What you're looking at
A birth chart is a snapshot of the sky from where you were born, at the minute you were born. The wheel shows the twelve signs around the outside, the twelve houses inside, and each planet placed at its exact degree. Three placements carry most of the story for beginners:
- Sun — your core identity; the sign most people already know.
- Moon — your emotional weather; how you feel and recharge.
- Rising (ascendant) — the sign coming over the eastern horizon as you were born; how people first read you, and what lays out your houses.
The lines across the middle are aspects — angles between planets that astrologers read as conversations: trines flow, squares argue productively, oppositions negotiate.
Prefer to learn the shape of a chart before running your numbers? How to read a birth chart walks the same four steps the results do.
How this chart is calculatedCoordinates, house system, and astronomical checks
Every chart lists the exact time and place used, its coordinates, and its house system. Planetary positions are checked against astronomical reference data.
Questions, answered
What is a birth chart?
A birth chart (or natal chart) is a map of where every planet sat — from your point of view on Earth — at the exact moment and place you were born. It records your Sun, Moon, and Rising signs plus the positions of Mercury through Pluto across twelve houses.
Do I need my exact birth time?
For your rising sign and houses, yes — the ascendant changes roughly every two hours. Without a time we compute planets for noon: your Sun and usually your Moon are still exact to the day. Birth certificates, baby books, and parents are the usual sources.
How accurate is this calculator?
Planetary positions are computed with a professional-grade astronomical engine and are continuously tested against NASA JPL reference data to within a few hundredths of a degree — the same standard serious astrology software uses. Historical time zones, including pre-1922 local mean time and wartime clock changes, are resolved from the full IANA database.
What happens to my birth data?
The entire chart is computed in your browser; there is no server-side chart API and no account requirement. If you save a chart, it stays on this device first; optional account sync uploads saved charts only after you sign in.
Whole sign or Placidus houses — which should I pick?
Whole sign is the oldest system and the friendliest to read: each house is one full sign. Placidus is the most common modern default and divides houses by time of rising, so their sizes vary. Try both — your planets stay put; only the house boundaries move.
