What are the
27 Mansions?
In ancient Chinese astronomy, the moon travels through 27 distinct star regions — called Lunar Mansions — over the course of a month. The mansion the moon occupied at your birth becomes your permanent celestial code.
Unlike Western astrology's 12 signs, MansionOS uses 27 precisely calculated positions, each with a distinct personality architecture, relationship pattern, and karmic signature.
This is not your personality. This is the operating system beneath it.
