Every star has its own temperament. Once you know them, the names on the chart turn into something you can actually read.
18 Auxiliary Stars
Auxiliary Stars
Auxiliary stars work subtly but they work. They decide where a main star sends its force and how smoothly it travels, and they mark both hidden support and the challenges worth handling. Read them, and the chart turns from a static description into a direction of travel.

Frequently Asked Questions
I do not know my exact birth time. Can I still use this calculator?
Yes. Pick the closest hour range and the chart will still reflect your main traits and life themes. This tool is meant for general reference, though. For precise forecasting or an in-depth reading, consult a professional Zi Wei Dou Shu interpreter, since differences in birth location and longitude shift the true solar time slightly and that shifts the chart with it.
How does Zi Wei Dou Shu work?
Zi Wei Dou Shu builds a chart from your date and time of birth, divided into twelve palaces that each cover an area of life such as career, relationships, wealth, and health. What sets it apart from Western astrology is the emphasis: not planetary influence, but the relationships between palaces and how energy moves through different stages of life.
What can Zi Wei Dou Shu show me?
Beyond personality and natural strengths, it maps how that energy shifts over time. Major and Annual Cycles surface the lessons and turning points of each decade and each year, which helps with knowing when to push, when to adjust, and when to rest. The Four Transformations show the dynamics between people: who tends to support you, who tends to push back, and which choices can turn a situation around. Rather than predicting isolated events, it offers a way of seeing relationships, timing, and growth.
Do I need to log in or give an email address?
No. The chart is calculated in your browser as you submit, and your birth details are neither stored nor sent anywhere.
Where should I start once I have my chart?
Begin with the Life Palace, which reflects your core personality and direction. Then look at the Career and Wealth Palaces to see how those inner qualities show up outwardly through work, ambition, and how you handle money.
