Birth Chart Calculator

Your Sun sign is the sign most people know: it describes your core identity and what gives you energy. Your Moon sign shows your emotional needs and instincts, and your rising sign (the ascendant) is the sign that was rising on the eastern horizon when you were born — the style you show the world.

The Moon moves through a whole sign in about two and a half days, and the rising sign changes every two hours or so, which is why the date alone is not enough. With your birth time and place we can place every planet in a sign and in one of the twelve houses.

Positions are calculated with the open-source Astronomy Engine library in the tropical zodiac used in Western astrology, accurate to well within a degree. Your local time is converted using your browser’s time zone database, including historical daylight saving rules.
