Korean Four Pillars, explained properly.

Start with the two things a chart is built from: the ten day masters (the stem that anchors your reading) and the five elements they balance. Then the articles below go deeper. In a hurry? The quick answers page covers the most-asked saju questions in a paragraph each.

• When Does the Saju Year Actually Start? Not Lunar New Year — Ipchun

  The single most common saju mistake: assuming the year changes at lunar new year. It doesn't. The year pillar turns at Ipchun in early February, on the sun's position — and that fixes January babies' charts.

• Gaemyeong: Why Koreans Legally Change Their Names After a Saju Reading

  In Korea, changing your legal name after a fortune reading is a real, common, court-approved thing. Here is what gaemyeong is, how names connect to a saju chart, and why the practice sits at the edge of what saju actually claims.

• Why Do Saju Calculators Disagree, and How to Tell Which Reading Is Right

  Two saju sites can hand you two different charts from the same birthday. Here is exactly why it happens — the solar-term boundary, the late-night hour, the time zone — and how to check which chart is correct.
