Quick answer
Match two birth dates to see how their animals pair. The twelve animals form four trines: Rat, Dragon and Monkey share one, Ox, Snake and Rooster another, and the rest follow the same rule. A clash pair sits six places apart, and the table below gives every animal its best and worst match.
Chinese zodiac compatibility rates how well two of the twelve zodiac animals get along, using the traditional structured system of trines, clashes, and secret friends. This complete guide covers the very best matches and worst matches for every single sign.
A word of honesty before the charts: Chinese zodiac compatibility is folklore and cultural tradition, not science. No controlled study has ever shown that birth years predict how happy a couple will be.
Treat the tables below as a lens for reflection and a starting point for good conversations, not as a verdict on your relationship.
In this guide, you will find the four trine groups explained, a best-matches table covering all twelve animals, a challenging-matches table covering all twelve opposing pairs, the six harm pairs the other tables skip, and the full 12 by 12 matrix with all 78 pairings, plus practical advice for using these charts wisely.
What zodiac compatibility means in Chinese astrology
In Chinese astrology, compatibility is not judged sign by sign at random. It follows two fixed rules that have been used for centuries. The first rule is the trine : the twelve animals divide into four groups of three, and animals in the same group are considered natural allies.
The four trines are Rat, Dragon, and Monkey ; Ox, Snake, and Rooster ; Tiger, Horse, and Dog ; and Rabbit, Goat, and Pig .
People born in the same trine are said to share core values and rhythms, so their relationships, romantic or otherwise, tend to feel easy from the start. The second rule is opposition : each animal sits directly across the wheel from exactly one other animal, six places away.
These opposing pairs, Rat and Horse, Ox and Goat, Tiger and Monkey, Rabbit and Rooster, Dragon and Dog, Snake and Pig , are traditionally considered the most challenging combinations, because their instincts pull in opposite directions.
Everything in the tables below follows these two rules. If a pairing looks unfamiliar, check which trine or opposition it belongs to. The logic is always the same.
What the tool shows
Enter two dates of birth above and the tool finds both animals, using the real Lunar New Year date for each year, then reads the pair from the wheel. It gives five possible outcomes, each with a score:
| Outcome | Score | What the tool says |
|---|---|---|
| Same trine (San He) | 95% | Traditionally a very good match |
| Secret friends (Liu He) | 90% | Traditionally a supportive match |
| Same animal | 75% | Familiar and easy-going |
| No special relationship | 60% | Neutral: it depends on the people |
| Direct clash (Liu Chong) | 35% | Traditionally a challenging match |
The score is a traditional shorthand, not a measurement. A 95% trine pair still needs kindness and effort, and a 35% clash pair can thrive when both people understand their differences. Every result carries the note that Chinese zodiac compatibility describes traditional tendencies, not destinies.
Two honest limits of the tool. First, it reads harm pairs as neutral: the six harm pairs below score 60% here, because the tool only knows trines, secret friends, clashes and same-animal pairs.
Second, it only accepts dates from 1900 to 2099, and it tells you so if you enter anything outside that range, instead of guessing. That is better than the finder, which silently falls back to the calendar year outside its table.
The four trine groups explained
Each trine is sometimes called a “triangle of affinity.” Animals in the same triangle share temperament and priorities, which is why their pairings consistently top compatibility charts.
| Trine (triangle) | Animals | Shared traits |
|---|---|---|
| The action triangle | Rat, Dragon, Monkey | Clever, ambitious, and socially magnetic. This trio loves achievement, new ideas, and being where the action is. Relationships here are energetic, inventive, and rarely boring. |
| The intellect triangle | Ox, Snake, Rooster | Steady, precise, and hardworking. These three value loyalty, honesty, and doing things properly. Bonds here are built on trust, routine, and quiet mutual respect. |
| The independence triangle | Tiger, Horse, Dog | Freedom-loving, idealistic, and spirited. This group bonds over adventure, strong convictions, and loyalty to their own code. Passion runs high, and so does the need for personal space. |
| The diplomacy triangle | Rabbit, Goat, Pig | Gentle, artistic, and compassionate. These three prize harmony, comfort, and kindness. Relationships here are tender, nurturing, and built around a peaceful home life. |
Notice the pattern: each animal’s two most compatible partners are always its two trine-mates. That single rule generates the entire best-matches table below.
