What is timing in Liu Yao?
Timing is the moment when an event already indicated by the hexagram actually appears. In other words, after judging fortune and misfortune, the reader must answer the next question: when will it happen. Zeng Shan Buo Yi by Da He Lao Ren devotes a whole chapter, chapter 26D titled "General Commentary on the Various Categories of Timing", to gathering the rules for fixing time into one place. The approach is not guesswork by feeling, but tying the moment to the specific state of the Useful God line in the hexagram.
Two different matters need to be distinguished. One is qualitative: is this matter good or bad, successful or failed. Two is temporal: if successful, around when; if failed, around when. Timing belongs to the second. In some hexagrams the querent does not need to know good or bad but only when, for instance asking "when will I move house", "when will the paperwork be done". Then the analysis focuses entirely on timing, and fortune or misfortune is only background.
The five core groups of rules
According to Zeng Shan Buo Yi chapter 26D, the timing rules can be grouped into five main sets, each corresponding to a state of the Useful God line.
Static lines await the day of rule or the day of clash
A static line is one that does not move in the hexagram. For a static line, the rule is to await the day whose earthly branch matches the branch of the line, called the day of rule, or to await the day whose branch clashes with the line, called the day of clash. The day of rule is considered the most standard timing point for a static line, because then the line receives the exact qi of itself. The day of clash is a secondary point, used when a static line needs an external push to reveal itself.
The principle "A person in the Tomb does not emerge without a clash" explains why many static lines stay hidden until a day of clash arrives. Divination texts also mention the pair of principles "Clash the Void and it rises, break the Tomb and it opens", meaning a clash at the Void rouses it, and breaking the Tomb opens it.
Moving lines await the day of combination or the day of rule
A moving line is one that has already moved, meaning a signal of change has appeared in the hexagram. For a moving line, the rule is to await the day of combination or the day of rule. The day of combination is a day whose branch forms a six-combination with the branch of the line, for example a Zi line awaits a Chou day. The day of rule is a day matching the branch of the line, for example a Zi line awaits a Zi day. These two points do not exclude each other, and depending on the situation the reader chooses which comes first.
Some people argue that the I Ching is a divination text. 16 (Tian Huo Tong Ren) gives an example of timing in this direction: when the Original God generates the World and has moved but is then countered by a returning clash, one may await the day that clashes the line causing the returning clash, or await the day when the Original God is in rule so it no longer fears the returning clash. This applies the day of rule and the day of clash as two supporting points.
Lines in excessive vigor await the day of the tomb or the day of clash
A line in excessive vigor is one that has reached the peak of its vigor. By the law of rise and decline, excessive vigor must at some point decline, and that point is usually tied to the Tomb or to a clash. The Tomb is a state of being locked in a storehouse, making the line temporarily ineffective. A clash is a strong blow that makes the line reveal itself fully and then exhaust its momentum. This rule reminds the reader that a very strong line does not mean the matter will happen at once, but that one must await the moment when the vigor is blocked, and only then will the matter appear at the right time.
Lines void in the cycle await leaving the cycle or a clash
Void in the cycle is the state in which each ten-day cycle has two earthly branches not paired with a heavenly stem. A line falling on those two branches is considered Void, meaning temporarily without effect. The rule is to await leaving the cycle, that is the day when that branch is paired again with a heavenly stem, or to await the day that clashes the Void. Both points restore the Void line to activity. In Zeng Shan Buo Yi, the author stresses that a World line in Void in the cycle is one of the notable signs when judging both fortune and timing.
Lines under month breach await the next month or a combination
Month breach is the state in which a line is clashed and broken by the month's branch. The rule is to await the next month, meaning when another month comes the line is no longer clashed by the old month's branch, or to await a day of combination to mend it. Zeng Shan Buo Yi places Month Breach in a separate chapter, chapter 27, right after chapter 26, showing this concept is valued on par with Void in the Cycle and Birth, Vigor, Tomb, and Extinction.
Table of Useful God states and commonly assigned timing
The table below summarizes the rules above according to the state of the Useful God line. The source column names the chapter of Zeng Shan Buo Yi to which each rule belongs.
| Useful God state | Commonly assigned timing | Principle | Source |
|---|---|---|---|
| Static line | Day of rule or day of clash | A static line needs its exact qi or a push to emerge | Zeng Shan Buo Yi chapter 26D |
| Moving line | Day of combination or day of rule | A line that has moved awaits a closing point or its own qi | Zeng Shan Buo Yi chapter 26D |
| Line in excessive vigor | Day of the tomb or day of clash | Extreme vigor must decline, await the moment it is blocked | Zeng Shan Buo Yi chapter 26D |
| Line void in the cycle | Leaving the cycle or day of clash | The Void needs to be filled or awakened | Zeng Shan Buo Yi chapters 26a and 26D |
| Line under month breach | Next month or day of combination | Escape the old month's clash or be recombined | Zeng Shan Buo Yi chapter 27 |
| Line entering the Tomb | Day of clash with the Tomb or day of breaking the Tomb | A person in the Tomb does not emerge without a clash | Zeng Shan Buo Yi chapter 26b |
Example hexagram cast with LapQueLucHao and timing by each rule
To illustrate, below is a hypothetical hexagram cast with the LapQueLucHao tool. This hexagram is not copied from any source, but only used to show how the timing rules are applied.
