Your free birth chart
A birth chart — or natal chart — is a map of where every planet stood at the exact minute and place you were born. It takes about thirty seconds, and everything else on this site builds on it.
Don't know your birth time? Use 12:00 — you'll still get your Sun, Moon and planets.
