The Four Core Rules of Chinese Zodiac Compatibility
San He — Triple Harmony (三合)
The twelve signs form four groups of three, each linked to an element: Monkey–Rat–Dragon (Water), Pig–Rabbit–Goat (Wood), Tiger–Horse–Dog (Fire) and Snake–Rooster–Ox (Metal). Signs in the same group are traditionally seen as natural allies.
Liu He — Six Harmonies (六合)
Six pairs "combine": Rat–Ox, Tiger–Pig, Rabbit–Dog, Dragon–Rooster, Snake–Monkey and Horse–Goat. These are often called secret friends.
Xiang Chong — Six Conflicts (六冲)
Signs directly opposite each other clash: Rat–Horse, Ox–Goat, Tiger–Monkey, Rabbit–Rooster, Dragon–Dog, Snake–Pig.
Xiang Hai — Six Harms (六害)
Rat–Goat, Ox–Horse, Tiger–Snake, Rabbit–Dragon, Monkey–Pig and Rooster–Dog are the harm pairs. The calculator also checks the punishment (刑) groups and the destruction (破) pairs.

Frequently asked questions
How does the Chinese Zodiac compatibility calculator work?
It finds each person's animal sign — from the birth date (checking the Lunar New Year and Li Chun boundary) or from the sign you select — and then checks the traditional earthly-branch relations between the two signs: Six Harmonies (Liu He), Triple Harmony (San He), clash, harm, punishment and destruction.
Which Chinese Zodiac signs are the best matches (San He and Liu He)?
The Six Harmonies pairs are Rat–Ox, Tiger–Pig, Rabbit–Dog, Dragon–Rooster, Snake–Monkey and Horse–Goat. The Triple Harmony groups are Monkey–Rat–Dragon, Pig–Rabbit–Goat, Tiger–Horse–Dog and Snake–Rooster–Ox. Some pairs also carry a conflict-type relation (for example, Snake–Monkey is also a punishment and destruction pair), and the calculator lists all of them.
Which Chinese Zodiac signs should avoid each other (Six Conflicts)?
The six clash pairs are the signs opposite each other on the zodiac circle: Rat–Horse, Ox–Goat, Tiger–Monkey, Rabbit–Rooster, Dragon–Dog and Snake–Pig. Tradition reads them as opposite temperaments that need more effort, not as pairs that cannot work.
Why do I need my exact birth date instead of just my birth year for January/February birthdays?
The zodiac year changes at Lunar New Year (between January 21 and February 20) or, in the solar tradition, at Li Chun (around February 4) — not on January 1. Someone born on January 15, 1995 is a Dog (1994), not a Pig. This calculator uses Lunar New Year as its primary standard. If your birth date falls between the two boundaries, it shows the Lunar New Year result first and the Li Chun result next to it for comparison.
Does the calculator give a compatibility percentage?
No, by design. The result is the traditional relations between the two signs (Six Harmonies, Triple Harmony, clash, harm, punishment, destruction) and a qualitative tier label. The site does not turn these into percentages, star ratings or numeric scores. The calculator does not write a separate reading for each of the 144 sign pairs.
