Earthly Branch Six Clashes: How to Identify and Read Bazi Clashes Carefully

一 What it is

What the Six Clashes Are

The Six Clashes are six fixed pairs of Earthly Branches that sit directly opposite each other on the traditional branch cycle. The supplied lookup contains exactly six pairs: 子–午 (Water–Fire opposition), 丑–未 (Earth pair), 寅–申 (Wood–Metal opposition), 卯–酉 (Wood–Metal opposition), 辰–戌 (Earth pair), and 巳–亥 (Fire–Water opposition). Each pair is a fixed relationship, not a judgment. For the underlying framework, see Earthly Branches in Bazi: The Twelve Characters and Their Hidden Stems.

Detection is simple co-presence. If both branches of a pair appear anywhere in the four pillars, the calculator reports a match. In the first example, 子 in the year and 午 in the hour produce one Six Clash. In the second, 子–午 and 辰–戌 produce two. A detected pair means only that all listed characters coexist in the chart.

Detection is not transformation, and it is not prediction. The direction labels above are traditional names for the pair, not proof that either branch changed into something else. The engine keeps every branch and its hidden stems in the raw totals, so a clash does not erase or rewrite what is present. Nor does a clash automatically mean conflict, accident, divorce, or loss; those are interpretations, not outputs of the lookup.

A useful analogy is two magnets placed near each other. Their poles are defined by position, and their presence is a fact you can observe. Whether they pull, push, or simply sit there depends on the whole arrangement around them. Likewise, a Six Clash is a positional fact first; meaning comes later, from the full chart and careful reading.

二 Where to find it in your chart

Where to Inspect the Stem and Branch Rows

Open your Four Pillars result and locate the four columns labelled Year, Month, Day and Hour. Each column holds two rows: the upper row is the Heavenly Stem and the lower row is the Earthly Branch. Read them as pairs, not as isolated symbols. In a chart such as 甲子 / 丁卯 / 甲寅 / 庚午, the Year column pairs stem 甲 with branch 子, the Month column pairs 丁 with 卯, and so on.

Check every branch against the others for a Six Clash: 子–午, 丑–未, 寅–申, 卯–酉, 辰–戌 and 巳–亥. Detection simply means both characters are present somewhere in the four columns. The same character may appear more than once, so a branch can sit in two columns at once. Location and repetition are worth describing, but co-presence alone does not prove conflict, accident, divorce or loss.

If the birth time is unknown, the Hour slot is removed entirely; no Hour Pillar is invented, and only three columns remain for inspection. Year and Month boundaries follow China time, while Day and Hour use true solar time, so the same clock reading can place a character in a different column.

三 How to identify it

How to Identify Earthly Branch Six Clashes

Start with the four branch positions: year, month, day and hour. Each position holds one Earthly Branch. A Six Clash is detected when two branches from the same listed pair are both present in the chart. Detection is co-presence, nothing more. The pair does not need to sit next to each other, and it does not need to appear in any particular order. The method is easier to compare with Earthly Branch Six Combinations: A Practical Guide to the Six Harmonies in Bazi.

Use the lookup table as your only pair list. It contains six entries: 子–午, 丑–未, 寅–申, 卯–酉, 辰–戌 and 巳–亥. Read each entry as a fixed set of two members. If a chart contains 子 and 午 anywhere among its four branches, the 子–午 pair is complete. If it contains only 子, that pair is absent; a single member is not a clash.

Complete and Partial Membership

Complete membership means both listed branches are present. Partial membership means only one of the two appears. Partial membership never triggers a match, because the lookup requires the pair. This distinction keeps the procedure repeatable: scan the branches, compare each against the table, and record only pairs whose two members both occur.

Positions and Co-Presence

When a pair is complete, note which positions hold each branch. For example, 子 in the year and 午 in the hour is a year–hour co-presence. The same pair with 子 in the year and 午 in the month is a year–month co-presence. Position labels describe where the branches sit; they do not change the detection rule. Repetition can also be described: if a branch appears more than once, say so plainly, but the pair still counts as one listed relationship between those two branch types.

Direction Versus Transformation

Each table entry carries an associated element direction, such as Water–Fire opposition for 子–午 or Earth pair for 丑–未. Treat this as a traditional label attached to the pair. It is not proof that either branch changed into another element, and it is not an established Transformation. A transformation would require separate conditions that this lookup does not supply. Do not invent tests, and do not upgrade a direction label into a confirmed change.

Finally, keep the raw chart intact. The engine retains every branch and its hidden stems in the five-element totals, so a detected clash does not erase or replace the branches involved. A clash is not automatically conflict, accident, divorce or loss. It is a co-presence finding, ready for careful reading rather than a verdict.

四 When the reading changes

Complete versus incomplete membership

A six clash is detected when both branches of one listed pair are present in the chart. The six pairs are 子–午, 丑–未, 寅–申, 卯–酉, 辰–戌 and 巳–亥. Membership is complete only when both characters appear somewhere among the four pillars. If you see 子 in the year branch and 午 in the hour branch, the pair is complete; if only 子 appears, no clash is detected. A concrete check is to scan the branch of each pillar in order and mark which of the twelve branches are present, then compare that set against the six pairs. The limited significance is this: detection means co-presence, nothing more. The associated direction, such as Water–Fire opposition for 子–午, is a traditional label for the pair, not proof that either element changed or that events followed. This point connects directly with How to Read a Bazi Chart: A Step-by-Step Guide for Beginners.

