How Saju Compatibility (Gunghap) Actually Works
Saju compatibility looks far beyond matching two zodiac signs. It reads how two complete charts interact — your Day Masters, the magnetic pull between your Heavenly Stems, your spouse palaces, and whether your five elements complete or clash with one another.
Day Master harmony
Each person’s core self (Day Master) relates to the other through the productive and controlling cycles of the five elements. One can nourish the other, or quietly wear them down — this is the foundation of any match.
Heavenly Stem Combinations (천간합)
Certain Heavenly Stems are drawn together in classical "combinations" — a magnetic pull that often shows up as instant chemistry or a sense of destiny between two people.
The Spouse Palace
The Earthly Branch beneath your Day Pillar describes what you instinctively seek in a partner. Comparing both people’s spouse palaces reveals how naturally you will understand each other.
Five-element balance
The strongest matches often fill each other’s gaps — one partner supplies the element the other lacks, creating a balance neither had alone.
Flow, not a pass/fail score
Real compatibility is never a single number. It is about where you naturally harmonize and where you will need to work — and knowing both is what makes a relationship last.
