Horary astrology is one of the most precise and revealing branches of our art. It answers a specific question by casting a chart for the moment the question is understood by the astrologer. But before you cast that chart, you must follow certain rules. A poorly formed question yields a murky answer. Over three decades of practice, I have seen students rush in and waste time on charts that should never have been cast. Let us examine the discipline required.
When to Cast the Chart
The horary astrology question must be asked at a specific moment: when the querent (the person asking) truly wants an answer. The chart is cast for the time and place where the astrologer understands the question. This is a critical point. If the querent emails you at 10 AM but you read it at 5 PM, the chart is for 5 PM. The moment of reception is what matters, as William Lilly taught in Christian Astrology.
Do not cast a chart for a hypothetical or idle question. The querent must have a genuine need. If they ask "Will I marry?" but have no partner in sight, the question is premature. Wait until the matter is ripe. Bonatti in Liber Astronomiae warns against frivolous queries—they produce confused charts.
The Question Must Be Sincere and Specific
A horary astrology question must come from the heart. The querent should not test the astrologer or ask multiple questions at once. One question per chart. For example, "Will I get the job?" is fine. "Will I get the job and if not, will I find another?" is two questions. The chart cannot answer both clearly.
Also, the question must be about something that can be decided. Avoid questions about fixed events like "Will the sun rise tomorrow?"—that is not horary. The matter should be uncertain and within the realm of free will. Ptolemy in Tetrabiblos emphasizes that astrology deals with things that can be influenced, not absolute fate.
Timing and the Radical Chart
Before interpreting, judge whether the chart is "radical"—fit to be judged. The Ascendant must be in the early degrees (0-3°) or late degrees (27-29°) to be questionable. If the Ascendant is between 4° and 26°, the chart is usually radical. Also, check the Moon's via combusta (15° Libra to 15° Scorpio) and the Moon's void-of-course condition. A void Moon often means nothing will come of the matter.
If the chart is not radical, do not proceed. This is a safeguard. I have seen many beginners force a reading on a non-radical chart and get nonsense. Lilly advises to dismiss such charts and ask the querent to rephrase later.
Common Pitfalls in Horary Questions
- Asking the same question repeatedly: Once you have an answer, do not ask again. The second chart will be corrupted by the first.
- Asking for another person without their consent: Horary is for the querent's own matters. If you ask about someone else, the chart may reflect the querent's anxiety, not the other person's reality.
- Asking during a Mercury retrograde: While not a strict rule, communication is muddled. It is better to wait until Mercury is direct.
Practical Takeaway
- Cast the chart for the moment you understand the question, not when it was sent.
- Ensure the question is sincere, specific, and singular.
- Check if the chart is radical before interpreting.
- Do not repeat questions or ask on behalf of others without their involvement.
