Tropical Campanus Birth Chart Calculator

This calculator uses traditional tropical zodiac system and Campanus house system.

The tropical zodiac is based on the seasons and the position of the Sun at the spring equinox. This is the system used by most Western astrologers. Each sign is exactly 30 degrees, starting with Aries at the spring equinox (March 20-21).

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.
