The natal chart
Your birth chart, from real astronomy
Enter your birth details and we compute exact planet positions with an open-source astronomy engine — no sign-up, nothing stored, everything calculated right in your browser.
As exact as you can — the rising sign shifts every two hours.
Needed for your rising sign and houses. Leave empty to compute planets only.
How to read the wheel
Never seen a natal chart before? The wheel is less cryptic than it looks — four things explain almost everything on it.
The outer ring — the twelve signs
The gold glyphs around the rim are the twelve zodiac signs, each owning a 30° slice of the sky. A planet “in” a sign simply sat inside that slice at the moment you were born. The wheel is turned so your ascendant sits at the left, nine-o'clock position — the classical orientation of every natal chart.
The inner glyphs — your planets
Each cream glyph is a planet (astrology counts the Sun and Moon among them, as the two “lights”). The small tick on the ring marks its exact degree, and the caption below the glyph repeats that degree and sign. Planets drawn close together really were close in the sky — a conjunction, which blends their themes into one.
The dashed line — ascendant and descendant
The dashed gold axis is your horizon: the ASC end marks the sign that was rising in the east — your rising sign — and the opposite end, the descendant, opens the house of partnership. This axis appears only when you enter a birth place, because it depends on geography.
Houses — where it all plays out
Signs describe how a planet behaves; houses describe where in life it shows up — money, home, career, love. We use whole-sign houses, the oldest system in the tradition: your rising sign is your entire 1st house, the next sign is the 2nd, and so on around the wheel. Each placement's house is listed in the table and in the readings.
First time with a natal chart?
What is a natal chart, in one sentence?
It is a snapshot of the sky at the minute you were born, seen from the place you were born — the position of every planet along the zodiac, read in astrology as a map of character and life themes.
Do I need my exact birth time?
For planets in signs, the date alone is usually enough — only the Moon moves fast enough to change sign within a day. But the rising sign shifts roughly every two hours, and the houses depend on it, so the closer your time, the more of the chart you unlock. Birth certificates often record it.
What should I look at first?
Your big three: the Sun (core identity), the Moon (emotional inner world) and the rising sign (the face you show). Together they explain more about why “your sign” never quite fit you than any single sign can. After that, read Venus and Mars — they describe how you love and how you pursue.
Is any of this scientific?
The astronomy is: the positions on this page are computed with a real ephemeris engine and match what a telescope would show. The meanings are not science — they are a symbolic tradition, best used as a mirror for self-reflection and conversation, not as a verdict on your life.
How do I actually use my chart?
Read each placement as a question rather than an answer: does this describe me, and where does it show up? Then compare notes — the sign profiles and compatibility guides on this site are built exactly for that next step, whether you are reading for yourself or for two.
