Bazi compatibility tool. Two charts → year-zodiac compat + day-master compat + 五行 complementarity + overall rating. More detailed than zodiac-only matching.
Bazi Compatibility Match (八字合婚)
How to use
Enter both birth profiles
Gregorian date + hour for both people. The tool converts internally to lunar bazi for comparison.
Review 3 dimensions
Year-zodiac compat (year pillar), Day-master compat (day pillar), 五行 complementarity — the three core 八字合婚 axes.
Read overall rating
Excellent / Good / Neutral / Caution / Weak — aggregated from the three dimensions. Algorithmic only — not a decisive verdict.
Read the interpretation
Each dimension has detailed relationship insight. Combine with practical considerations (personality, values, shared goals) for final judgement.
Bazi Compatibility Match: 1000-year Chinese Matchmaking
Bazi compatibility (八字合婚) is the core tradition of Chinese marriage matching. Compared to simple zodiac-only matching, it uses all 8 characters of both people\'s charts for a more nuanced compatibility analysis. From year pillar through hour pillar, from day-master to Five Elements, bazi compatibility covers multiple independent dimensions — avoiding the over-simplification of zodiac-only checks.
Three core dimensions
(1) Year-pillar match — same as zodiac compatibility, assessing "family-line" alignment (六合/三合/相冲/相害). (2) Day-pillar match — day-master element relationship, assessing "husband-wife" baseline interaction (generation, same-element, conquest). (3) 5-element complementarity — do the two charts together cover all 5 elements with balance?
Historical heritage
Bazi matchmaking originated in the Tang-Song, was consolidated in the Qing 《通书》. HK + Taiwan + ASEAN Chinese marriage tradition retains it — many older generation elders still consult 命理师 for compatibility before marriage. This tool provides introductory algorithmic output for family conversation + self-reflection.
"Marriage starts with bazi — but lasting relationships depend on both partners\' effort and growth."
Disclaimer
This tool computes per public algorithms and does not constitute marriage, relationship, or partner-selection advice. Algorithmic ratings are cultural frameworks, not scientific predictions. Any relationship decision should rest on practical compatibility, shared values, and mutual commitment. Use this for cultural reference + family conversation, not as a substitute for professional consultation. Overseas Chinese (US/UK/AU/CA/SG/MY/ID/PH) can use it for traditional-knowledge preservation.
10 Facts about Bazi Compatibility
Bazi compatibility theory formed in the Tang and was consolidated in the Qing — China's longest-continuous matchmaking tradition.
More nuanced than zodiac-only — 8 characters give multi-dimensional information that 1 zodiac cannot, avoiding over-simplification.
HK 2024 wedding-services survey: ~30% of couples consulted a 命理师 for bazi compatibility before marriage — the tradition remains living.
Generation between day-masters (e.g. metal-water) is considered best — one supports/nurtures the other. The ideal state in compatibility theory.
Element complementarity is a "hidden" dimension — few 命理师 explicitly mention it, but this tool surfaces it as a relatively objective compat axis.
This tool covers 3 dimensions; full professional matchmaking also checks annual flux (流年), 10-year cycles (大运), date selection (择日). Gap: introductory vs deep-dive.
A 2020 academic study (Sociological Review) of 5,000 mainland-China couples found no statistical correlation between bazi compatibility score and marriage stability.
Bazi compatibility isn't only for marriage — also business partnerships, teacher-student relationships, family-harmony analysis. The tool works for those use cases too.
Traditional matchmaker fees range HK$200-2000 (2024 HK data) depending on depth + practitioner reputation. This tool offers introductory analysis free.
This tool is suited for cultural entertainment + family conversation, NOT as decisive evidence for marriage choice. Always combine with practical considerations.
Frequently Asked Questions
-
Absolutely no. Don't reject a relationship based on bazi alone. Bazi compatibility is a cultural framework lacking scientific validation. Relationship stability depends on mutual effort, shared values, and commitment.
-
Zodiac compat (RT-CHN-007) checks year pillar only (2 chars). This tool checks all 8 + 五行 complementarity — more comprehensive. When they disagree, defer to the bazi version.
-
Aggregated from 3 dimensions: year-zodiac (highest weight, 六合 best), day-master interaction (mid, generation best), 五行 complementarity (base, all-5 best). Excellent = all 3 good; Weak = multiple negative or 相冲.
-
No. Browser-local, no server calls.
-
Use 12:00 as approximation. Year/month/day pillars stay accurate; only hour pillar is affected. Full matchmaking is best with exact times, but approximations still give meaningful comparison.
-
Yes — as a cultural-reflection + self-understanding tool. But do not use it to second-guess a marriage decision. Algorithmic results are cultural frameworks; they should not override the relationship you've built.
-
Absolutely not. HK + SG/MY/ID see plenty of clash-zodiac couples in happy marriages. Tradition offers remedies — auspicious wedding dates, home-orientation adjustment, etc. What matters most is genuine mutual care.
-
Defer to the practitioner. They integrate annual flux, 10-year cycles, date selection — many more dimensions than this introductory 3-axis tool. Disagreement isn't error; it's depth difference.
-
Yes — bazi itself is gender-neutral. Compatibility analysis applies between any two people. Zodiac, day-master, and 五行 complementarity concepts don't depend on partner gender.
-
Yes — business partnerships, teacher-student, parent-child relationships all work. The "compatibility analysis" framework isn't limited to marriage.
