Saju vs BaZi
Saju (四柱, 사주) and BaZi (八字) are two names for essentially the same system: the Four Pillars of Destiny, a chart of eight characters drawn from the year, month, day and hour of your birth. The underlying calendar math — Heavenly Stems, Earthly Branches, the Five Elements — is the same. What differs is mostly the name (Saju is Korean, BaZi is Chinese), the interpretation tradition, and small regional conventions.

| The chart | Same: 4 pillars · 8 characters · Five Elements | Same: 4 pillars · 8 characters · Five Elements |
| Tradition | Korean schools (e.g. 자평·궁통보감 lineage) | Chinese schools (e.g. Zi Ping, Blind reading) |
| Flavor | Often more relational / counseling-leaning | Often more structural / luck-cycle-leaning |
Is Saju the same as BaZi?
At the chart level, yes — both are the Four Pillars of Destiny built from the same birth-date math (Heavenly Stems, Earthly Branches, Five Elements, Ten Gods). 'Saju' is the Korean name, 'BaZi' the Chinese one — same chart underneath. The differences are in interpretation tradition, emphasis and small regional conventions, not in the chart itself.
If they're the same, which should I use?
The chart is identical, so choose by which interpretation tradition resonates. Korean Saju often reads more relationally (how you relate, your inner weather); Chinese BaZi often emphasizes structure and ten-year luck cycles. Gwiraedang uses Korean Saju, computed by its own deterministic engine and discussed by five AI counselors in your language.
Will my Saju and BaZi charts differ?
They shouldn't — if computed correctly they're the same eight characters. Any difference almost always traces back to a calculation error — a wrong solar term, true solar time, or daylight saving offset — the same mistakes general AI chatbots make. Gwiraedang computes deterministically and verifies against KASI to ±1–2 minutes.