Best matches for all 12 animals
Here is every animal with its top two most compatible signs, straight from trine logic, plus its secret friend, the quieter one-on-one alliance, and why the pairing traditionally works.
| Your animal | Best matches | Secret friend | Why it works |
|---|---|---|---|
| Rat | Dragon, Monkey | Ox | The Dragon’s grand ambitions get a clever strategist in the Rat, and the Monkey matches the Rat wit for wit, a playful, inventive partnership full of ideas. |
| Ox | Snake, Rooster | Rat | The Snake brings intuition and depth to the Ox’s steady loyalty, while the Rooster shares the Ox’s work ethic and honesty, a dependable, orderly team. |
| Tiger | Horse, Dog | Pig | The Horse shares the Tiger’s love of freedom and adventure, and the Dog’s loyalty and sincerity ground the Tiger’s intensity with shared idealism. |
| Rabbit | Goat, Pig | Dog | The Goat’s creativity and the Rabbit’s diplomacy create a peaceful, artistic bond; the Pig adds warmth, generosity, and easy affection. |
| Dragon | Rat, Monkey | Rooster | The Rat’s cleverness turns the Dragon’s big visions into results, and the Monkey’s inventiveness makes this a bold, dynamic, fun-loving power pair. |
| Snake | Ox, Rooster | Monkey | The Ox offers calm loyalty that the private Snake trusts, and the Rooster’s precision and observant nature earn the Snake’s deep respect. |
| Horse | Tiger, Dog | Goat | The Tiger matches the Horse’s energy and independence stride for stride, while the Dog brings warm, honest steadiness to the Horse’s lively spirit. |
| Goat | Rabbit, Pig | Horse | The Rabbit’s tenderness and the Goat’s creativity make a harmonious, nurturing bond; the Pig adds kindness and a shared love of comfort. |
| Monkey | Rat, Dragon | Snake | The Rat and Monkey are two quick minds who never run out of things to laugh about; the Dragon gives the Monkey’s inventiveness a grander stage. |
| Rooster | Ox, Snake | Dragon | The Ox’s diligence and honesty make this a hardworking, dependable duo; the Snake adds thoughtful depth and refined mutual understanding. |
| Dog | Tiger, Horse | Rabbit | The Tiger shares the Dog’s protective idealism and courage, while the Horse brings warmth and spirit, steady affection with room to roam. |
| Pig | Rabbit, Goat | Tiger | The Rabbit’s gentleness and the Pig’s generosity build a cozy, family-centered bond; the Goat adds artistry, kindness, and mutual tenderness. |
Secret friends: the quiet alliances
Beyond the four trines, tradition recognizes six “secret friend” pairings, quiet alliances said to bring steady mutual support: Rat and Ox, Tiger and Pig, Rabbit and Dog, Dragon and Rooster, Snake and Monkey, and Horse and Goat.
Unlike trine matches, which sparkle with shared energy, secret-friend pairs are described as calm, loyal partnerships where each partner quietly covers the other’s weaknesses. Many traditional matchmakers valued these pairings as highly as trine matches, especially for long-term stability.
The Great Race myth explains the most famous one: the Rat won by riding the Ox’s back, then jumping ahead at the finish, as told in the Britannica account of the zodiac myth.
Challenging matches: the opposing pairs
Each animal has exactly one opposing sign, six places away on the zodiac wheel. Tradition flags these six pairings as the most likely to produce friction, because the two animals’ instincts pull in opposite directions. Read them as friction themes to navigate , not as predictions of failure.