Suppose the querent casts on a Yi Wei day, in a Bing Shen month, asking about a job application. The hexagram obtained is Shui Di Bi, with the third and fifth lines moving. After assigning the stems, the hexagram has the following structure:
- Sixth line: Wife Wealth Zi Water, static
- Fifth line: Brother Xu Earth, moving
- Fourth line: Offspring Shen Metal, static
- Third line: Officer Ghost Mao Wood, moving
- Second line: Parent Si Fire, static
- First line: Brother Wei Earth, static, holding the World
Suppose the Useful God is Officer Ghost Mao Wood on the third line, currently moving. This line is moving so by the rule "a moving line awaits the day of combination or the day of rule". The branch Mao combines with Xu, so a Xu day is one timing point. The branch Mao matches a Mao day, so a Mao day is the second point. In addition, Officer Ghost Mao Wood may be affected by the Brother Xu Earth line moving on the fifth line, since Xu combines with Mao, so the Xu day point is further reinforced.
If one applies the sexagenary calendar of the calculation core to convert to solar dates, instead of counting by hand, then after the casting day Yi Wei, the nearest Mao and Xu days can be determined specifically. For instance if the casting day Yi Wei corresponds to a day in August, then the next Mao day falls about four days later, and the Xu day about eleven days later. This conversion helps the reader avoid counting stems and branches by hand, and prevents confusion when a month has repeated branches.
In the same hexagram, if the World line is Brother Wei Earth and static, then by the rule "a static line awaits the day of rule or the day of clash", the timing for the World line is a Wei day or a Chou day. If the Offspring Shen Metal line is static but in excessive vigor because the Shen month supports it, then by the rule "excessive vigor awaits the tomb or a clash", the timing may be a Chou day (the tomb of Metal) or a Yin day (clashing with Shen). Thus, in one hexagram alone there are at least three different groups of timing points, depending on which line is chosen as the focus.
Why can one hexagram yield several timing points?
The timing rules do not exclude each other, but often overlap. A line may be static and in excessive vigor, void in the cycle, and under month breach all at once. Then each rule gives a different point, and the reader must weigh which is more reliable based on the specific situation. Zeng Shan Buo Yi chapter 26D mentions that one must base the judgment on the actual circumstances of the matter, not distinguishing great from small affairs, long-lasting from temporary things, and predicting uniformly will surely produce distorted results.
Some people argue that the I Ching is a divination text. 16 (Tian Huo Tong Ren) also stresses the same: distant matters correspond to years and months, near matters to days and hours. This is not a fixed law, but the reader's judgment based on how near the question is. Asking about a matter within the day, the timing should be counted in hours. Asking about a matter within the month, the timing should be counted in days. Asking about a matter within the year, the timing should be counted in months. Asking about a long-term matter of many years, the timing should be counted in years.
Where schools and books do not agree
One point to state clearly is that choosing the time unit, that is choosing day, month, or year, has no fixed law in the books. Zeng Shan Buo Yi chapter 26D only says one must base it on actual circumstances, and gives no hard conversion table. Some people argue that the I Ching is a divination text. 16 (Tian Huo Tong Ren) also only says distant matters correspond to years and months, near matters to days and hours, without defining a specific threshold. This is the reader's judgment, and different masters may choose different units for the same hexagram.
Another point of disagreement is the priority order among the rules. Some schools emphasize the day of rule, holding that a static line must await the exact day of rule to respond, while the day of clash is only a secondary point. Other schools hold that the day of clash is more important, because a clash makes the line move and reveal itself. Zeng Shan Buo Yi chapter 26D presents both points without ranking them clearly, leaving the reader to weigh them.
On void in the cycle, there are also two interpretations. One is that awaiting leaving the cycle, the line automatically becomes active again, without needing a clash. The other is that one must await the day that clashes the Void for the line to truly start. Zeng Shan Buo Yi chapters 26a and 26D both mention void in the cycle, but do not assert definitively which is more correct.
On month breach, Zeng Shan Buo Yi chapter 27 places it in a separate chapter and is somewhat strict, holding that a line under month breach is usually hard to use. But later books sometimes relax this, holding that if the line is generated by the day god or by a moving line it can still be saved, and the timing is when it is recombined. This is where books do not fully agree.
Limits of timing in Liu Yao
Timing is the hardest part of Liu Yao to verify. Fortune and misfortune can be checked against the final outcome, while timing must be checked against a moment, and a moment is easily stretched or shrunk depending on the viewpoint. A matter occurring within three months can be seen as corresponding to the month point, or to the day point if the reader chooses the nearest day. Therefore, timing should not be used to set dates for important matters such as signing a major contract, surgery, or an investment decision. Important matters should rely on actual information and expert opinion, and timing should only be taken as a directional reference.
It should also be noted that the timing rules above are presented in Zeng Shan Buo Yi chapter 26D, an ancient work, and do not mean they are correct in every case. The reader should record the hexagram and the actual outcome to check against, rather than applying them mechanically. This approach both preserves the spirit of the book and avoids turning timing into a hard promise that reality cannot meet.
Summary of commonly used timing points
One can gather a quick reference table of commonly used timing points, for convenience when judging a hexagram.
| Situation | First point | Second point | Note |
|---|---|---|---|
| Static line | Day of rule | Day of clash | Day of rule is considered more standard |
| Moving line | Day of combination | Day of rule | Choose order by situation |
| Line in excessive vigor | Day of the tomb | Day of clash | Await when vigor is blocked |
| Line void in the cycle | Leaving the cycle | Day of clash | Two interpretations |
| Line under month breach | Next month | Day of combination | Later books sometimes relax |
| Line entering the Tomb | Day of clash with the Tomb | Day of breaking the Tomb | A person in the Tomb does not emerge without a clash |
This table does not replace a careful reading of Zeng Shan Buo Yi chapter 26D and related chapters, but is only a quick reference tool. When judging a specific hexagram, one must still examine the whole structure of the hexagram, the relations among the lines, the influence of the day god and month branch, and only then decide which timing point is more reliable.
