Should Hour Pillar Be Considered in Marriage Matching?

Deep Oracle Practitioner Desk · 2026-09-19 · 6 min read

Hehun, or marriage compatibility assessment, asks whether the hour branch must be included when comparing two birth charts. The short answer is that it should be included whenever it is known, because the hour pillar is one of the four pillars and participates in the same cross-chart comparisons as the year, month, and day pillars. When the hour is uncertain, the practical task is not to force a single hour, but to record the uncertainty and keep the comparison honest.

四柱里时柱占的是哪一格

A complete bazi consists of four pillars: the year pillar, month pillar, day pillar, and hour pillar. Each pillar is made up of a heavenly stem and an earthly branch. The hour pillar is derived from the time of birth, so when the birth hour is missing, only three pillars remain. In that situation the chart is not being read as a full four-pillar chart; it is a three-pillar chart with a known gap.

The hour pillar is not a minor detail appended to the day pillar. It is one column among four equal columns. Its stem and branch form their own pair, and that pair can combine, clash, harm, or otherwise interact with stems and branches elsewhere in the same chart and in the other person’s chart. For the purpose of hehun, losing the hour pillar means losing one of the four columns that would otherwise be compared.

时辰缺失后还能比较哪几项

When the hour pillar is absent, the remaining comparisons are drawn from the year, month, and day pillars of each chart. This still allows the year branches to be compared, the month branches and stems to be compared, and the day stems and day branches to be compared. It also allows interactions between one person’s year or month pillar and the other person’s day pillar to be examined.

What disappears is every interaction that involves either person’s hour stem or hour branch. That includes direct hour-to-hour comparisons, such as one hour branch clashing the other hour branch. It also includes indirect comparisons, such as one person’s hour branch combining with the other person’s month branch, or one person’s hour stem entering a heavenly stem combination with the other person’s day stem.

Because the hour pillar is one of four columns, its absence removes roughly one quarter of the surface area available for cross-chart comparison. This does not mean the remaining three quarters are useless. It means the result is partial, and any conclusion drawn from it should be stated as a conclusion about the known three pillars, not about the full four-pillar relationship.

时辰误差落在哪一层

If the birth hour is recorded but may be wrong, the error usually sits at the boundary between two hour branches. The traditional twelve double-hours divide the day into sections, but civil clock time does not always match the time standard used for chart erection. A birth recorded near the edge of a double-hour may belong to the previous or the following hour branch once the time correction is applied.

The two most common sources of error in erecting a chart are the solar-term boundary and true solar time. The solar-term boundary affects the month pillar, not the hour pillar, but it is mentioned here because it is one of the two places where a chart is most likely to be built incorrectly. True solar time affects the hour pillar directly. Clock time is a civil convention, while the hour branch is assigned according to the position of the sun at the birthplace. A birth recorded at 13:05 by the clock may fall before or after the true solar noon boundary depending on longitude and the equation of time.

When the recorded hour is close to a boundary, the chart may shift by one hour pillar. That shift changes not only the hour branch but also the hour stem, because the stem is assigned from the day stem and the hour branch together. A one-branch change can therefore alter two characters at once, and every interaction involving those characters changes with it.

Traditional hehun does not stop at the day pillar. A common but narrow reading treats the day branch as the only relevant point of comparison, but the broader method brings in multiple layers. Those layers include the month command, the year pillar, and the hour pillar. The month command matters because it sets the seasonal frame within which each chart operates. The year pillar matters because it carries the larger environmental and ancestral frame. The hour pillar matters because it represents the later stage and the private or inward direction of a person’s chart.

In practice, the comparison is not one point against one point. It is a set of interactions across two charts. The month branches of the two charts may form a combination or a clash. The year branches may show a relationship of support or pressure. The day stems may show whether the two people’s self-elements have a generating or controlling tendency. The hour pillars may show how the two charts meet at the level of later-life direction, private disposition, or hidden output.

Because all four pillars are read together, the hour pillar is not an optional add-on. It is one of the layers through which the two charts touch. When the hour pillar is missing, one whole layer of that comparison is unavailable. The remaining layers can still be read, but the reading is thinner than a full hehun reading.

时辰不确定时的写法

When the birth hour is uncertain, the correct practice is to state a candidate range and keep the candidate charts open. Do not choose one hour on the spot merely to make the chart look complete. A chart erected from a guessed hour presents itself as a four-pillar chart, but it may be the wrong four-pillar chart, and every comparison built on it inherits that uncertainty.

The safer notation is to record the possible range, such as a birth between the Wei hour and the Shen hour, and to keep both candidate charts for comparison. If one candidate chart gives a certain relationship and the other gives a different one, that difference is itself information. It tells the reader which conclusions are stable across the range and which conclusions depend on the hour.

The same rule applies when the recorded hour is exact but close to a true solar time boundary. In that case the candidate range may be narrow, but it still exists. The chart should be checked against true solar time before the hour pillar is treated as settled.

For hehun specifically, the uncertainty notation matters because the hour pillar enters cross-chart interactions. If one person’s hour is unknown, the comparison of that person’s chart to the other person’s chart is incomplete. If both hours are unknown, the comparison loses the entire hour layer on both sides. The remedy is not to invent a layer, but to mark it as missing.

The platform provides a merged chart output for two people. This output includes the four pillars of both sides, the ten gods, and the five-element complementarity between the two charts. When both charts are complete, the merged output shows the full set of comparisons, including the hour layer. When one or both hour pillars are missing or uncertain, the merged output should be read with that gap stated, so that the reader sees which parts of the comparison are present and which parts are not.
