Chinese zodiac personalities, match table and how compatibility is read →
Compatibility readings are a traditional reference describing tendencies, not a verdict on whether two people belong together. Relationships depend on communication, respect and effort; do not base a decision about marriage on this result.
How to use it, and common questions
How to use it
- Enter both people's Gregorian birth dates and times. If a birth time is unknown, tick "Birth time unknown"; the year, month and day pillars can still be compared.
- Press the button to cast both sets of four pillars and compare four aspects: zodiac signs (year branches), the spouse palace (day branches), the relation between the day stems, and whether each person's favourable elements are supplied by the other's chart.
- The overall summary lists the strengths of the match and the areas that need care.
What the four aspects mean
- Zodiac signs: six-harmony and three-harmony pairs of year branches are more harmonious; clash, harm and punishment pairs call for more adjustment.
- Spouse palace: the day branch is traditionally the spouse palace; the relation between the two day branches reflects how the couple relate in close quarters.
- Day stems: the day stem stands for the person. A combination suggests mutual attraction; one producing the other suggests one gives more; one controlling the other suggests one leads more strongly; the same element suggests an equal, friend-like bond.
- Complementary elements: from each day master's strength, find the elements each person needs, then see how much of them the other's chart contains.
Common questions
- Does a poor result mean we should not be together?
- No. Compatibility describes tendencies in how two people relate and points to where more communication helps. It is not a verdict on whether a relationship can work; that depends on communication, respect and effort from both sides.
- Can same-sex couples or friends use it?
- Yes. The comparison uses zodiac signs, day branches, day stems and elements, does not change with sex, and applies to any two people.
