definite, the timeframe is limited, and when it is wrong that shows. A method being fallible does not weaken it — it makes it testable. Everything on this site is built on that assumption.

Four steps, and at each one it is clear who is doing the work:

1. The chart — Swiss Ephemeris

Planetary positions, house cusps and aspects for the exact moment of your question are computed with Swiss Ephemeris — the astronomy library built on NASA's JPL ephemeris data and used by academic and professional software. The house system is Regiomontanus: the system of the classical horary tradition, the one Lilly used.

2. The topic house

Which house the question belongs to is determined. That is a linguistic task, not an astronomical one, and it is resolved in three layers: a keyword table, a stored ruling for a question already resolved, then a classifier that sees only the sentence. If none of them can place it, you are asked — a guessed house is an answer to a question nobody asked.

3. The judgment — a rule engine

Yes / Yes, but / Uncertain / No is decided by code, not by the AI. The significators, the critical aspect between them, whether it is applying or separating, the essential dignities and the counter-testimonies are weighed in a deterministic engine. The same chart produces the same judgment every time.

4. The text — a language model

The AI has one job: to explain a judgment already made, clearly and readably. It does not make the decision, choose the timing, or find the significators. All of that comes from code and is handed to it finished.

The answer is not softened

If the chart says no, the reading says no. Bending a result to please the reader empties the method of value. About 40% of verdicts are negative, and that share has deliberately not been lowered.

If the chart cannot answer, we say so

Classical horary's considerations before judgment define the cases where a chart does not represent the question. When one of them fires, the reading does not hide it: it names the rule and explains why the answer is cautious.

No invented certainty

Checkable claims such as timing, temperament and direction are given only where the chart supports them. Where it does not, nothing is said — an invented date is worse than a vague one.

No term is used unexplained

If a reading says 'the significator is peregrine', it says immediately what that means for this question. An unexplained term does not inform the reader; it impresses them.

The guide articles on this site — what horary is, significators, the considerations before judgment, the glossary and the rest — are prepared by the Astrum Editorial Team. Each carries its last updated date.

The sources are the classical literature: chiefly William Lilly's Christian Astrology (1647), the question-astrology texts of Māshā'allāh and Abū Ma'shar from the Islamic Golden Age, and modern compilations of them. Technical claims are checked against the site's own calculation engine as they are written.

The best way to understand a method is to know its limits. The same goes for a service.

Writing this is an editorial choice, not a legal formality. A reading presented as prophecy takes the decision away from the reader. Astrum offers a reading of tendency; what you do about it is yours to decide.

Readings are paid for one at a time; payment is taken through Shopier, and your card details never reach Astrum's servers. Current prices are on the Packages page.

The only personal data we ask for is your e-mail address, used solely to deliver the reading, match your payment, and let you reach your past readings. The detail is on the Privacy & Data page.

If your reading has not arrived you can report it from I Paid, No Reading or write directly to astrum.horary@gmail.com.
