A house division system where each zodiac sign corresponds to one entire house.
Definition
Whole Sign Houses is one of the oldest house division systems in astrology. In this method, the entire zodiac sign that contains the Ascendant becomes the 1st house, the next sign becomes the 2nd house, and so on. Each house begins at 0° of each sign, making house cusps align with sign boundaries. This system prioritizes the symbolic and archetypal qualities of the signs over precise degree measurements, offering clarity in interpretation. Edge cases arise when planets fall near sign boundaries; their house placement in Whole Sign Houses may differ from other systems such as Placidus or Equal Houses.
In a chart
In a chart using Whole Sign Houses, identify the Ascendant sign and assign it entirely to the 1st house. Each subsequent sign fills the next house consecutively. Ignore intercepted houses or uneven house sizes, as all houses span exactly 30°.
Examples
- If the Ascendant is 15° Aries, the entire sign of Aries is the 1st house, Taurus the 2nd, and so on.
- A planet at 29° Gemini will belong to the 3rd house if Gemini is the 3rd sign from the Ascendant.
History
Whole Sign Houses originated in Hellenistic astrology, around the 1st century BCE, and were widely used by early astrologers such as Ptolemy and Valens. It fell out of favor in the medieval period but has seen a resurgence in modern times.
