What Is a Natal Chart?

Your natal chart (also called a birth chart) is a map of the heavens frozen at your first breath. Astrologers read it like a cosmic fingerprint — no two are alike, and it stays with you for life.

The three most important points are your sun sign (core identity), moon sign (emotional nature) and rising sign (outer persona). Together with the positions of all ten planets and Chiron, they paint a full picture of your strengths, challenges and purpose.

This free tool computes your chart from precise astronomical positions. A full interpretation with houses, aspects and life guidance is available when you sign in — your free result here gives you the essentials in seconds.

How It Works

We calculate your chart with the same astronomical engine trusted by professional astrologers: geocentric ecliptic longitudes for all ten planets and Chiron, the ascendant from your birth latitude and local sidereal time, whole-sign houses, and major aspects with classical orbs. Timezone handling is exact, including daylight saving.

Frequently Asked Questions

Why is my exact birth time important?✦
Your birth time determines your rising sign, which changes roughly every two hours, and with it the entire house system. Without a precise time the planets' signs are still correct, but the ascendant and houses may shift.
What do the symbols on the chart mean?✦
Each glyph is a planet: ☉ Sun, ☽ Moon, ☿ Mercury, ♀ Venus, ♂ Mars, ♃ Jupiter, ♄ Saturn, ♅ Uranus, ♆ Neptune, ♇ Pluto and ⚷ Chiron. AC marks your rising sign and MC your midheaven.
Is a natal chart really accurate?✦
The astronomical positions are exact to the second. Interpretation, however, is an art — your free result gives you the reliable facts, and the deeper meaning comes from reading the whole chart in context.
