Marriage Compatibility Taboos: Zodiac, Day Pillar, and Calendar

The term 合婚禁忌 refers to a set of popular restrictions and warnings surrounding the assessment of a couple’s compatibility in traditional Chinese practice. These restrictions circulate mainly in folk contexts and are often presented as rules for what should be avoided when checking a proposed marriage. The material below distinguishes between what is commonly repeated, what can actually be checked, and what lacks any clear basis.

流传的禁忌大致有哪几类

In popular circulation, the prohibitions associated with 合婚 are usually grouped into three broad types. The first type involves pairings based on the earthly branch of the year of birth, especially when the zodiac signs are said to clash or harm one another. Common examples include pairings between 子 and 午, or between 丑 and 未, where the two branches are placed in direct opposition. Such pairings are often described as unsuitable simply because the branches stand in a relation of conflict.

The second type concerns the day pillar, specifically the earthly branch of the day of birth. Here the warning is usually expressed in terms of clashes or punishments between the day branches of the two people. A phrase such as 日支相冲不宜 is typical: it states that if the day branches clash, the match is not appropriate. This kind of rule is repeated in many folk manuals and oral traditions, often without further explanation.

The third type involves calendrical labels attached to particular years. Among these labels are 无春年，双春年, and 寡妇年. These are not qualities of the two individuals being matched, but rather names given to years based on how the lunar calendar aligns with the solar terms. A year may be called 无春年 when it contains no beginning-of-spring solar term, or 双春年 when it contains two such terms. 寡妇年 is a popular label with a more alarming tone, but it belongs to the same family of calendrical naming. In folk usage, marriages in such years are sometimes said to be unfortunate.

禁忌与合婚方法的关系

The relationship between these taboos and the actual methods of 合婚 is uneven. The year-branch method, which uses only the zodiac sign of the year of birth, has very limited resolving power. A single zodiac sign corresponds to an enormous number of people, since the same earthly branch recurs every twelve years and applies to all births within that year. Reducing the compatibility of two people to the relationship between two branch characters therefore leaves out almost all the information that a fuller analysis would consider. The level of discrimination available from two year branches alone is clearly insufficient.

The calendrical labels operate on a different level. They do not describe the couple at all. Instead, they describe the structure of a calendar year. The names 无春年，双春年, and 寡妇年 arise from the misalignment between the lunar calendar and the solar terms. A lunar year may begin after the beginning-of-spring term or end before the next one, producing a year with no such term. In another year, the term may appear twice. These are results of how the calendar is arranged, not signs carrying inherent good or bad fortune. Treating them as marriage taboos is a separate step, one that is not supported by the calendrical facts themselves.

The day-branch warnings stand apart from both. In the material available to this site, statements such as 日支相冲不宜 are not accompanied by a derivation that can be rechecked, nor are they supported by a body of comparable records. The assertion is made, but the path from the stated clash to the conclusion of unsuitability is not supplied.

哪几类说法查不到依据

Several categories of popular taboo cannot be verified through the method used by this site. The first is the year-branch pairing restriction in its simple form. While the clash or harm relation between two branches can be checked mechanically, the conclusion that the match is unsuitable does not follow from that relation alone. The branch relation is a fact of the calendar, but the judgment attached to it is an additional claim.

The second category is the calendrical label. The existence of a 无春年, a 双春年, or a year labelled 寡妇年 can be confirmed by examining the calendar. What cannot be confirmed is the idea that such a year is bad for marriage. The label describes a structural feature of the year, not an observed pattern of outcomes. The meaning attached to the label is external to the calendrical fact.

The third category is the day-branch warning. The phrase 日支相冲不宜 is a conclusion, but no verifiable derivation is provided. There is no recorded chain from the day-branch clash to a checkable result, and no set of cases against which the claim can be compared. Without such a chain, the statement remains a folk assertion.

By contrast, one item can be checked. The self-punishing earthly branches are 辰，午，酉, and 亥. In a chart comparison, it is possible to show whether the day branches of two people are the same branch, and whether that branch is one of the self-punishing branches. This distinction is a matter of fact: the branch is either the same or it is not, and it either belongs to the listed set or it does not. The output marks this separately. What the output does not do is draw a conclusion from that fact. Whether a same-branch or self-punishing relation makes a match unsuitable is not stated.

一个更实际的处理次序

Given the uneven quality of the popular restrictions, a more practical order of handling is to begin with what can be checked and then set aside what cannot. The first step is to identify the year branches, the day branches, and the calendrical features involved. These can all be listed. The second step is to mark the relations that are mechanically determinable: whether the year branches clash or harm, whether the day branches are the same, whether the day branch is one of 辰，午，酉, or 亥, and whether the year carries one of the calendrical labels.

The third step is to distinguish between the fact and the conclusion. A clash between year branches is a fact. A label such as 寡妇年 is a fact of naming. A same day branch is a fact. The conclusion that a marriage is therefore unsuitable is not a fact and is not derived from the checkable material.

This site outputs the checkable layer. It identifies the branch relations and the calendrical features that can be confirmed from the birth data. It does not output a conclusion about whether the two people are suitable for one another. That judgment is not part of the output. The line drawn here is deliberate: the material that can be rechecked is shown, and the evaluative step that popular tradition attaches to it is left out. In this way, the reader can see what the data supports and what remains outside the range of verification.
