birth chart calculator
calculate the natal chart behind your patterns.
A birth chart, also called a natal chart, is the astrology chart calculated from your birth date, exact birth time, and birth place. It maps your Sun, Moon, Ascendant or Rising sign, planets, houses, and aspects for the moment you were born.
This natal chart calculator turns that astrology chart into a personalized birth chart reading: 10 planets, 12 houses, major aspects, elemental balance, and an audio walkthrough that explains how those placements work together.
