Western astrology
Reads the positions of the Sun, Moon and planets against the zodiac at the moment and place you were born.
Where it comes from
Western astrology took shape in the Hellenistic Mediterranean, blending Babylonian sky-omen records with Egyptian calendars and Greek geometry. The birth chart — a map of the whole sky for one moment and place — has been its central tool for two thousand years.
What we compute from your birth
We compute real astronomical positions for the Sun, Moon and planets in the tropical zodiac, the Ascendant and houses from your exact birth time and place, and the geometric aspects between planets — the same numbers a professional ephemeris would give.
The positions and cycles are computed with real astronomy and calendar arithmetic — the interpretation never invents a number.
If it's new to you
If you know your “star sign”, you already know one factor: the Sun's zodiac position. A full chart adds the Moon, the Ascendant (the sign rising at your birth hour), eight more planets, twelve houses and their conversations — which is why two people with the same Sun sign can read so differently.
Key terms
- Sun sign
- The zodiac sign the Sun occupied at your birth — the “star sign” most people know. Core identity and vitality.
- Ascendant (rising sign)
- The sign rising on the eastern horizon at your birth moment — first impressions, instinctive style. Needs an exact birth time.
- Houses
- Twelve slices of the sky anchored to your birth place and hour; each governs a life area (self, money, kin, work…).
- Aspects
- Geometric angles between planets (conjunction, trine, square…) — how the chart's parts cooperate or clash.
- Luminaries
- The Sun and Moon — the chart's two brightest factors: conscious drive and emotional instinct.