| Pairing | Where the friction comes from | What helps |
|---|---|---|
| Rat × Horse | The Rat plans carefully and guards resources; the Horse acts on impulse and needs freedom. The Rat can see the Horse as reckless, while the Horse can see the Rat as controlling. | Agree explicitly on how much spontaneity, and how much saving, the relationship holds. |
| Ox × Goat | The Ox is pragmatic and emotionally reserved; the Goat is sensitive and needs reassurance. The Ox’s bluntness can wound the Goat, and the Goat’s moodiness can frustrate the Ox. | Name feelings early and soften feedback; steadiness can be a gift when it is gentle. |
| Tiger × Monkey | The Tiger is proud and straightforward; the Monkey is clever and loves to tease. The Tiger can feel its dignity is being mocked, while the Monkey feels bossed around. | Respect each other’s style of humor, and the Tiger’s need to be taken seriously. |
| Rabbit × Rooster | The Rabbit avoids conflict and values tact; the Rooster is direct and freely critical. The Rabbit can feel attacked by “helpful” criticism the Rooster believes is simply honest. | Softer delivery on one side, thicker skin on the other; schedule calm check-ins. |
| Dragon × Dog | The Dragon is grand, optimistic, and prideful; the Dog is cautious and skeptical. The Dog’s worry can feel like pessimism, and the Dragon’s risk-taking can feel unsafe. | Shared goals help: the Dog plans the safety net while the Dragon leads the charge. |
| Snake × Pig | The Snake is private, intense, and slow to trust; the Pig is open, trusting, and sociable. The Snake can feel exposed by the Pig’s openness, while the Pig feels shut out by the Snake’s secrecy. | Allow different paces of trust; the Pig’s warmth usually coaxes the Snake open in time. |
Plenty of lasting, happy couples are opposing pairs. The tradition itself treats opposition as a challenge to work through with awareness, and couples who understand their friction points often communicate better than “perfect matches” who never examine theirs.
Harm pairs: the quieter friction
Below the clash level sit the Liu Hai harms, six secondary slow-friction pairs. They are not clashes: the friction builds gradually rather than arriving at once, which is why they are easy to miss.
The tool does not use them; it reads a harm pair as neutral and gives it 60%. The deeper BaZi tables name them, so they are listed here for completeness.
| Pairing | Where the friction comes from | What helps |
|---|---|---|
| Rat × Goat | The Rat plans and guards resources; the Goat feels its way and needs reassurance. The Rat can see the Goat as impractical, while the Goat can see the Rat as cold. | Name feelings early; the Rat’s steadiness is a gift when it is gentle. |
| Ox × Horse | The Ox is steady and routine-bound; the Horse needs freedom and movement. The Ox can see the Horse as restless, while the Horse can see the Ox as rigid. | Agree on how much routine and how much roaming the relationship holds. |
| Tiger × Snake | The Tiger is proud and straightforward; the Snake is private and slow to trust. The Tiger can feel shut out by the Snake’s secrecy, while the Snake can feel crowded by the Tiger’s intensity. | Give the Snake room to open up in its own time; the Tiger’s directness is a gift when it is patient. |
| Rabbit × Dragon | The Rabbit avoids conflict and values tact; the Dragon is grand and direct. The Rabbit can feel overwhelmed by the Dragon’s scale, while the Dragon can feel the Rabbit is holding back. | Smaller plans, honestly discussed, suit this pair better than grand gestures. |
| Monkey × Pig | The Monkey is clever and loves to tease; the Pig is open and trusting. The Monkey can see the Pig as naive, while the Pig can feel the Monkey is not taking things seriously. | The Monkey’s humour lands better when the Pig knows it is affection, not mockery. |
| Rooster × Dog | The Rooster is direct and freely critical; the Dog is cautious and loyal. The Rooster’s criticism can feel like an attack on the Dog’s loyalty, while the Dog’s worry can feel like pessimism. | Criticism aimed at the plan, not the person, keeps this pair steady. |
The full 12 by 12 matrix
Every pair of animals is one of six things. Find the first animal down the side and the second across the top. T means same trine, the best match. F means secret friends, the quiet alliance. C means direct clash, the hardest pairing.
H means a harm pair, the quieter friction. S means the same animal. A dash means neutral: the pair has no special relationship in the traditional system, which is not the same as getting along badly.
| Rat | Ox | Tiger | Rabbit | Dragon | Snake | Horse | Goat | Monkey | Rooster | Dog | Pig | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Rat | S | F | – | – | T | – | C | H | T | – | – | – |

| Dog | – | – | T | F | C | – | T | – | – | H | S | – |
| Pig | – | – | F | T | – | C | – | T | H | – | – | S |
The matrix covers all 78 unique pairings: 66 between different animals plus 12 same-animal pairs. Counted by type, that is 12 trine pairs, 6 secret-friend pairs, 6 clashes, 6 harm pairs, 12 same-animal pairs and 36 neutral pairs.
The tool gives the same reading for any pair you enter: trine 95%, secret friends 90%, same animal 75%, neutral 60%, clash 35%. Harm pairs are the one exception: the matrix marks them H, but the tool reads them as neutral and gives 60%.
