Verify the birth mansion calculated from a disclosed Japanese old-calendar method, then explore its traditional themes for personality, work, decisions, and relationships. Chart facts stay separate from AI interpretation.
Japanese old-calendar 27 mansions · Birth mansion and life themes
Shukuyo is Japanese lunar mansion astrology. A reading begins with one of 27 birth mansions derived from your birth date under a stated Japanese old-calendar method. OpenFate freezes that result before AI explains themes involving temperament, work, decisions, and relationships.
Shukuyo astrology assigns one of 27 birth mansions from a Japanese old-calendar date. The calculation must be fixed before any personality or life-theme interpretation begins.
OpenFate preserves that boundary: the engine produces the chart facts, while AI organizes traditional meanings into readable, testable prompts.
A birth time, birthplace, gender, or sign-up is not needed. The recorded Gregorian date is the only personal input used for this birth-mansion profile.
New moons, principal solar terms, leap months, and the JST civil date determine the old-calendar month and day. A Chinese UTC+8 lunar-calendar result is not automatically interchangeable.
Each old-calendar month has a fixed first-day mansion. Advancing through the canonical 27-mansion cycle by the lunar day produces the birth mansion; AI does not choose it.
The Shukuyo-kyo belongs to the historical transmission of seven-day and mansion knowledge in Japan. That context matters, but it does not scientifically validate a modern birth-mansion interpretation or provide a ready-made software algorithm. OpenFate therefore states the Japanese old-calendar and 27-mansion rules it uses today.
The resulting themes can help frame questions about habits, work, decisions, and relationships. They are traditional interpretations, not proof of personality or future events.
The paid reading uses the same calculated mansion. It is designed around seven reading areas: the main answer, chart basis and boundaries, core pattern, work and decisions, relationships, a reality check, and a seven-day practice. Pay for a deeper synthesis, not a different calendar result.
Follow the editorial standards, shared validation process and the exact method used for this system.
Sites can disagree because they use different old-calendar rules, time zones or month anchors. Follow the date, convention, checks and reading in order.
Sukuyo uses only the Gregorian birth date, read in Japan Standard Time with a midnight day boundary. Birth time and place are not inputs; a date beside a new moon near midnight is flagged.
The mansion comes from the old-calendar month’s fixed starting mansion plus the old-calendar day. OpenFate uses the modern Japanese anchor table, which differs from one historical T1299 chart, and states how it resolves the 2033 ambiguity.
OpenFate publishes dated calculation comparisons and their limitations. The implementation and full test fixtures remain private. This is not third-party certification or proof of predictive accuracy.
Read a full paid reading generated from a synthetic birth date, together with the automated checks it passed. It shows the reading style and its limits, not a prediction for you.
The single-person reading is designed around seven parts. It should synthesize the same calculated mansion rather than sell a more accurate chart or repeat the free result at greater length.
New reports are checked for all seven topics, supporting observations, counterexamples, repeated filler and unfinished text. Detected failures must be corrected before delivery as a completed report. These checks do not verify every interpretation or establish predictive accuracy; saved older reports remain unchanged.
Start with the free chart. Review the reading scope and example before deciding whether a deeper interpretation is useful to you.
Free charts and paid readings use the same chart calculations. Payment provides a complete interpretation; follow-up questions are charged according to your plan. Traditional readings support self-reflection and do not guarantee future events.
Direct answers about Shukuyo, birth mansions, required birth data, and the limits of interpretation.
Shukuyo is a Japanese astrological tradition that uses an old-calendar birth date and a cycle of 27 lunar mansions. OpenFate treats it as a symbolic system, not a scientifically validated predictor.
Yes. They are common romanizations of the same Japanese term. OpenFate uses Shukuyo in English search copy while retaining Sukuyo in the route and supporting text.
No. The Japanese zodiac (eto or jūnishi) gives one of 12 animal signs by birth year. Shukuyo assigns one of 27 lunar mansions from your old-calendar birth date, so it is a separate system with its own calculation.
No. This reading uses the recorded Gregorian birth date and the disclosed Japanese old-calendar convention; it does not require a birth time or location.
No. A deterministic calendar engine derives the old-calendar date and birth mansion first. AI only explains the frozen result.
No. It can provide traditional themes and reflection prompts, but it cannot guarantee events or replace medical, legal, financial, or mental-health advice.
