Zi Wei Dou Shu (紫微斗數), often translated as Purple Star Astrology, is an Eastern astrological system believed to have been systematized during China's Song Dynasty. "Zi Wei" refers to Polaris, the North Star — the fixed center around which all other stars revolve.
The system calculates the placement of stars across twelve life palaces based on your birth date and time. Each palace governs a domain of life: self, wealth, relationships, career, family, and more.
Where BaZi excels at reading innate character and potential, Zi Wei Dou Shu is particularly powerful for tracking how fortune shifts over time — through major cycles and annual cycles — giving you a detailed map of life's changing tides.
