Your Big Three
The Sun describes developing identity; the Moon, instinctive needs; and the Rising sign, your orientation to life. Together they are a clear first doorway into a complex chart.

Meet your chart without getting lost in it.
We begin with the Big Three, then let you explore exact positions at your own pace. Astrology is presented as an interpretive tradition—not scientific fact or fixed destiny.
Planets
Each planet names a symbolic function—from Mercury’s thinking and language to Venus’s values and relating.
Explore planetsHouses
The twelve houses locate chart activity in areas such as home, work, partnership, vocation, and community.

Angles between planets show where different parts of the chart combine, flow, challenge, and balance one another.
Explore aspectsHow it works
Astronomy first. Interpretation second.
01 — Local time becomes an exact instant. Your IANA timezone applies the historical offset and daylight-saving rule for your birth date.
02 — The sky is calculated. A deterministic ephemeris produces tropical longitudes; time and coordinates anchor the Placidus house wheel.
03 — Your chart becomes readable. Structured editorial interpretations explain the symbols without pretending they are scientific diagnoses.

Birth chart questions
Is this birth chart free?
Yes. The complete launch chart—placements, known houses, major aspects, and standard explanations—is free and requires no account.
Why does exact birth time matter?
It determines the local horizon, so it is essential for the Ascendant and houses. The Moon may also change enough during a day to affect its exact degree or sign.
What if I do not know my birth time?
We use local noon only for sign-level planetary positions, flag lunar uncertainty, and omit the Ascendant, Midheaven, houses, and house placements rather than invent precision.
Is astrology scientifically proven?
No. Astrology is a symbolic and interpretive tradition. This site offers it for reflection and entertainment, not as scientifically validated or professional advice.
