Porphyrius Vesta Birth Chart Calculator

This calculator uses Porphyrius house system and Vesta (asteroid).

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.

Vesta is one of the four major asteroids and represents devotion, focus, and sacred service. In astrology, Vesta shows where we can develop laser-like focus and dedication, and how we maintain our inner flame. This calculator displays Vesta alongside the traditional planets.
