Sidereal Birth Chart Calculator

What this sidereal chart calculates

Sidereal astrology aligns the zodiac with the observable constellations and differs from the tropical zodiac commonly used in Western astrology. This beta calculator applies an approximate Lahiri ayanamsa and plots four personal placements: the Sun, Moon, Venus, and Mars.

The results are intended for reflection and education. This simplified chart does not calculate the Ascendant, houses, complete planetary aspects, or a professional natal-chart interpretation.
