Traditional matching reads the Six Harmony pairs (Rat–Ox, Tiger–Pig, Rabbit–Dog, Dragon–Rooster, Snake–Monkey, Horse–Goat) and signs of the same trine (Monkey–Rat–Dragon, Tiger–Horse–Dog, Pig–Rabbit–Goat, Snake–Rooster–Ox) as the closest Chinese zodiac matches. The six Clash pairs (Rat–Horse, Ox–Goat, Tiger–Monkey, Rabbit–Rooster, Dragon–Dog, Snake–Pig) sit opposite each other on the zodiac circle and are read as needing give-and-take. Every pair has its own reading, with no percentage score.
Open the calculator above and choose a one-sign lookup or a two-sign comparison. Select the animals, then view the result. In the one-sign view, choosing a pairing opens its explanation. You can read the table below without entering any information.
The six traditional pairs are Rat–Ox, Tiger–Pig, Rabbit–Dog, Dragon–Rooster, Snake–Monkey and Horse–Goat. The Three Harmony groups are Monkey–Rat–Dragon, Tiger–Horse–Dog, Pig–Rabbit–Goat and Snake–Rooster–Ox. OpenFate calls a two-sign connection a Half Trine when it includes the group’s middle branch: Rat, Horse, Rabbit or Rooster. Tiger–Dog, for example, shares a group but is not labelled a Half Trine.
Clashes pair opposite branches, such as Rabbit–Rooster. Harm uses a different set of pairs, such as Rabbit–Dragon; Break includes pairs such as Rabbit–Horse. These names have different meanings within the tradition. A result can list more than one relation, and the tool does not subtract one from another or turn them into a ranking.
Tiger–Snake–Monkey and Ox–Goat–Dog are three-branch punishment groups. When two selected signs belong to one group, the result says “Two of a punishment trio” and identifies the missing member. Rat–Rabbit is a separate punishment pair. Repeated Dragon, Horse, Rooster or Pig signs carry the traditional Self-punishment label; the other repeated signs do not.
OpenFate checks whether the principal Heavenly Stems hidden in the two branches form a stem combination. This convention produces connections such as Tiger–Ox and Rabbit–Monkey. Some schools use a different definition of Hidden harmony, so compare the stated method when another website gives a different result.
The BaZi year changes at Li Chun, a solar term in early February. The lunar calendar changes years at Lunar New Year. These boundaries can fall on different dates. This tool uses the animals you select; it does not check your birthday. If your sign is uncertain, use the free BaZi chart with your recorded birth date, local time and birthplace, then return with the Year Branch shown there.
A birth-year pairing leaves out the Month, Day and Hour Pillars. A full BaZi relationship comparison can examine both charts and their timing context within the tradition. More chart detail does not make a marriage prediction certain. Discuss communication, consent, responsibilities and shared plans using what you know about the actual relationship.

Answers about traditional matches, birth-year boundaries and what this free calculator can show.
Find your animal’s row in the chart above: its Six Harmony partner and its Half Trine partners are the matches tradition reads as closest. A favourable year-branch label does not establish that two particular people will get along.
The six opposite pairs are Rat–Horse, Ox–Goat, Tiger–Monkey, Rabbit–Rooster, Dragon–Dog and Snake–Pig. They are called Clashes. OpenFate shows the relation without declaring these the worst couples or predicting separation.
Same-sign pairs share a Year Branch, which is read as caring about the same things and moving at the same pace. Dragon, Horse, Rooster and Pig also receive a Self-punishment label under this rule set. Neither label decides whether a couple should date or marry.
It has not been shown to predict personality or relationship outcomes. The pairing rules can be checked and reproduced, which makes a result consistent, not predictive. Use it as traditional cultural material and a conversation prompt.
Yes. Each animal returns every 12 years, and every pair page lists both signs’ birth years from 1936 to 2031. The calculator itself asks for the animals, not dates. If you were born in January or early February, check your BaZi Year Pillar first, because the BaZi year changes at Li Chun. Check your BaZi Year Pillar
Yes. Both the one-sign lookup and two-sign comparison are free and require no login. Full BaZi readings are separate features with their own access and pricing.
Yes. The branch-pair rules do not change with the relationship role. Use the interpretation with your own context, and do not use zodiac signs to judge someone’s parenting, job suitability or trustworthiness.
Not at the zodiac level. Harmony, Clash, punishment, and Harm all come from the two birth-year branches, so the relationship is the same whichever of you is the man. Pages that split “Ox man, Snake woman” from “Ox woman, Snake man” are usually layering traditional expectations of husbands and wives on top. What really differs from person to person is the Day Pillar and Spouse Palace in a Bazi chart, which only full birthdays can show.
Part of this old belief can actually be worked out. Two signs born 6 years apart are always a Clash. Of the twelve combinations 3 (or 9) years apart, ten carry a punishment, Harm, or Break; among them, Tiger–Pig and Snake–Monkey are also Six Harmony, while Dragon–Goat and Horse–Rooster have no harmony or clash at all. On the other hand, two signs 4 (or 8) years apart always come from the same trine. An age gap just happens to line up with a particular sign relationship, so look at the pair you actually are; every pair’s reading includes an age-gap guide.
Some families really do this. An Ox and Snake couple, for example, might wait for a Rooster year to complete the Snake–Rooster–Ox trine. A trine means heading the same way, so it’s traditionally a good sign, but a child’s sign is only their birth-year branch, and the bond between parent and child is built day by day. If you were already planning and it happens to line up, that’s a nice bonus. There’s no need to move your plans earlier or later for a sign; being ready in health, work, and finances matters more.
For zodiac compatibility, yes: only the year branch counts, and both are Chou, the Ox. Articles on “which Ox year goes best with which Snake year” usually add the year’s heavenly stem and its nayin element on top. For example, 1985 is Yi Chou, a Wood Ox, and 1997 is Ding Chou, a Fire Ox, and their nayin differ. That’s a separate layer of the Bazi Year Pillar; for a fuller picture, put both birthdays into Bazi charts and look at the Day Pillar and Spouse Palace.
