Free Natal Chart Calculator

Your natal (birth) chart is a map of the sky at the moment you were born. Enter your birth details to see where the Sun, Moon and planets were, your rising sign and houses, and the key themes of your chart. Calculated with the tropical (Western) zodiac and Placidus houses.

Without a birth time we show planet signs only (no rising sign or houses). If you leave the time zone empty, your browser fills in its own zone for that date. Nothing you enter is stored.

About natal charts

A natal chart shows the positions of the Sun, Moon and planets in the twelve signs of the zodiac, and in the twelve houses, which divide the sky around your birthplace into areas of life. The rising sign (Ascendant) is the sign coming up on the eastern horizon at your birth; it changes about every two hours, so an accurate birth time matters.

This calculator uses the tropical zodiac, used in Western astrology, and the Placidus house system (equal-sized porphyry houses are used near the poles). Positions are accurate to within a fraction of a degree for the Sun and Moon, enough for interpretation. Thai and Indian astrology use the sidereal zodiac instead; see our Thai-language chart for both systems.
