What Is a Birth Chart Calculator?

A birth chart calculator generates a natal chart—a 360° wheel divided into 12 zodiac signs and houses—showing the positions of the Sun, Moon, planets, and other celestial points at your birth. It uses your birth date, time, and place to plot planets (e.g., Venus in Taurus) and calculate aspects (e.g., Sun square Mars). For example, a chart might reveal a Leo Sun (core identity), Cancer Moon (emotions), and Virgo Rising (outward persona). Manual calculations require ephemeris tables and time zone adjustments, which are complex. Our calculator at NiceCalculators.com automates this, delivering accurate charts with visuals.
