Info for nerds:
I use the Porphyry house system. In astrology, the house system shapes how your birth chart is divided—mapping the sky into 12 sections that rule different areas of your life (like love, career, and home). I use porphyry because it’s intuitive, not all that different from Placidus, and much easier to erect by hand (although I use software now). Placidus also has a tendency to “break” when someone was born too far away from the equator. So, I use Porphyry - it honors the personal rhythms of your chart without overcomplicating things.
