Campanus Birth Chart Calculator

This calculator uses the Campanus house system.

The Campanus house system, developed by 13th-century astrologer Giovanni Campano, divides the prime vertical (the circle passing through the east and west points) into twelve equal parts. It is favored by some astrologers for its unique spatial division approach.
