Show the math — how the chart is calculated
Positions are computed with a precise astronomical ephemeris (astronomy-engine, validated against published reference charts to within an arcminute for the planets and exact for the Ascendant). Houses use Placidus when a birth time is known and are omitted — never estimated — when it isn’t.
The calculation always runs first, deterministically. The written interpretation receives the finished chart and today’s transits as structured data and is not permitted to invent a placement, a degree or a date. Every reading records the engine version and prompt version it was produced with.
Astrology is offered here as reflection and entertainment, not as science or prediction, and never as medical, legal, financial or psychological advice.
