Free Zi Wei Chart Guide: Create Your First Purple Star Astrology Chart in 3 Steps
If you want to understand your natal pattern, personality structure, and life timing, the best starting point is a free Zi Wei Dou Shu chart. You do not need to pay anything to generate the chart itself. With accurate birth data, you can create a full chart in a few minutes and begin learning how the system works.
This guide walks you through the first chart generation process from zero: what data to prepare, what the chart structure means, where to find your Life Palace, and how to begin reading the most important information.
What Is Zi Wei Chart Calculation?
Chart calculation is the process of converting your birth data into a Zi Wei Dou Shu natal chart.
A Zi Wei chart is a square chart made of twelve palaces. Each palace represents a different life area, such as career, relationships, health, money, assets, and inner life. The calculation uses lunar-calendar birth year, month, day, and hour to place Zi Wei, the fourteen major stars, and many auxiliary stars into those twelve palaces.
Because every person has a different birth time, the star distribution also changes. That is why Zi Wei Dou Shu can produce a highly specific chart structure for each person.
Traditionally, chart calculation required many tables and manual rules. It was time-consuming and easy to get wrong. With an online chart generator, you can enter your birth data and receive a complete chart within seconds.
What Do You Need Before Generating a Chart?
You need three basic pieces of information. The more precise they are, the more useful the chart becomes.
| Required data | Meaning | Notes |
|---|---|---|
| Birth date | Gregorian year, month, and day are enough; the system can convert to lunar date | Confirm whether an older family record uses lunar or Gregorian date |
| Birth time | Zi Wei uses twelve two-hour birth periods | This is the most important variable; one birth-hour difference can change the whole chart |
| Sex | Biological sex | Used to calculate the direction of major cycles |
Twelve Birth-Hour Table
| Branch hour | Time range | Branch hour | Time range |
|---|---|---|---|
| Zi | 23:00 - 01:00 | Wu | 11:00 - 13:00 |
| Chou | 01:00 - 03:00 | Wei | 13:00 - 15:00 |
| Yin | 03:00 - 05:00 | Shen | 15:00 - 17:00 |
| Mao | 05:00 - 07:00 | You | 17:00 - 19:00 |
| Chen | 07:00 - 09:00 | Xu | 19:00 - 21:00 |
| Si | 09:00 - 11:00 | Hai | 21:00 - 23:00 |
If you are not sure about your birth hour, read True Solar Time in Zi Wei Dou Shu. Birthplace longitude, daylight saving time, and boundary times can matter.
Step 1: Enter Your Birth Data
Open the free Zi Wei chart generator, then follow these steps:
- Select your birth date. Enter your Gregorian birth date. The system handles lunar conversion.
- Select your birth hour. Choose the correct two-hour branch period.
- Select sex. This is needed for major-cycle direction.
- Generate the chart. The system will calculate your full natal chart.
After calculation, you will see a square chart divided into twelve sections. Each section contains palace names and star names. This is your Zi Wei natal chart.
Step 2: Understand the Basic Chart Structure
The twelve boxes on the chart are the twelve palaces. Each palace governs one life domain.

Step 3: Find the Main Star in Your Life Palace
Once you find the Life Palace, look at the major star or stars inside it. The fourteen major stars are the core actors in Zi Wei Dou Shu, and the Life Palace main star sets your basic temperament.
Fourteen Major Stars at a Glance
| Group | Star | Core quality |
|---|---|---|
| Northern Dipper | Zi Wei | Leadership, dignity, command |
| Northern Dipper | Tan Lang | Desire, social charm, versatility |
| Northern Dipper | Wu Qu | Decisiveness, practicality, finance |
| Northern Dipper | Ju Men | Analysis, speech, debate |
| Northern Dipper | Lian Zhen | Sensitivity, complexity, artistic quality |
| Northern Dipper | Po Jun | Initiative, change, rebuilding |
| Southern Dipper | Tian Fu | Stability, tolerance, preservation |
| Southern Dipper | Tian Ji | Intelligence, change, planning |
| Southern Dipper | Tian Xiang | Coordination, service, social grace |
| Southern Dipper | Tian Liang | Integrity, protection, elder quality |

| Southern Dipper | Qi Sha | Courage, independence, general-star force |
| Central | Tai Yang | Brightness, giving, public spirit |
| Central | Tai Yin | Subtlety, inwardness, wealth and property |
If your Life Palace has no major star, it is called an empty palace. In that case, use the opposite Travel Palace for reference, but remember that borrowed influence is weaker than a star sitting directly in the palace.

Free Chart vs Paid Interpretation
Many people ask what the difference is between a free chart and a paid interpretation. The difference is not the chart itself. The difference is the level of explanation.
| Item | Free chart | Paid AI interpretation |
|---|---|---|
| Chart generation | Full twelve-palace star distribution | Same chart data |
| Basic information | Palace names, major stars, transformations | Same chart data |
| Personality analysis | You read and compare by yourself | Personalized analysis based on the full chart |

| Best for | Learners who want raw chart data | Users who want faster, guided understanding |
The free chart gives you the raw data, like a health report. A paid interpretation explains the report and helps you identify what matters.
For beginners, it is best to start with the free chart and learning articles. Build the basic framework first, then decide whether you need deeper interpretation.
How Should Beginners Read the Result?
Do not try to understand everything at once. Read the chart in a simple order.
Four Beginner Steps
| Step | What to observe | Learning goal |
|---|---|---|
| 1 | Which major star is in the Life Palace? | Understand core personality |
| 2 | What appears in the Life Palace San Fang Si Zheng? | Understand the basic career and money structure |
| 3 | What appears in the Spouse Palace? | Understand relationship pattern and partner preference |
| 4 | Where are the Four Transformations? | Understand the dynamic flow of the chart |
The Four Transformations are the most important dynamic layer. Hua Lu shows resource and smoothness, Hua Quan shows control and ambition, Hua Ke shows recognition and noble help, and Hua Ji shows friction or the area that needs careful handling.

FAQ
Does Zi Wei chart generation cost money?
No. Chart generation itself can be free. The free chart generator provides full chart calculation, including major stars, auxiliary stars, Four Transformations, major cycles, and annual chart display.
What if I do not know my birth hour?
Birth hour is the most important variable in Zi Wei Dou Shu. If you are unsure:
- Check your birth certificate or official birth record.
- Ask parents or older relatives.
- Review true solar time correction for birthplace and daylight saving rules.
- If the hour cannot be confirmed, generate adjacent-hour charts and compare them with past life events.
Is the chart result accurate?
There are two layers. The calculation itself follows fixed rules, so if the birth data is correct, the chart output should be consistent across systems. The interpretation is where skill matters. Accuracy depends on whether the reader understands stars, palaces, brightness, Four Transformations, and timing layers.
