Free birth chart calculator

Enter your date, time and city of birth to see your Big Three — Sun, Moon and Rising sign — plus your Life Path number. The positions are calculated with astronomical precision, including historical time zones and daylight saving time.

Why your birth time matters

The Moon changes sign every two and a half days and the Rising sign every two hours. Without a birth time we can still show your Sun sign and an approximate Moon sign, but not your Rising sign or houses.
