It's Not Magic. It's Math.

AstroSutra's chart calculations follow defined astronomical and Jyotish rules. Planetary positions, the sidereal reference, houses, and timing periods are computed before AI writes an interpretation. This separation matters: a fluent explanation should remain tied to actual chart data rather than inventing a placement or period. The precision of a calculation does not establish the certainty of an outcome.
