What is compared
- Day Masters: the element and polarity relationship between the two people.
- Day branches: traditionally linked to close partnerships.
- Element balance: whether one chart supplies what the other lacks, or both are heavy in the same place.
- Branch combinations and clashes: harmony and friction between the charts.
- Timing: how each person's current Luck Pillar shapes the relationship now.
Stem combinations
Five pairs of Heavenly Stems combine in traditional theory: 甲己, 乙庚, 丙辛, 丁壬, and 戊癸. When two Day Masters form one of these pairs, readers often describe a natural pull between the two people.
How this differs from zodiac matching
Zodiac matching compares only year animals, which is one branch out of eight characters per person. Full BaZi compatibility looks at the whole chart, so two people with “incompatible” zodiac animals can still have strong support in their full charts.
Why a score is only a starting point
A compatibility score compresses a lot into one number. It is more useful to ask where you support each other and where friction tends to appear. No chart can tell you whether a relationship should continue.
Daoly's Match feature on iPhone compares two charts and explains communication, growth, and friction patterns rather than offering a verdict.
