Chinese BaZi
English-language material often presents the system through Chinese terminology such as Day Master, useful god, ten gods, and luck pillars. Schools differ, so two BaZi readers can still emphasize different parts of the same chart.
If you already know your BaZi chart, Korean Saju is not a different birth system. Both begin with the same eight characters: the heavenly stem and earthly branch for your year, month, day, and hour. The useful question is not “which one is correct?” but “what changes when the same chart is explained in a Korean tradition?”
Saju (사주, literally “four pillars”) and BaZi (八字, “eight characters”) share the core chart. Both examine the Day Master, five elements, ten gods, hidden stems, seasonal strength, combinations and clashes, and longer luck cycles. A correctly calculated chart should not change just because the interface uses a Korean or Chinese name.
The birth time still matters, and the month pillar follows solar-term boundaries rather than simply starting on the first day of a Gregorian month. If two tools produce different pillars, first compare their time-zone, daylight-saving, solar-term, and day-boundary assumptions before comparing interpretations.

Korean explanations use terms such as 일간, 오행, 십성, and 대운 and often connect them to familiar Korean cultural examples. The calculation is shared; the vocabulary, pedagogy, and emphasis can differ.
Neither label guarantees a better reading. A useful comparison shows its calculation assumptions, distinguishes chart facts from interpretation, and avoids treating symbolic patterns as medical, legal, financial, or deterministic advice.
The free Saju tool shows the Four Pillars, Day Master, five-element balance, ten gods, hidden stems, twelve life stages, void branches, major-luck cycles, and the current-year pillar. Use it beside the BaZi chart you already have and compare the calculated pillars first; then compare how the interpretation is framed.

1. Confirm that year, month, day, and hour pillars match. 2. Check how each tool handles time zone and solar terms. 3. Compare the Day Master and five-element distribution. 4. Note where the tools agree on chart structure but differ in interpretation. 5. Keep any prediction as a prompt for reflection, not a guaranteed outcome.
