One question, one moment
Horary astrology casts a chart for the moment a clear question is received and understood. It does not require a birth time because it is not describing an entire life. It examines the condition and movement of the matter named in the question.
Finding the significators
The Ascendant and its ruler usually signify the person asking. The relevant house identifies the matter asked about, and that house's ruler signifies the other person, object, or outcome. A relationship question may involve the seventh house; a career question may involve the tenth. Turned houses are used when the relationship is indirect.
How perfection is judged
Judgment depends on more than finding two rulers. The astrologer examines dignity, reception, house strength, motion, applying aspects, the Moon's sequence, and whether perfection is helped or prevented through translation, collection, prohibition, frustration, or refranation.
Considerations are cautions
Traditional considerations—such as a very early Ascendant, a late Ascendant, or Saturn in the seventh—are cautions to weigh, not automatic excuses to refuse every difficult chart. They should be calculated consistently and explained without contradictory boilerplate.
Keep calculation separate
Computation and interpretation should remain separate. Software can freeze the time and place, calculate positions, houses, dignities, and aspect sequences, then pass those facts to an interpreter. Language may explain the chart; it should never invent the chart.
