A real astronomical calculation
We start from your exact date, time and place of birth, and reconstruct the real position of every body at that moment, using NASA's JPL DE442 ephemeris (the numerical model used to guide space probes), not an approximate table or a generic horoscope.
The correction chain is complete: we apply all the corrections astronomers make (the time light takes to reach us, the tiny deviations caused by the Sun), then account for the slow wobble of the Earth's axis (precession and nutation), to obtain the true apparent position of the date, in the tropical zodiac. Precision reaches the arc-second.
We validate this engine against JPL Horizons, the Jet Propulsion Laboratory's reference service. It is fully free and self-contained, and covers births from 1600 to 2400.

Far more than your sun sign
Where many sites stop at the Sun, we build the entire chart: the ten planets (Sun to Pluto), the lunar Nodes, the Black Moon (Lilith) and Chiron, the "wounded healer".
We go further with the four major asteroids (Ceres, Pallas, Juno and Vesta), computed from their own ephemerides. Few consumer sites include them, and fewer still compute them from a real ephemeris rather than an approximation.
Asteroids: after Demetra George & Douglas Bloch, "Asteroid Goddesses" (1986), complemented by Martha Lang-Wescott. We present them honestly as a layer of modern psychological astrology, not as classical dogma.
The fixed stars, computed for your date
We include a curated catalogue of forty-six major stars, with their real astronomical position (the same coordinates astronomers use) and their real drift across the sky over the centuries (their proper motion).
Their longitude is not frozen on a last-century table: it is recomputed for your exact date (accounting for the slow wobble of the Earth's axis and the star's own drift), then brought into contact with your Sun, Moon and angles. Almost no consumer site does this.
Meanings after Vivian E. Robson, "The Fixed Stars and Constellations in Astrology" (1923), Reinhold Ebertin and Ptolemy, verified word for word before entering the engine.
Modern astrology, structured
We build the chart in houses (divided using Placidus, the most widely used method), with the four angles, the chart ruler (the planet that governs your ascendant), the almuten (the strongest planet in the chart), the sect (a day chart or a night chart) and the dispositor chain (which planet commands another).
Added to this: major and minor aspects, aspects to the angles, configurations (T-square, grand trine…), finer aspects and links that few sites compute (such as the quincunx or antiscia), sensitive points (Vertex, Part of Fortune and Spirit), stelliums and mutual receptions (two planets that welcome each other).
This reading extends the tradition (Ptolemy for the dignities) and modern, psychological astrology: Dane Rudhyar (humanistic astrology), Liz Greene (Jungian astrology), Richard Tarnas (archetypal approach).
An interpretation that truly speaks about you
Every reading is built from the real positions of your sky, never from generalities that could apply to anyone. What matters most in your chart is brought to the front, and the text stays faithful to your data, from the first word to the last.
Each reading is then put to the test: nothing vague that would fit anyone, nothing that locks you into a box (“you are this, full stop”), and every star or asteroid meaning is verified and sourced before it is used.
The calculation is a fact. The interpretation is a reading.
We always distinguish the two: the position of the bodies is a verifiable astronomical fact; the meaning we give them is one school's reading, which we cite. That is why no two people ever get the same analysis.
