Every map, one territory. Eight traditions, computed from a single birth moment. Each is good at something the others are not, and each has a limit worth stating out loud.
1 Vedic Jyotish
Sidereal zodiac, Lahiri ayanamsa, whole-sign houses. Its distinctive contribution is the Vimshottari dasha — a period clock derived from the Moon’s nakshatra at birth, which divides a life into planetary chapters with dated boundaries. Nothing in Western astrology does this job. Limit: it is the least forgiving system about birth time.
2 Western astrology
Tropical zodiac, Placidus houses. Strongest on psychological texture and on aspect patterns — the geometry between planets that describes how parts of a life pull against each other. Limit: its timing tools are looser than the dasha system, which is exactly why we run both.
3 Pythagorean numerology
Derived from name and birth date. Coarse-grained by design — it produces a handful of numbers, not a chart. Useful as a cross-check on themes the two astrologies have already raised. Limit: it does not do timing, and anyone claiming otherwise is improvising.
4 Chaldean numerology
An older letter-to-number correspondence than the Pythagorean, weighted differently. We compute both because they disagree often enough to be informative. Limit: the same as above.
5 Human Design
Tropical positions read through a 64-gate wheel, in two passes: at birth, and at the Sun’s position 88 degrees of arc earlier. Its value is practical — a decision-making strategy rather than a description. Limit: the profile line can flip on a few minutes of birth time. If your time is uncertain, we say so instead of picking one.
6 Gene Keys
The same 64 gates, read as a Shadow / Gift / Siddhi triad rather than as mechanics. Contemplative where Human Design is operational. Limit: shares Human Design’s sensitivity to birth time, and is interpretive rather than computational once the gates are fixed.
7 BaZi — Four Pillars
The Chinese system: year pillar from the solar term Li Chun rather than lunar new year, month from solar terms, day from the sexagenary cycle, hour from true solar time. It is elemental where the others are planetary, so it agrees or disagrees on genuinely independent grounds. Limit: the day pillar depends on a correctly anchored cycle; ours is hard-coded from a reliable source and verified against a canonical control before any client use.
8 Western predictive
Secondary progressions, solar arc directions, and the solar return chart. This is the Western answer to the dasha question, and the two are compared directly in every reading. Limit: the solar return needs an accurate birth time to be worth computing.
Added on request
Astrocartography — for decisions about where to live or work. Included when a reading turns on a question of place.
What birth time changes
This is the single biggest factor in what can honestly be produced for you, so it is declared explicitly in every reading.
- From a birth certificate — everything above is computable, including houses, Human Design, astrocartography and the solar return.
- Recalled from memory (±30 minutes) — houses and ascendant are reliable to the sign; we flag that the Human Design line and profile may flip.
- Unknown — houses, Human Design, Gene Keys, astrocartography and the solar return are not computable. We say so and stay with the Sun, the planets, an approximate lunar nakshatra, and the numerologies.
