Readings with rules you can understand

Astrology Guide combines deterministic astronomical calculations with reusable interpretation data. Selected written interpretations may be composed from that evidence, but interpretive presentation does not calculate or invent planetary positions, houses, aspects, event timing, or the structured astrology evidence supplied to the prose layer.

Calculate the sky

Astronomy Engine calculates apparent geocentric tropical ecliptic longitudes for each planet at the requested instant, including real longitudinal motion for retrograde status.

Interpret planet + sign

Each planet contributes a reusable core domain, while its zodiac sign supplies a reusable expression style. The deterministic engine combines those independent meanings rather than treating interpretive writing as a source of placements.

Interpret the geometry

Conjunctions, sextiles, squares, trines, and oppositions are detected from calculated geometry. Natal houses, placements, aspects, event timing, and ranked evidence are calculated and remain authoritative; written interpretation presents those results without replacing them.

Compose readable context

Structured positions and aspects are ranked into supported themes and evidence. Some generic horoscope, natal, and synastry interpretations may then be composed as readable prose from that deterministic material. Deterministic fallback content remains available where the product supports it.

How the current context is derived

This example is regenerated at least hourly. Its positions and aspects come from the same geocentric tropical calculations used by the planetary weather page; the example demonstrates the deterministic calculation layer rather than the written interpretive presentation.

Responsible interpretation

Calculation first, prose second

Written interpretation is constrained by deterministic structured astrology inputs and validation. Where applicable, deterministic fallback prose remains available if an enhanced interpretive layer is unavailable. Astrology is offered for reflection and entertainment and does not determine events, diagnose conditions, or replace professional expertise.
