Saju Match — Korean Compatibility, Explained

What it does

Give it two birthdates. It returns a compatibility score and the traditional reasoning behind it.

Why it's different

Most compatibility readers give you a number and some warm sentences. There is no way to check where the number came from — usually because it came from nowhere.

This one derives the score from four named relations in Korean saju:

• Day-stem five elements — 相生 (generating) / 比和 (same) / 相剋 (restraining)
• Yin-yang balance between the two day stems
• Year branch (zodiac animal) — 三合 / 六合 / 沖 / 元嗔 / 害
• Day branch (spouse palace) — the seat traditional saju reads for life at close range

Every point traces to a relation you can look up.

Sample output

Compatibility: 92 / 100 — "Two people who make each other better"

Why
  - 甲木(yang) × 丁火(yin) → 木生火, generating (+12), yin-yang balanced (+4)
  - Tiger 寅 × Rabbit 卯 → no named relation (0)
  - 子 × 丑 → 六合, six-harmony (+10)
  (66 + 12 + 4 + 0 + 10 = 92)

Notes

• Needs only birthdates — no birth time required.
• Day pillars are computed from the Julian day number, verified against published 만세력 sources.
• Births in early February are flagged, since the zodiac year turns at 입춘 rather than January 1.
• Answers in English by default, Korean on request.

Traditional interpretation, for entertainment.