Repeated members

A branch can appear more than once. Two 子 branches and one 午 branch still contain the 子–午 pair, and the repetition is worth describing because it changes how often the pair occurs in the chart. A concrete check is to count each branch separately before matching pairs: list every branch, note duplicates, then ask whether the opposite member is also present. If 午 appears once and 子 appears twice, the pair is present, and you can say the 子 side is repeated. The limited significance is that repetition is a structural observation about the chart’s branch inventory. It does not multiply a verdict, and it does not turn a traditional opposition label into a stronger prediction.

Coexistence with another listed relation

One chart can contain more than one detected pair. For example, 子–午 and 辰–戌 may both be present if all four branches appear. A concrete check is to run the same membership test for every pair in the lookup, not just the first one you notice, and record each match separately. Coexistence means the chart contains both pairs at once; it does not mean the pairs interact, reinforce each other, or combine into a new relation. The limited significance is descriptive: you can report that two traditional oppositions are present, and you can note which pillars hold each branch. You should not claim that one pair cancels, transforms or explains the other.

Unknown hour or boundary uncertainty

If the hour is unknown, no Hour Pillar is invented, so the hour branch is unavailable for matching. A pair that would require the hour branch cannot be confirmed. A concrete check is to mark the hour branch as missing, then test only the year, month and day branches against the six pairs. Separately, year and month boundaries use China time, while day and hour boundaries use true solar time. If a birth time sits near a boundary, the day or hour pillar may be uncertain, and any pair involving that pillar is uncertain too. The limited significance is that uncertainty limits detection: you can state which pairs are confirmed from known pillars and which remain unresolved.

五 Worked chart examples

These teaching charts were screened by the site’s current calendar engine. They are not people or client stories. The relation matches and numeric tables are generated from frozen lookup rules and engine output; the prose only explains what is shown.

Chart A: Tracing the 子–午 Six Clash

Chart A has four pillars: 甲子 in the year, 丁卯 in the month, 甲寅 in the day, and 庚午 in the hour. Among the listed matches, one appears: a Six Clash between 子 and 午, labelled Water–Fire opposition.

To see how detection works, look only at the visible branches. The year branch is 子, and the hour branch is 午. Because both characters are present in the chart, the pair 子–午 is detected. Nothing more is required for the match to register: the two branches simply coexist in the four pillars.

The direction label, Water–Fire opposition, is a traditional association. 子 belongs to the Water group, while 午 belongs to the Fire group. This label describes the pair’s conventional element categories; it is not proof that either branch changed into another element, and it is not a verdict about the chart.

Location can also be described. Here the two branches sit in the year and hour positions, so they are separated by the month and day pillars rather than standing next to each other. The engine keeps each branch and its hidden stems in the raw totals. In Chart A, 子 carries hidden 癸, while 午 carries hidden 丁 and 己. These hidden stems remain part of the five-element totals: wood 4, fire 2.5, earth 0.8, metal 1, and water 1.

Those raw totals are not a strength verdict. They simply record what the calculator counts. A detected clash means co-presence, not automatically conflict, accident, divorce, or loss. Chart A therefore illustrates careful reading: identify the exact branches, note their positions, and treat the clash as a structural observation rather than a prediction.

Reading Chart B

Chart B has pillars 甲子, 庚午, 甲戌 and 戊辰. Its listed matches are two Six Clash pairs: 子–午, a Water–Fire opposition, and 辰–戌, an Earth pair. Detection here means only that both branches of each pair are present in the chart.

The 子 sits in the year branch and the 午 in the month branch, so the Water–Fire opposition spans two adjacent positions. The 辰 sits in the hour branch and the 戌 in the day branch, placing the Earth pair side by side. Neither pair repeats, and no branch appears twice, so each match rests on a single co-presence.

The five-element totals are wood 2.5, fire 1.3, earth 3.5, metal 1.5 and water 1.3. The engine keeps every branch and its hidden stems in these raw totals, so 子 still contributes its hidden 癸, 午 its hidden 丁 and 己, 戌 its hidden 戊, 辛 and 丁, and 辰 its hidden 戊, 乙 and 癸. The weighted Ten-God totals are Friend 1, Rob Wealth 0.5, Hurting Officer 1.3, Indirect Wealth 3, Direct Wealth 0.5, Seven Killings 1, Direct Officer 0.5 and Direct Resource 1.3. The visible Day Master, 甲, counts in the five-element totals but is excluded only from the weighted Ten-God totals.

Chart A, by contrast, lists one match: 子–午, the same Water–Fire opposition. Its totals differ — wood 4, fire 2.5, earth 0.8, metal 1, water 1 — and its Ten-God profile includes Friend 2, Rob Wealth 1, Eating God 0.5, Hurting Officer 2, Indirect Wealth 0.3, Direct Wealth 0.5, Seven Killings 1 and Direct Resource 1. Chart B therefore carries an additional Earth pair and a heavier earth total, while Chart A carries more wood.

A repeatable observation follows: read each listed pair as co-presence, note its two positions, then compare the raw element and weighted Ten-God totals before drawing any further conclusion.

六 Base-rate boundary

The full enumeration used by this site contains 518,400 valid Four Pillars combinations: 60 year pillars × 12 solar-month slots × 60 day pillars × 12 hour slots. This article covers a family containing several different pairs or frames, so one combined percentage would hide which exact condition was counted.

When a later analysis gives a frequency, read it as an equal-weight combination-space proportion, not a percentage of people or birth records. Define one precise pair or complete frame first, then count that condition without treating its presence as an event forecast.
