What This BaZi Compatibility Calculator Checks
A useful BaZi compatibility calculator should compare more than Chinese zodiac animals. TryBazi starts with both birth dates, builds a simplified Four Pillars profile, and reads the relationship through the Five Element cycle. The free result gives a fast compatibility score, while the supporting guides explain the deeper Day Master and Spouse Palace logic.
Day Master compatibility
The Day Master is the core self in BaZi. The calculator checks whether the two dominant elements generate, control, mirror, or operate independently from each other.
Five Element balance
Each chart is summarized through Wood, Fire, Earth, Metal, and Water. Complementary charts can fill each other's missing elements; overloaded charts can amplify the same blind spots.
Spouse Palace context
The Day Branch, often called the Spouse Palace, is central for marriage and dating compatibility. The calculator introduces the pattern; the guide pages explain combinations and clashes in more detail.
Relationship use case
You can use the same BaZi compatibility test for romantic partners, marriage timing questions, close friendships, or business partnership dynamics.
For the full interpretive framework, read the BaZi compatibility guide after you run the calculator.

What Is BaZi Compatibility?
BaZi compatibility compares two people's Four Pillars charts to understand how their elemental energies interact. Unlike Western sun-sign compatibility, BaZi examines the complete chart — all eight characters across four pillars — to identify where two people naturally support each other, where they create productive tension, and what each person must understand to make the relationship thrive.
The most important pillar for romantic compatibility is the Day Pillar — specifically the Day Branch, called the Spouse Palace. When two people's Day Branches combine (六合), there is a natural pull. When they clash (六冲), there is intensity, transformation, and growth through friction.
How to Read Your Compatibility Results
One person's dominant element produces the other's — natural support, complementary energy. The relationship often feels easy from the start, though dependency can form over time.
Both charts share the same dominant element — deep mutual understanding and shared blind spots. The relationship amplifies both strengths and weaknesses simultaneously.
One element controls the other in the Five Element cycle — creating productive friction. These relationships drive growth and transformation but require conscious navigation to avoid power struggles.
Elements operate in parallel without strong generating or controlling interaction. The relationship grows through deliberate effort and shared goals rather than intrinsic elemental pull.
The 5 Factors That Determine BaZi Compatibility
1. Day Branch Interaction
The Spouse Palace (Day Branch) combination or clash is the single most important compatibility indicator. Combinations create natural ease; clashes create intensity and transformation.
2. Day Master Elemental Relationship
How the two core selves (Day Masters) relate in the Five Element cycle — whether one generates, controls, or resonates with the other — shapes the fundamental dynamic of the relationship.
3. Five Element Balance
Charts that complement each other's elemental deficiencies create a sense of completion. Two charts heavy in the same element understand each other but may compound shared weaknesses.
4. Spouse Star Expression
Each Day Master has a specific elemental energy it is wired to attract. A chart that carries its own Spouse Star strongly will draw that energy powerfully — in its healthy or shadow form.
5. Luck Pillar Timing
The same chart combination can feel harmonious or strained depending on what decade each person is in. A challenging pairing during mutually supportive luck cycles is very different from the same pairing during conflicting ones.

BaZi Compatibility Calculator vs Chinese Zodiac Compatibility
Many people search for a Chinese compatibility calculator and only get birth-year animal matching. BaZi is more specific because it compares the full chart structure, especially the Day Pillar.
Uses the birth-year animal. Fast, simple, but too broad for serious relationship analysis.
Uses birth date, Day Master, Day Branch, and Five Element balance to compare the actual chart dynamics between two people.
Adds both full Four Pillars charts, Spouse Star analysis, clashes/combinations, and Luck Pillar timing.
Specific BaZi Compatibility Pairings
After you run the calculator, use these focused compatibility breakdowns to compare specific Day Masters and Day Pillars. Each guide targets a different long-tail BaZi relationship query so the site no longer depends on one broad article for the entire compatibility topic.
Frequently Asked Questions
How does the BaZi compatibility calculator work?
The calculator converts each person's birth date into a Five Element profile from their Four Pillars chart, then compares the dominant elements to determine whether they generate, control, or resonate with each other — producing a compatibility score and dynamic description.
Can I check BaZi compatibility by birth date only?
Yes. You can run a quick BaZi compatibility check with two birth dates. Birth times improve the Hour Pillar, but the birth date is enough to estimate each person's Day Master, Day Branch, Five Element balance, and relationship dynamic.
Do I need birth times for BaZi compatibility?
Birth times improve accuracy by completing the Hour Pillar, but the analysis runs without them. The most important pillars for compatibility are the Day Pillars, which only need birth date.
What does a high compatibility score mean?
A higher score indicates naturally supporting or resonating elemental profiles. But no score predicts whether a relationship will succeed — it describes the energetic quality of the interaction. Many great relationships carry "difficult" chart dynamics.
Can I use this for business partnership compatibility?
Yes. BaZi compatibility applies to any close relationship. For business, the focus shifts to whether the two Day Masters are in a productive or controlling relationship, and whether both charts activate wealth stars together.
What is a BaZi Day Branch clash?
A Day Branch clash occurs when two people's Spouse Palaces (Day Branches) are in direct opposition — for example, Rat and Horse, or Rabbit and Rooster. Clashes produce intensity and transformation, not failure. Many lasting relationships carry a Day Branch clash.
Is this the same as Chinese zodiac compatibility?
No. Chinese zodiac compatibility usually compares only the birth-year animal. BaZi compatibility uses the full Four Pillars chart, especially the Day Master, Day Branch, Five Element balance, and timing cycles.
What makes TryBazi different from a simple Chinese zodiac match?
TryBazi compares the relationship through BaZi logic instead of only birth-year animals. The free calculator reads Five Element balance, dominant element interaction, Day Master context, and Spouse Palace concepts, then links to deeper Day Master and Day Pillar guides.
Can two clashing BaZi charts still work?
Yes. A clash describes pressure, movement, and transformation. It does not mean the relationship should end. The useful question is where the clash appears and whether both people can work consciously with the pattern.
