Free birth chart calculator (natal chart basics)
This calculator turns your birth date, local time, UTC offset, and birth-place coordinates into the three most-requested placements in modern Western astrology: your Sun sign, Moon sign, and rising sign (Ascendant). The math uses real solar and lunar ecliptic longitudes plus the ecliptic intersection with your eastern horizon—so you get consistent, astronomy-backed tropical signs rather than a random quiz.
