What this tool is useful for
Compare two birth profiles with the traditional rules explained on this page, then organize questions about communication, expectations, recurring friction, boundaries, and practical relationship work.

BaZi
Compare two anonymous birth profiles with the traditional rules explained on this page, then turn the result into questions about communication, expectations, boundaries, and uncertainty rather than predicting relationship outcomes.
Output preview
The output below shows what this tool can document. Input details and examples are explained in the next section.
2 input details explained below
Traditional comparison record
Shows the reference score and chart features used, without presenting the number as a relationship probability.
Anonymous chart records
Shows Profile A and Profile B charts and any input uncertainty without collecting names or gender.
Reality-check questions
Lists communication, boundaries, safety, money, and family responsibilities that require direct evidence.
This worksheet compares two anonymous birth profiles. Dates are required and times remain optional; it does not collect names or relationship status. Enter the second person's data only with permission.
Person A birth date
date required
Establishes the calendar and timing data used by the calculation.
Example: 1990-06-15
What to enter: Use a valid calendar date that is not in the future.
If you leave it out: The tool cannot produce a reliable result without this required value.
Person B birth date
date required
Establishes the calendar and timing data used by the calculation.
Example: 1990-06-15
What to enter: Use a valid calendar date that is not in the future.
If you leave it out: The tool cannot produce a reliable result without this required value.
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
These fictional records demonstrate one complete calculation path. Exact local clock times are supplied so the example includes both hour pillars; the page still cannot correct birthplace, time zone, daylight saving, or true solar time.
Re-enter both records and compare the two charts and four topic scores. If any value differs, first check the times and calendar method; do not average two results or keep only the preferred score.
This example demonstrates the formula only. It does not show that the two profiles are compatible, should marry, should separate, or will experience a particular outcome.
How to use it
Compare two birth profiles with the traditional rules explained on this page, then organize questions about communication, expectations, recurring friction, boundaries, and practical relationship work.
Turn the traditional-rule reference score into questions about communication, expectations, boundaries, safety, and cooperation.
Turn report themes into questions about expectations, boundaries, money, family, and long-term plans.
A chart cannot reveal another person’s intent and cannot replace direct communication, counseling, or legal advice.
Compares Day Master elements, traditional year-stem and branch relations, visible element-count differences, and month branches; it does not judge Ten Gods roles or relationship quality.
Explains how the overall and topic scores are adjusted and rounded; the numbers are not relationship probabilities.
Turns cultural labels into questions both people must discuss and verify instead of claiming to measure emotion or relationship quality.
Shows the reference score and chart features used, without presenting the number as a relationship probability.
Shows Profile A and Profile B charts and any input uncertainty without collecting names or gender.
Lists communication, boundaries, safety, money, and family responsibilities that require direct evidence.
Turns the reading into observable actions and questions for both people.
Choose two or three themes to discuss rather than treating the traditional-rule reference score as a verdict.
Return after a month and record whether communication or expectations became clearer.
Do not use the report to declare that a couple must marry, separate, reconcile, or tolerate unsafe behavior.
Enter another person’s birth details only with permission. Details are used only for the current result and are not saved after the page is refreshed or closed.
The reference score comes from the fixed traditional relations listed on this page. It is not trained on relationship outcomes, has not been tested against real relationship data, and must not be read as a probability of compatibility, marriage, separation, or safety.
The calculation begins at 70, applies only the Day Master and year-pillar relations below, and displays a result from 50 to 95. Names, gender, relationship stage, income, appearance, and private behavior do not change the score.
| Traditional relation | Score change | What is actually compared |
|---|---|---|
| Same Day Master element | +8 | The element assigned to each day stem is the same |
| Day Master elements generate one another | +15 | Either element precedes the other in the traditional generating cycle |
| Day Master elements control one another | -12 | Either element precedes the other in the traditional controlling cycle |
| Year stem combination or year branch Six Harmony | +6 | The year-pillar pair appears in a fixed traditional lookup set |
| Year branch clash | -8 | The year branches appear in the fixed Six Clashes lookup set |
These four values summarize only the traditional relations listed here. They do not measure communication, collaboration, money behavior, caregiving, fertility, or relationship quality. Every value remains within the stated range after the listed additions and deductions.
The labels organize discussion only. Real behavior, consent, safety, values, responsibilities, financial records, and conflict repair take priority over every reference score.
| Discussion topic | Starting value and rules | Display range |
|---|---|---|
| Interaction | Start 60; +25 generating Day Masters; +15 same element; -10 controlling relation; +10 year harmony | 40-100 |
| Collaboration | Start 65; +15 without year clash; +12 year harmony; +8 generating or same Day Masters | 45-100 |
| Resources | Start 60; +20 when both element spreads are at most 2, otherwise +10 when either spread is at most 3; +10 generating Day Masters | 45-100 |
| Caregiving | Start 65; +15 month-branch harmony; +10 without a month-branch clash | 45-100 |
The calculation uses the two visible Day Master elements, selected year-stem and year-branch lookup pairs, visible element-count spreads, and the two month branches. It does not calculate Ten Gods relationship roles, spouse palaces, attachment style, intent, consent, safety, fertility, or future timing.
When either birth time is unknown, the hour pillar is omitted. The page keeps that uncertainty visible, but even complete birth details cannot turn a traditional chart comparison into a measurement of relationship quality.
Use the four labels only to organize a conversation, then answer them without relying on the chart.
Select one discussion question and one observable agreement. Record the starting problem, both people's wording, the action, consent, review date, supporting evidence, and counterevidence. Do not ask one partner to accept a chart label as a fact about them.
After 30 days, mark the agreement keep, revise, or stop. A change in real communication does not prove the reference score accurate; it only shows whether the agreed action helped during that period.
Do not use a reference score to decide whether someone is trustworthy, whether to marry or separate, whether to have children, or whether unsafe behavior should be tolerated. Enter another person's birth details only with permission.
Relationship safety, legal rights, housing, immigration, money, mental health, and medical decisions require direct evidence and qualified support from the relevant domain. A second chart calculation cannot resolve those issues.
The report documents the two calculated profiles, compares a declared set of five-element and branch relationships, and turns the result into discussion prompts about communication, expectations, boundaries, and uncertainty.
Yes. Birth time improves detail, but you can leave it unknown and still generate a preview.
Treat the score as a prompt, not a verdict. Verify the birth inputs, read the separate communication and lifestyle factors, and discuss one real example together. A relationship cannot be accepted or rejected by a chart score, and concerns about safety or coercion require qualified support rather than another calculation.
