In Korean culture, checking Saju compatibility (궁합, gunghap) before marriage is a tradition that dates back centuries. Even in modern Korea, many couples visit a Saju master to evaluate their cosmic compatibility before committing to marriage. While some view it as superstition, many Koreans consider it a form of wisdom — a way to understand potential relationship dynamics before they unfold.

Saju compatibility analysis examines how two people's birth charts interact across multiple dimensions. The most fundamental assessment looks at the Five Element relationship between the two Day Masters. The generating cycle (상생, sangsaeng) — where one element naturally supports another — is considered the most harmonious: Wood feeds Fire, Fire creates Earth, Earth produces Metal, Metal generates Water, and Water nourishes Wood.

The controlling cycle (상극, sangguk) isn't necessarily negative in compatibility readings. Some degree of creative tension keeps a relationship dynamic and growing. However, when one partner's Day Master strongly controls the other's without reciprocal support, the relationship may feel imbalanced — one person constantly dominant and the other constantly yielding.

Beyond the Day Master comparison, Saju masters examine the Earthly Branches across both charts for special combinations. "Three Harmonies" (삼합, samhap) occur when certain Branch combinations create powerful elemental harmony. For example, if one person's chart contains the Horse branch and the other's contains the Tiger and Dog branches, they complete a Fire triangle — indicating passionate, energizing compatibility.

Certain Branch combinations are considered particularly challenging. The "Six Clashes" (육충, yukchung) occur when opposing Branches appear across two charts, potentially creating friction and misunderstanding. For example, Rat and Horse are opposing Branches — if prominently placed in both charts, communication challenges may arise. However, experienced Saju masters emphasize that clashes can also create exciting, dynamic energy when other chart factors are supportive.

Modern Korean Saju practitioners take a holistic approach to compatibility. Rather than declaring a match "good" or "bad," they identify the specific strengths and potential friction points of the pairing. They might advise: "Your Water energy will naturally support their Wood energy, creating a nurturing dynamic in the relationship. However, be mindful during Earth-heavy months when both of you may feel restricted."

One traditional compatibility idea is complementary balance: readers may compare an element that is less visible in one chart with an element that is more prominent in the other. This is a metaphor for discussing different strengths, not evidence that two people are naturally destined to attract or complete each other.

Saju compatibility cannot determine whether a relationship will be healthy or successful. Consent, safety, communication, respect, patience, and repeated behavior are the evidence that matters. Use a chart comparison only to generate neutral questions that both people are comfortable discussing.
