Birth details

No name, gender, email or account needed.

Birth date · Gregorian

How certain is the time?

Recorded local timeBirthplace · city, country

Use the time written on the birth record, not a conversion to Beijing time. We do not adjust for longitude or true solar time.

Birthplace time zone

Type a city or region to find an IANA zone. This is not an automatic birthplace lookup. Use the zone for the birthplace—not your current location. Historical local rules may need checking.

I have checked that this time zone applies to the birthplace.I understand this is a symbolic chart, not a prediction. Birth details are processed in this browser and are not sent to or saved by the calculator. Only if I separately choose to keep a report will the four derived pillar pairs be saved to my account.

The arrangement below is a teaching illustration, not a chart calculated from anyone’s birth details. Your calculated chart appears separately above. You can choose to keep its derived pillar pairs in your private account journal.

四柱Four Pillars

One framework, four viewpoints.

Illustration only

The day pillar

A reference point

The day’s heavenly stem is often called the Day Master. It is a reference within the traditional model, not a scientifically established personality type.

Click a pillar to explore its role. These four pairs illustrate the display only; they are not claimed to form a valid, calculated birth chart.

Grounded curiosity. Honest limits.

五行Five phases

Five phases, not five boxes.

Wood, Fire, Earth, Metal, and Water describe traditional relationships and processes. They are not literal substances that determine who you are.

時

Time needs care.

Time zones, solar terms, calendar boundaries, and school-specific conventions can affect a chart. We will show our method rather than hide these choices.

人

You are more than a chart.

Your choices, relationships, and circumstances are not reducible to symbols. We frame this tradition as cultural study and reflection, not established science.

Your free reading and optional deeper report use selected passages from the local San Ming Tong Hui research database, alongside clearly labelled modern reflection prompts. Source notes show the scan pages and translation-review limits. These are cultural and reflective interpretations, not predictive reports.
