- Four pillars contain four stem–branch pairs: eight characters.
Definition and details
The Academy of Korean Studies explains the four pillars through a house supported by four columns: birth year, month, day and hour. Each column pairs a stem and branch, giving eight characters. Learn Korean readings alongside the Chinese-character vocabulary and chart positions before moving from calendrical inputs to interpretive language.
Structure and history
Saju arranges birth information through calendrical symbols, unlike consultation by possession or a random cast. Shared stem-and-branch terminology does not make all Korean lineages identical to Chinese textbooks. Its history requires Korean publications and local evidence; a modern commercial website’s procedures cannot represent a whole population’s unchanged ancestral custom.
A concrete example
A teaching diagram can label a single year pillar Jiazi: Jia is the stem and Zi the branch. Add three columns for month, day and hour to show why the chart contains eight characters. This explains structure without reading anyone’s fate; actual calculation also requires explicit calendar and boundary conventions.
Context and limits
Interpretation adds assumptions about phase relations and individual outcomes to the chart’s calculable structure. An encyclopedia documents the tradition without proving personal forecasts. Compare terminology and consultation practice, but avoid judging ability, morality or marriage suitability from birth characters; reproducible symbolic calculation is not the same as reliable prediction.
References & further reading
Historical sources document ideas and rules of their time, not empirical proof of predictive accuracy. Source notes identify the nature and scope of each reference.
