What you need before you start
Zi Wei Dou Shu needs a Gregorian birth date, a traditional time period, and a sex option. The page shows chart details without judging personality or predicting events.
Birth date (solar)
date required
Builds the lunar conversion and basic twelve-palace structure.
Example: 1990-06-15
What to enter: Must be a valid Gregorian date no later than today.
If you leave it out: The chart cannot be generated.
Birth time
choose required
Determines time-dependent palace and star placements.
Example: Early Zi (00:00-01:00)
What to enter: Select one traditional time branch.
If you leave it out: A complete chart cannot be generated.
Traditional chart-direction rule
choose required
Sets the traditional chart-direction rule.
Example: Female-rule option
What to enter: Select one option; this is not a finding about gender identity.
If you leave it out: The chart cannot be generated.
How it works
This tool uses the details you enter on the page to produce a result. It is free to use, and your information is not sent to a third-party AI service.
Complete example
Worked example: one complete twelve-palace structure
This fictional example uses a birth date, time branch, and one of the two traditional chart-direction rules. That choice is only for charting and is not a statement about the user’s gender identity.
Example details
- Gregorian birth date
- 1990-06-15
- Traditional time branch
- Wu · 11:00-13:00
- Traditional chart-direction rule
- Female-rule option
Example result
- Converted record
- 一九九〇年五月廿三 · 午时
- Life palace
- 戊子 · 武曲 (旺, 化权) · 天府 (庙)
- These are traditional chart details, not a personality description.
- Body-palace marker
- 命宫
- Five-elements class
- 火六局
- Displayed so the chart can be checked again, not as evidence of a real-world outcome.
How to check it again
Generate the chart again with the same date, Wu time, and chart-direction rule. Confirm all twelve palaces; do not verify the chart by choosing whichever star description feels accurate.
What this example cannot prove
The page does not correct birthplace, historical time zone, daylight saving, longitude, or true solar time. Palaces, stars, transformations, and decade fields cannot establish personality or predict events.
Use cases
Recommended
Verify the twelve-palace chart
Inspect palace stems and branches, body palace, stars, related markers, and transformations.
Recommended
Compare possible birth branches
Generate every plausible candidate chart and retain only details that remain stable across the uncertain range.
Infer personality or future events
Palaces, stars, transformations, and decade ranges cannot prove personality, health, wealth, relationships, or event outcomes.
What the result is based on
Traditional Zi Wei charting
Builds the twelve-palace chart from a Gregorian date, time branch, and one of two traditional chart-direction rules.
Twelve-palace details
Records palace names, stems, branches, body-palace state, and related traditional cycles.
Stars and transformations
Lists stars, brightness, Lu, Quan, Ke, and Ji without generating a personality conclusion.
Decade and age ranges
Keeps the age ranges so the chart can be checked again without turning them into decade or annual forecasts.
What you will see
Birth details and conversion
Shows the date, time branch, traditional chart-direction rule, and lunar conversion.
Complete palace grid
Displays stems, branches, stars, and body-palace markers in all twelve palaces.
Star and transformation detail
Lists all stars, brightness, and transformations palace by palace.
Uncertainty record
Explains unapplied location and time-zone corrections and which details change between candidate birth branches.
What you can do next
Save the chart details
Keep date, time range, birthplace, time zone, and traditional chart-direction rule with the chart.
Compare candidate charts
Mark every palace, star, transformation, and decade range that changes across plausible times.
Stop outcome inference
Return real decisions to domain evidence instead of using a chart in place of consent, diagnosis, contracts, or qualified advice.
Time and chart-direction rule
Both can change the chart and need to be selected clearly.
Location and time zone
The page does not collect birthplace or correct historical time zone, daylight saving, longitude, or true solar time.
No outcome inference
Star keywords cannot establish personality, reverse-engineer birth time, diagnose health, measure income, rate a relationship, or predict events.
What this page calculates
A Gregorian date, birth-time branch, and required two-option traditional chart-direction rule produce the twelve palaces, palace stems and branches, body-palace marker, stars, transformations, and decade ranges.
These are traditional chart details. The page does not convert them into personality, ability, health, wealth, relationship, or future-event conclusions.
What each input changes
The date supplies the calendar conversion. The birth-time branch changes time-dependent palace and star placement. The two-option traditional rule sets chart direction; it is not a finding or statement about the user’s gender identity.
The page does not collect birthplace, historical time zone, daylight-saving status, longitude, or true solar time. A boundary case therefore requires multiple candidate charts rather than a confident hidden default.
How to verify the palace grid
Check the central birth record before inspecting each palace. Keep the chosen chart method and every detail that changes between plausible times.
- Keep the date, uncertain time range, birthplace, historical time zone, and traditional chart-direction rule.
- Compare each palace name, stem, branch, body-palace marker, and complete star list.
- Mark every star, transformation, decade range, and age that changes across candidate times.
- Retain only stable chart details and do not select the chart with the most flattering wording.
What star details cannot prove
Palace names, star names, brightness, transformations, decade ranges, and ages belong to a traditional classification system. They cannot establish personality, skill, psychological state, diagnosis, income, career performance, relationship quality, or whether an event will occur.
This page therefore displays chart details without generating personality summaries or annual predictions.
Privacy and stop conditions
Your birth date, time branch, and chart-direction choice are used only for the current chart. They are not saved after you refresh or close the page and are not sent to a third-party AI service.
Stop using the chart whenever a medical, investment, employment, legal, consent, relationship-safety, or emergency decision depends on one of its details. Use records, direct communication, and qualified advice from the relevant domain instead.
Why does birth time matter for a Zi Wei chart?
The birth-time branch changes palace and star placement. If the time is unknown or crosses a boundary, generate every candidate chart and mark differences; never infer a precise time from a personality description.
Can one palace or star predict a specific event?
No. This page does not turn a palace, star, transformation, decade range, or age into an event prediction or probability.
Why does the form ask for a male-rule or female-rule option?
Traditional Zi Wei Dou Shu uses this choice for parts of chart direction. It is used only for charting and is not a statement about gender identity, personality, or social role.
What happens if my birth time is approximate?
Palace and star placement can change across a time boundary. Test the plausible time ranges, keep both charts when needed, and avoid precise conclusions that depend on one uncertain palace. Do not infer a private birth time from personality descriptions.
How should I compare charts across a possible birth-time boundary?
Generate every plausible chart using the same calendar, time-zone, and conversion method. Mark which palaces, major stars, transformations, or decade ranges change, then restrict interpretation to features that remain stable. Keep the uncertainty beside every time-dependent statement. Save all candidate charts and the unresolved time range instead of overwriting them with a preferred result. Do not choose the chart that sounds more flattering and do not infer a private birth time from personality language. If an important decision depends on one changing palace, the chart is too uncertain to support that use.
