Draw my Zi Wei chartWhat Zi Wei Dou Shu (Purple Star astrology) is
Zi Wei Dou Shu, often called Purple Star astrology, is a Chinese system said to have been refined during the Song dynasty. It takes its name from Zi Wei, the Emperor Star, which the tradition linked to the pole star around which the night sky turns.
Where BaZi focuses on the balance of five elements, Zi Wei Dou Shu places more than a hundred named stars into twelve palaces, each covering one area of life. Many readers find it more pictorial: you can point to a palace and see which stars sit there.
How a Zi Wei Dou Shu chart is calculated
The chart is built from your lunar birth date and the two-hour block of your birth. Your birth hour and month fix the Life palace, the year's stem gives each palace its own stem, and the element pattern of the Life palace, combined with your lunar birth day, places the Zi Wei star. The remaining major stars follow from there in fixed patterns.
Because the hour moves the Life palace and with it the whole layout, birth time matters more here than in most systems. Converting your solar date to the lunar calendar is handled automatically.
What your WORLD DESTINY Zi Wei chart includes
You get the full twelve-palace chart with all fourteen major stars, the minor stars and your birth transformations: Hua Lu, Hua Quan, Hua Ke and Hua Ji. A written reading of your Life palace comes first, followed by notes on the Career, Wealth, Spouse and Travel palaces.
The chart also marks this year's four transformations and the palaces where they land, and it highlights your current 10-year palace. As with every tradition on WORLD DESTINY, you can compare shared themes with your other charts, ask preset or free AI questions, save a PDF, or share an image card without personal details.
Reading palaces, major stars and the four transformations
Think of the twelve palaces as rooms, each standing for one theme: self, siblings, spouse, children, wealth, health, travel, friends, career, property, inner life and parents. The major stars in a room describe its character. Zi Wei is read as dignified and steady, Tian Ji as quick and thoughtful, Tai Yang as warm and outgoing, Wu Qu as practical and money-minded.
The four transformations add emphasis. Hua Lu is linked with flow and opportunity, Hua Quan with drive and authority, Hua Ke with reputation and learning, and Hua Ji with focus or areas that ask for more attention. Readers look at where each one falls rather than judging any single star alone.
Palaces are also read in groups. The Life palace is usually studied together with the palaces opposite it and at the two corners of its triangle, which in the Zi Wei layout are Travel, Wealth and Career. Stars in those three rooms are said to lend support to the Life palace, so a quiet Life palace can still be read as well backed. The same method applies to any palace you want to look at more closely, and the 10-year palace adds another layer, showing which room takes the spotlight in each decade of life.
Birth time and accuracy
A Zi Wei Dou Shu chart needs a birth time, but an approximate one is allowed. If you only know the part of the day, choose the closest option; just keep in mind that a birth near the edge of a two-hour block can shift the Life palace. Your chart is computed in your browser, and your birth data is never stored.
Like every tradition here, the reading describes how Purple Star astrology interprets a chart. It is a lens for reflection, not a guarantee of what will happen.
