Compatibility calculator · result explained

What does “no named pair” mean in Chinese zodiac compatibility?

It means this calculator found neither a Six Harmonies pair nor a Six Clashes pair for the two lunar-year animals. It does not mean the two people are incompatible, average, or destined for any outcome. This tool checks two named pair lists; it does not score a relationship.

Among 66 different-animal pairs, this calculator labels 6 Six Harmonies, 6 Six Clashes, and 54 neither. Identical-animal pairs are handled separately. — A count of the distinct animal pairs covered by this site's current code, not a statistic about real relationships.

Why most pairs get this result

There are 12 lunar-year animals. Ignoring order, two different animals can make 66 pairs: 12 × 11 ÷ 2. The site's code names six traditional harmonies and six traditional clashes. The other 54 different-animal pairs receive “Neither harmony nor clash.” A pair of the same animal is handled first and receives “Same lunar-year animal.” These counts come from this site's current pairing function, not from a claim that tradition has only two kinds of animal relationship.

First identify each lunar-year animal from a full birth date; then check same animal, six harmony pairs, six clash pairs, and finally neither list. — The label follows a limited lookup after each full birth date has been resolved to a lunar-year animal.

Four results you can reproduce

Enter the dates below in the compatibility calculator. Each July date is after its year's lunar New Year, so the animal shown is unambiguous under this site's rule.

First date	Second date	Animals	This site's label
July 1, 1984	July 1, 1985	Rat + Ox	Six Harmonies
July 1, 1984	July 1, 1990	Rat + Horse	Six Clashes
July 1, 1984	July 1, 1987	Rat + Rabbit	Neither harmony nor clash
July 1, 1984	July 1, 1996	Rat + Rat	Same lunar-year animal

Four tested labels with a fixed Rat: Ox is Six Harmonies, Horse is Six Clashes, Rabbit is neither list, and Rat is the same-animal case. — Keeping Rat fixed makes the four possible outputs easy to compare.

What “no named pair” does not say

It is not a negative compatibility rating. The two lists used here are the traditional Earthly Branch Six Harmonies and Six Clashes recorded in Shandong University of Technology's relationship notes. That same source describes other branch relations, including harm and punishment, which this simple tool does not calculate. Adding those ideas would require a separately defined method; a missing label here must not be interpreted as “no relation in every tradition.”

These are cultural categories, not measured facts about two people. A harmony label cannot guarantee a good relationship, and a clash label cannot predict a bad one. For the exact scope of another result field, see whether the five elements change this site's pair label.

Quick answers

Is “no named pair” a bad result?

No. It only means the pair is absent from the two lists this calculator checks. See the complete 12-sign lookup table to inspect every cell under these rules.

Does it mean the animals have no traditional relationship at all?

No. This tool does not implement every Earthly Branch relation. It cannot answer that broader question.

Why did my pair change when I entered full dates?

A January or February birth may belong to the previous lunar year. The two animals can change when the complete dates are compared with Chinese New Year; see our worked date examples.
