This calculator uses Porphyrius house system and Chiron.

The Porphyrius house system, named after the 3rd-century philosopher Porphyry, is a quadrant system that divides the space between the angles (Ascendant, IC, Descendant, MC) into three equal parts. It is one of the oldest house systems still in use today.

Chiron is a small celestial body orbiting between Saturn and Uranus, often called the "Wounded Healer" in astrology. It represents our deepest wounds and our capacity to heal ourselves and others through understanding those wounds. This calculator displays Chiron alongside the traditional planets.
