Zodiac Compatibility (궁합)
Two birth dates give two animal signs and two day stems. Reports the exact relation between them — 삼합, 육합, 충, 원진, 형, 파, 해 — and the five-element relation of the day stems, each with the traditional verdict.
Two birth dates give two 띠 and two 일주, and the relations between them — 삼합, 육합, 충, 원진, 형, 파, 해 — are a fixed table that every 만세력 prints. The page reports which relations hold, quotes what the tradition says about each, and shows 겉궁합 and 속궁합 separately rather than merging them into a number. There is no percentage, and the page says why.
For fun. The 간지 of two birth dates and the relation between them are exact — that part is a calendar conversion and a fixed table. What the tradition says about each relation is quoted with its source. These were matchmaking heuristics, not measurements of people, and they tell you nothing about anyone.
Two birth dates
The 띠 turns at 입춘 here, which is the boundary a 만세력 uses — so a January birthday may give a different animal from the one you were told. The 띠·별자리 page shows all three boundaries side by side.
What was computed
| First person | Second person | |
|---|---|---|
| 띠 (year branch) | horse · 오(午) | monkey · 신(申) |
| 년주 | 경오 (庚午) · 1990 | 임신 (壬申) · 1992 |
| 일주 | 을해 (乙亥) | 계묘 (癸卯) |
| 일간 | 을(乙) · 목 | 계(癸) · 수 |
| Colour | 청색 | 흑색 |
| Numbers | 3 · 8 | 1 · 6 |
겉궁합 — the two 띠
The two branches are in none of the named relations. That is the ordinary case — eight of the twelve pairings for any given branch have no name at all — and the tradition has nothing in particular to say about it, which is itself worth knowing.
The coarsest reading in the system: the year branch divides everybody alive into twelve. It is what people mean by “궁합” in conversation, and it is worth remembering how blunt it is.
속궁합 — the two 일주
Traditionally the strongest of the harmonious relations. 『삼명통회』 describes the three branches four apart as pulling toward one element together, and 만세력 practice has always read a 삼합 pair as people who end up wanting the same thing without having to agree to.
The two day stems are in none of the named stem relations.
The second produces the first (상생). Traditionally read as being supported.
Finer, because the day pillar runs on a sixty-day cycle rather than a twelve-year one. This is what a 만세력 actually reads.
Why there is no percentage
Where the readings come from
- 『삼명통회(三命通會)』, 만민영, 1578 — the 합·충·형·해·파 tables as every 만세력 prints them.
- 『연해자평(淵海子平)』, 서승 편, Ming — 천간합 and the reading of 충.
- 『오행대의(五行大義)』, 소길, Sui (c. 600) — 상생 and 상극.
- 원진 as a 띠-pair table is Korean 만세력 practice and folk transmission; the classical term is older than the table people know.
The 간지 behind both dates is the same one the 사주팔자 page draws, and the day’s own 일진 is what the 오늘의 운세 page reads against your 띠.
How to use it
Enter two solar birth dates
The 띠 turns at 입춘 here, which is the boundary a 만세력 uses, so a January birthday may give a different animal from the one you were told. The 띠·별자리 page shows all three boundaries side by side if that matters.
Read 겉궁합 and 속궁합 as different questions
The 띠 against the 띠 is the coarsest thing in the system — it divides everybody alive into twelve. The 일주 against the 일주 runs on a sixty-day cycle and is what a 만세력 actually reads. They can and do disagree.
Read the whole list, not just the headline
A pair can hold more than one relation at once — 인해 is both 육합 and 파 — so the page names the harmony first but keeps the rest beside it. A tool that stopped at the first match would call a 파 a perfect fit.
Common questions
Why is there no compatibility percentage?
Because every one of those numbers is invented. There is no scale in 삼명통회, no arithmetic in the tradition that produces one, and “87% 궁합” is a made-up figure wearing the authority of a text that never issued it. The relations are named and the verdicts quoted; weighing them is what the matchmakers who used these tables actually did.
Are 원진 couples really bad matches?
These were matchmaking heuristics used to decide whether to proceed with a negotiation between two families who had not met — a way of settling a question quickly with the only information a matchmaker had, a pair of birth dates. They were never a measurement of two people. The 원진 table people know is also folk transmission rather than a chapter anyone can point at, which the page says.
What is 삼합?
Three branches four apart that pull toward one element together: 신·자·진 water, 해·묘·미 wood, 인·오·술 fire, 사·유·축 metal. It is the strongest of the harmonious relations in 『삼명통회』, and two of any such three are a 삼합 pair.
