DeLuce Topocentric Birth Chart Calculator

This calculator uses DeLuce sidereal zodiac system and topocentric coordinate system.

The DeLuce ayanamsa, developed by Robert DeLuce, is a sidereal system used by some Western astrologers. It represents an alternative approach to measuring the precession of the equinoxes and provides a different perspective on planetary positions in the zodiac.

The topocentric system calculates planetary positions relative to the observer's location on Earth's surface, rather than from Earth's center (geocentric). This results in slightly different positions, particularly for the Moon, and is preferred by some astrologers for its physical accuracy.
