What is Zi Wei Dou Shu (Purple Star Astrology)?
Zi Wei Dou Shu, commonly known as Purple Star Astrology, is a 1,000-year-old Chinese metaphysical system that maps an individual's destiny using a 12-Palace Matrix based on their exact lunar birth chart.

How does a Zi Wei Dou Shu calculator work?
A Zi Wei Dou Shu calculator works by converting an individual's Western solar birth data (Year, Month, Day, and Hour) into the traditional Chinese Lunar Calendar. It then programmatically plots 14 Major Stars and auxiliary stars into a 12-quadrant rectangular grid, calibrated to true solar time to determine planetary alignments and lifetime luck pillars.
The MetaphysicFlow calculator handles solar-to-lunar conversion and double-hour (Shi Chen) mapping automatically — no manual almanac lookup.
What is the Life Palace (Ming Gong) in Purple Star Astrology?
The Life Palace (Ming Gong) is the structural anchor of a Zi Wei Dou Shu chart, representing an individual's core persona, innate talents, and baseline destiny layout. It acts as the master operating system through which the other 11 palaces (such as Wealth, Career, and Spouse) filter reality.

How does Zi Wei Dou Shu differ from Bazi?
Zi Wei Dou Shu differs from Bazi (Four Pillars of Destiny) in its structural resolution. Bazi analyzes the macro balance of the Five Elements (Wu Xing) and Yin-Yang based on 8 characters to chart overall capacity. In contrast, Zi Wei Dou Shu operates like a detailed psychological script, mapping specific micro life events across a 12-house matrix using individual star archetypes.
