1. Purple Star Astrology, Defined
"Purple Star Astrology" is the standard English name for Zi Wei Dou Shu (紫微斗數) — a Chinese astrological system that maps birth data onto a 12-house chart populated by stars, rather than the planets used in Western astrology. It is entirely free to calculate here: enter your birth date, time, and gender to generate your own chart with the purple star astrology calculator on the homepage.
2. The Stars in Purple Star Astrology
There are 14 major purple star astrology stars — Zi Wei (Emperor), Tian Ji (Strategist), Tai Yang (Sun), Wu Qu (General), Tian Tong (Blessing), Lian Zhen (Judge), Tian Fu (Treasury), Tai Yin (Moon), Tan Lang (Greedy Wolf), Ju Men (Gate), Tian Xiang (Minister), Tian Liang (Elder), Qi Sha (Seven Killings), and Po Jun (Army Breaker) — plus dozens of minor and supporting stars that add nuance to a placement.
3. Chinese Purple Star Astrology, Free and In English
This calculator uses the same traditional Chinese lunar-calendar calculation used by professional software, but presents every star, palace, and transformation with its English name and pinyin alongside the Chinese characters — so you get an authentic chinese purple star astrology free reading, readable without any Chinese language background.
4. How to Read Your Purple Star Astrology Chart
Start with the Life Palace (命宮) — whichever major star sits there sets the tone for your core personality. Then check the Spouse Palace for relationship patterns, the Career Palace for professional direction, and the Wealth Palace for how money tends to move through your life. Each palace page on this site (/palaces/) breaks down what to look for.
