Tarot birth cards, an I-Ching hexagram, a Yoruba odu, birth runes, and the numerology grid — all derived from the same birth data, each traced to the table it came from. Stars will not tell anyone what the draw means.
Illustrative. Each face links to the method and the source text; none of them carries an interpretation.
the whole engine, behind every category
93 traditional D0–D2 systems converge at cosine 0.515–0.523 across 500 charts (511 comparable pairs), engine hypotheses excluded. Engine 2.7.0. Verified 2026-09-08.
Birth cards and the court-card significator from the birthdate reduction, with the Golden Dawn and Marseille attributions kept separate.
Natal hexagram, moving lines, and the transformed hexagram — plus the hexagram behind every Human Design gate, with the Zhouyi line texts.
Principal odu with its element and signature; the full geomantic Shield Chart — Mothers, Daughters, Nephews, Witnesses, Judge — from a seed.
Solar and lunar birth runes and the full 24-stave spread by 15° arcs of the Elder Futhark.
Life path, expression, soul urge, personality, and personal-year cycles in both Pythagorean and Chaldean systems.
I-Ching casting, Flying Star Feng Shui (Xuan Kong), and Qi Men Dun Jia charts — the divinatory side of the Chinese systems.
Every draw states how it was derived — which reduction, which sequence, which arc — so you can reproduce it by hand.
Card-to-decan, rune-to-degree, odu-to-signature: each mapping cites its table. Where two lineages disagree (Golden Dawn vs. Continental tarot), both are shown rather than one chosen silently.
Stars computes what fell. What it means for the querent is the reader's work, in the reader's tradition. The engine does not narrate the spread.
Stars gives you a reproducible, sourced starting layout from birth data. Founding readers get a permanent free account for telling us where an attribution is off and which edition it should follow.
Invite-only beta. A cast endpoint is available for games, interactive fiction, and ritual tools.
