What you need before you start

Zi Wei Dou Shu requires a Gregorian birth date, a selected traditional time period, and the traditional sex parameter used by the iztro chart rule. The page shows structural fields and does not infer personality or events.

Birth date (solar)

required

date required

Builds the lunar conversion and basic twelve-palace structure.

Example: 1990-06-15

Validation: Must be a valid Gregorian date no later than today.

If missing: The chart cannot be generated.

Birth time

required

choose required

Determines time-dependent palace and star placements.

Example: Early Zi (00:00-01:00)

Validation: The user must select one iztro time index from 0 through 12.

If missing: A reviewable chart cannot be generated.

Traditional chart parameter

required

choose required

Acts as iztro’s required two-option traditional chart-direction parameter.

Example: Female-rule option

Validation: Must be selected explicitly and is not a finding about gender identity.

If missing: The library cannot generate the chart.

How it works

This live tool calculates the result directly from the information shown on the page. You can use it right away without payment, and the form is not sent to an AI model.

Reproducible worked example

Worked example: one complete twelve-palace structure

This fictional input demonstrates the exact parameters passed to iztro. The two-option chart parameter is an engine switch used by the traditional rule; it is not a statement about the user’s gender identity.

How to verify it

Regenerate the chart with date, time index 6, the same traditional parameter, and the current iztro version. 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 structure

Inspect palace stems and branches, body palace, stars, auxiliary fields, and transformations returned by the library.

Recommended

Compare possible birth branches

Generate every plausible candidate chart and retain only fields that remain stable across the uncertain range.

Not recommended

Infer personality or future events

Palaces, stars, transformations, and decade fields cannot prove personality, health, wealth, relationships, or event outcomes.

Method basis

iztro chart engine

Builds the twelve-palace structure from Gregorian date, time index, and a required two-option traditional chart parameter.

Twelve-palace fields

Records palace names, stems, branches, body-palace state, and auxiliary cycles returned by the library.

Star and transformation fields

Lists stars, brightness, Lu, Quan, Ke, and Ji without generating a personality conclusion.

Decade and age fields

Preserves returned ranges for reproducibility without turning them into decade or annual forecasts.

Report structure

Input and calculation record

Shows date, time index, traditional chart parameter, lunar conversion, and iztro output.

Complete palace grid

Displays stems, branches, stars, and body-palace markers in all twelve palaces.

Star and transformation detail

Lists all returned stars, brightness, and transformation fields palace by palace.

Uncertainty record

Discloses unapplied location and time-zone corrections and which fields change between candidate birth branches.

Actions and boundaries

Save the input policy

Keep date, time range, birthplace, time zone, and traditional chart parameter with the grid.

Compare candidate charts

Mark every palace, star, transformation, and decade field 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 parameter

Both can change the chart and must be selected explicitly rather than hidden behind defaults.

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

The tool runs the open-source iztro library in the browser. A Gregorian date, time index, and required two-option traditional chart parameter produce the twelve palaces, palace stems and branches, body-palace marker, stars, transformations, and decade fields.

These are reproducible traditional structure fields. 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 time index changes time-dependent palace and star placement. The two-option sex parameter is a switch required by iztro for traditional 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 center record before inspecting each palace. A useful verification record includes the input policy and every field that changes between plausible times.

  • Keep the date, uncertain time range, birthplace, historical time zone, chart parameter, and iztro version.
  • Compare palace index, name, stem, branch, body-palace marker, and complete star list.
  • Mark every star, transformation, decade, and age field that changes across candidate times.
  • Retain only stable structural fields and do not select the chart with the most flattering wording.

What star fields cannot prove

Palace names, star names, brightness, transformations, decades, and age fields belong to a traditional classification system and software output. They cannot establish personality, skill, psychological state, diagnosis, income, career performance, relationship quality, or whether an event will occur.

The reviewed page therefore displays raw structural fields and does not generate palace summaries or annual predictions.

Privacy and stop conditions

The reviewed tool calls iztro directly in the browser. Birth date, time index, and chart parameter are not sent to a site API, report database, AI provider, or analytics event. Refreshing the page does not restore the chart.

Stop using the chart whenever a medical, investment, employment, legal, consent, relationship-safety, or emergency decision depends on one of its fields. Use records, direct communication, and qualified advice from the relevant domain instead.

Why does birth time matter for a Zi Wei chart?

The time index 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. The reviewed page does not turn a palace, star, transformation, decade, or age field into an event prediction or probability.

Why does the form ask for a two-option chart parameter?

iztro requires a traditional male-rule or female-rule switch for parts of chart direction. The value is an explicit calculation parameter, 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 policy. 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, the software version, 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.
