What are whole sign houses?

Whole sign houses is the oldest house system in Western astrology, and it works exactly how it sounds: whichever sign was rising when you were born becomes your entire first house, and each sign after that becomes the next house in order. No partial slices, no intercepted signs — just twelve clean signs mapped to twelve clean houses.

Your rising sign sets the anchor, and from there the math is simple: if your rising is Scorpio, Scorpio IS your first house, Sagittarius is your second, Capricorn is your third, and so on around the wheel. Every house covers exactly one full sign. Other systems like Placidus carve houses by degree, which means houses can vary wildly in size depending on where and when you were born — whole sign skips that complexity entirely.

The system you use isn't just a preference — it can move planets from one house to another, changing the entire story the chart tells. Whole sign is what Zodiux uses by default because it's the clearest framework for reading a planet's area of life without the distortion that latitude and time of year introduce in degree-based systems. It's also what ancient astrologers used before the alternatives existed, so a lot of classical technique was built specifically for it.