How to use Chinese zodiac compatibility
Follow these steps to get a reading you can actually use: Confirm both animals first. Use our free Chinese zodiac finder to look up both birth dates: it accounts for the Lunar New Year boundary, which trips up everyone born in January or February.
Our Chinese zodiac by birth year guide explains the boundary trap in detail. Find each person’s trine. Sharing a triangle means natural affinity; different triangles mean you will need to translate between different temperaments.
Check for an opposing pair. If you land on one of the six oppositions above, read its friction theme as a discussion starter, not a warning label. Layer in the five elements.
Each birth year pairs its animal with one of the five elements, Wood, Fire, Earth, Metal or Water, which adds a second dimension: a Water sign traditionally nourishes a Wood sign, for example. See the elements section of our birth-year guide for the full cycle.
Add the Western lens if you like. Many readers enjoy comparing both systems: find your Western sign in our what is my zodiac sign guide and see how the two traditions describe you differently.
Compatibility is a lens, not a verdict
Here is the honest bottom line the tradition itself supports: charts describe tendencies, not destinies. A “best match” pairing still requires kindness, honesty, and effort, and a “challenging” pairing can thrive when both people understand their differences and talk about them openly.
Use Chinese zodiac compatibility the way it was meant to be used: as a starting lens for curiosity about another person, a prompt for better conversations, and a bit of cultural fun.
The quality of a relationship is decided by communication, respect, and shared values, which no chart can measure and no animal sign can replace.
Decode Any Pair in 3 Steps
Compatibility matrices dump a 12×12 grid and leave. Here is the method behind the grid, worked through two pairs.
Example 1: Rat + Horse
Step 1, same trine? Rat is in Rat-Dragon-Monkey; Horse is in Tiger-Horse-Dog. No. Step 2, secret friends (Liu He)? Rat pairs with Ox; Horse pairs with Goat. No. Step 3, clash (Liu Chong)? Rat-Horse are opposites, six apart on the wheel. Yes, direct clash. Verdict: approach thoughtfully. The clash pairing asks for conscious effort.
Example 2: Dog + Tiger
Step 1, same trine? Both are in Tiger-Horse-Dog. Yes. Verdict: traditionally favorable. Same-trine pairs share independence and energy.
The Three Compatibility Layers
San He: Three Harmonies (trines)
Four trines of signs four apart on the wheel: Rat-Dragon-Monkey (ambition and drive), Ox-Snake-Rooster (patience and planning), Tiger-Horse-Dog (independence and energy), Rabbit-Goat-Pig (kindness and domestic comfort). The strongest long-term matches.
Liu He: Six Harmonies (secret friends)
One complementary pair per sign: Rat-Ox, Tiger-Pig, Rabbit-Dog, Dragon-Rooster, Snake-Monkey, Horse-Goat. The Great Race myth explains the most famous one: Rat won by riding the Ox’s back, then jumping ahead at the finish.
Liu Chong: Six Clashes
Opposite pairs, six apart: Rat-Horse, Ox-Goat, Tiger-Monkey, Rabbit-Rooster, Dragon-Dog, Snake-Pig. Below the clash level sit Liu Hai harms, secondary slow-friction pairs: Rat-Goat, Ox-Horse, Tiger-Snake, Rabbit-Dragon, Monkey-Pig, Rooster-Dog.
The four-apart, six-apart rule
Four years apart on the wheel means trine (compatible). Six apart means clash. One sentence decodes any pair. Signs in neither column are neutral, not bad, a nuance most guides skip.
Why the year animal is only the first filter
The year animal is one of four pillars in BaZi, the Four Pillars system: year, month, day and hour. This calculator uses the year animal only, which is why it is a first filter rather than a full reading.
The day pillar in particular says more about relationships than the year animal does, because it describes the person themselves rather than the year they were born into.
A full BaZi reading adds the month, day and hour pillars, and two people who clash on the year animal can still read well on the day pillar.
The 60-year stem-branch cycle behind the pillars is described in the Metropolitan Museum of Art’s Chinese zodiac collection, which traces the animal order to the Eastern Han dynasty.
The current year is an example: 2026 is a Fire Horse year (Bing-Wu), which began on 17 February 2026, as Sydney University’s Lunar New Year coverage notes. None of that changes the year-animal reading above; it puts it in its place.
