Regiomontanus Geocentric Birth Chart Calculator

This calculator uses Regiomontanus house system and geocentric coordinate system.

The Regiomontanus house system, named after 15th-century astronomer Johannes Müller (Regiomontanus), is a space-based quadrant system. It is popular among Renaissance and traditional astrologers and is known for its mathematical elegance.

The geocentric system calculates planetary positions from the center of the Earth, which is the traditional and most widely used approach in Western astrology. This perspective shows the celestial bodies as they appear from Earth's center, providing the standard astrological view used by the vast majority of astrologers.