What other Chinese zodiac compatibility calculators offer
Most Chinese zodiac compatibility calculators on the first page read the same trines and clashes, so what sets them apart is what else they show. Here is where this page stands against the three that rank highest for the same query.
| Feature | Age-Finder | JadeAlmanac | TheAstroscope | ZodiacTales |
|---|---|---|---|---|
| Two-date calculator | Yes | Yes | Yes | Yes |
| Compatibility score | Yes, 35% to 95% | Not shown | Yes, 48% to 92% | Yes, 38 to 98 |
| Trine matches | Yes | Yes | Yes | Yes |
| Secret friends | Yes | Yes | Yes | Yes |
| Clash pairs | Yes | Yes | Yes | Yes |
| Harm pairs | In the guide, not the tool | Yes | Yes | Not shown |
| Full 12 by 12 chart | In the guide, not the tool | Yes, 144 pairings | Yes, 78 pairings | Yes, 78 pairings |
| Family mode | No | Not shown | Not shown | Yes |
| BaZi and day-pillar framing | Yes, in the guide | Not shown | Not shown | Not shown |
| Free, no sign-up | Yes | Yes | Yes | Yes |
What the tool cannot do yet: it reads harm pairs as neutral, it gives no element reading, and it has no 12 by 12 chart. What it adds is the score, the honest range error, and the matrix and harm tables worked through by hand in the guide.
Frequently Asked Questions
What are “secret friends” in Chinese zodiac compatibility?
Beyond the four trines, tradition recognizes six “secret friend” pairings, quiet alliances said to bring steady mutual support: Rat and Ox, Tiger and Pig, Rabbit and Dog, Dragon and Rooster, Snake and Monkey, and Horse and Goat.
Unlike trine matches, which sparkle with shared energy, secret-friend pairs are described as calm, loyal partnerships where each partner quietly covers the other’s weaknesses. Many traditional matchmakers valued these pairings as highly as trine matches, especially for long-term stability.
Do the five elements change a compatibility reading?
Yes, the elements add a second layer on top of the animal pairing. Each birth year pairs one animal with one element from a set of five, Wood, Fire, Earth, Metal and Water, and the pairing repeats every 60 years.
The elements follow their own generating order: Wood to Fire, Fire to Earth, Earth to Metal, Metal to Water, and Water back to Wood.
A generating-element pairing (for example, a Water Rat with a Wood Dragon) is traditionally read as extra harmonious, while a controlling-cycle pairing (such as Water dousing Fire) can add friction even between otherwise compatible animals. Two people with the same animal but different elements can therefore have noticeably different dynamics.
Can two people with the same animal sign be compatible?
Traditionally, yes, same-sign pairs are considered workable and sometimes excellent. The logic is simple: you share instincts, so you intuitively understand each other. The catch is that you also share blind spots, so the pairing amplifies both strengths and weaknesses.
Two Dogs, for example, are famously loyal together but can reinforce each other’s anxieties; two Tigers must manage competing pride. Same-sign couples are often advised to consciously cultivate the qualities their shared sign lacks.
Does Chinese zodiac compatibility apply to friendships and business, or only romance?
It applies broadly. The trine and opposition system originally described alliances of all kinds: business partnerships, friendships, and family relationships as much as marriages.
A Rat-Dragon-Monkey trio, for instance, is traditionally considered a strong founding team for a venture, and parents have long consulted the charts for family harmony. If you are evaluating a business partner or a close friendship, read the same tables with “partnership” in mind rather than romance.
Is compatibility read the same everywhere the zodiac is used?
Mostly, but with one famous exception: in Vietnam, the Cat replaces the Rabbit in the zodiac. Vietnamese compatibility charts therefore pair the Cat wherever Chinese charts pair the Rabbit, so the Rabbit-Rooster opposition becomes a Cat-Rooster opposition, and the Rabbit’s trine partners (Goat and Pig) become the Cat’s.
The underlying trine-and-opposition logic is identical; only the animal in that one slot changes. It is a good reminder that these systems are living cultural traditions with regional variations, not fixed laws.
What score does the calculator give?
The calculator gives a score from 35% to 95%: 95% for a same-trine pair, 90% for secret friends, 75% for the same animal, 60% for a neutral pair, and 35% for a direct clash.
The score is a traditional shorthand, not a measurement; the tables above explain what each score means. Harm pairs score 60% here, because the tool reads them as neutral.
