Jie Sha (劫煞): the Robbery Star, Its Lookup and What It Does Not Predict

一 What it is

What Jie Sha Means

Jie Sha (劫煞), the Robbery Star, is a symbolic marker in a Bazi chart. Its traditional theme is outside interruption and sudden taking away: something arrives from beyond your own effort and removes what seemed settled. Think of a quiet afternoon when a courier knocks with a parcel you never ordered, and while you sign for it, the pot on the stove boils dry. Nothing criminal occurred, yet the moment was claimed by an outside event. For the underlying framework, see How to Read a Bazi Chart: A Step-by-Step Guide for Beginners.

The historical name is not a literal event forecast. It does not say theft, accidents, crime, financial loss or victimhood will happen; such claims do not follow from the lookup rule. The star only flags a branch position where that theme is traditionally noted. It also differs from Rob Wealth Jie Cai, a Ten God derived from Day Master polarity, so the two should never be conflated. Year and day branches each produce targets independently; merge those targets, then scan all four branch positions. A same-basis self-hit never occurs, though a cross-reference hit can. The birth time cannot be inferred from star counts, and counts are not strength scores.

二 Where to find it in your chart

Where to Find the Robbery Star in the Calculator

Open the homepage calculator, enter the birth place and date, then the birth time if you know it. If the hour is unknown, select I don't know the hour; do not invent a time, because the hour pillar and its branch would be fabricated. Submit the form and read the Four Pillars chart that appears.

Look at the lower row of each pillar: those are the four branches. The Robbery Star (劫煞, Jie Sha) is a branch star, so it can only land on a branch, never on a stem. Its lookup uses the year branch or the day branch as an independent basis. Find which group your basis branch belongs to: 子辰申 targets 巳; 丑巳酉 targets 寅; 寅午戌 targets 亥; 卯未亥 targets 申. Each basis produces its own target, and the two targets merge before you scan all four branch positions. A basis never hits itself, though the other basis can still land there.

Below the pillars, open Stars in your chart. The exact English name is Robbery Star, shown with 劫煞. Each hit lists its pillar position and matching branch, so you can verify the positions directly. The traditional theme is outside interruption and sudden taking away; it is symbolic, not a prediction of theft, accidents, crime, loss, or victimhood. Keep it distinct from Rob Wealth (劫财), a Ten God from Day Master polarity.

三 How to read it

How the Robbery Star Lookup Works

Start with the Jie Sha 劫煞, the Robbery Star. Its rule is year-and-day: the Year branch and the Day branch each act as an independent basis. The lookup maps a basis branch to one target branch. If the Year branch belongs to 子辰申, the target is 巳; 丑巳酉 gives 寅; 寅午戌 gives 亥; 卯未亥 gives 申. The Day branch runs the same map separately. A basis never hits itself, but a target produced by one basis can land on the other basis branch, so cross-reference hits are possible. The method is easier to compare with Jiang Xing (将星): the General Star and How Its Position Is Calculated.

Keep basis and hit distinct. The basis is the branch you read from; the hit is any of the four branch positions — Year, Month, Day, Hour — that carries the target. When both bases produce targets, merge those targets and scan all four branches once. In the first sample chart, Year 未 yields target 申, which lands on the Day branch, while Day 申 yields target 巳, which lands on the Hour branch. The second chart shows convergence: Year 申 and Day 子 both yield 巳, so the Hour branch is recorded once after the duplicate target is merged.

The Day Master is Jia 甲 here, and it governs Ten Gods interpretation: Jia sees Jia as Friend, Yi as Rob Wealth, Geng as Seven Killings, and so on. That polarity mapping is separate from the star lookup. The Robbery Star is found from branch triads, not from the Day Master, so a chart can show Jie Sha without any particular Ten God pattern. Do not confuse Jie Sha with Rob Wealth Jie Cai 劫财, which is a Ten God derived from Day Master polarity.

Weighted ten-god sums count visible non-day stems at 1.0 plus hidden stems at positional weights 1.0, 0.5, and 0.3; only the visible day stem is excluded, while hidden Jia remains Friend. These counts are not strength scores, and no star changes totals or diagnoses a person. Treat the reading as traditional symbolism: outside interruption and sudden taking away, not a forecast of theft, accidents, crime, loss, or victimhood. The birth time cannot be inferred from star counts, and the lookup alone cannot establish one.

四 When it plays out differently

When the target branch is absent

Run the lookup first, then scan. Take the year branch and the day branch separately, map each through the Jie Sha table, and check whether the resulting target appears among the four branches. In the first supplied chart, year Wei 未 belongs to the 卯未亥 group and points to Shen 申, present at the day; day Shen 申 belongs to the 子辰申 group and points to Si 巳, present at the hour. Both bases land. For a genuine no-hit case, neither derived target may occur in any of the four branches. Removing Si from the other positions would not erase Chart A's Day Shen hit, because Shen is already fixed in the Day column. Absence is a complete result, not a hidden or delayed hit. It means the configuration does not carry this branch marker, so read the other stars that do appear rather than forcing an interpretation onto a missing target. This point connects directly with Wang Shen (亡神): the Loss Star and How to Read Its Position in Bazi.

Repeated target slots

A target can be hit more than once, and the count matters for description, not for weight. In the second supplied chart, year Shen 申 points to Si 巳 and day Zi 子 also points to Si 巳; the hour branch Si 巳 is reached by two independent bases. The trace records two rows, one from the year and one from the day, both landing on the hour. Check this by listing each basis-target pair separately before totaling anything. Those two lookup routes produce one marked Hour slot after merging, not two hits or a doubled marker. They do not create a stronger or more dangerous version of the star. Here the two bases belong to the same triad, which is why they select the same target. Multiple marked slots would require that target to appear in multiple pillar positions.

Jie Sha beside Rob Wealth

Keep the branch star distinct from the Ten God that sounds similar. Rob Wealth (劫财, Jie Cai) is derived from the Day Master's polarity: with Jia 甲 as Day Master, Yi 乙 is Rob Wealth. Jie Sha 劫煞 is a branch lookup, produced by the year or day branch and its target table. In the first chart, Rob Wealth appears only as a hidden stem at 0.3, while Jie Sha appears as two branch hits. In the second chart, Rob Wealth does not appear in the weighted sums at all, yet Jie Sha still hits the hour. Compare the two columns directly: one is a stem-based Ten God total, the other a positional branch marker. They can coincide, but neither creates, cancels, or explains the other.

Position changes the reading

Where the target lands changes what you can say about it. A hit at the year or month branch sits in the earlier or outer positions; a hit at the day or hour branch sits closer to the Day Master or in the later position. In the first chart, Jie Sha reaches the day and the hour. In the second, it reaches only the hour, even though two bases point there. Check the slot label in the trace before interpreting: the same target branch carries a different positional role depending on whether it appears at year, month, day, or hour. This is a distinction of location, not of severity.

Cross-reference with a related star

Read Jie Sha alongside the other stars already present rather than alone. In the first chart, the hour branch Si 巳 carries both Jie Sha and the Travelling Horse (驿马), while the day branch Shen 申 carries Jie Sha, the Red Phoenix (红鸾), and the Solitary Star (孤辰). In the second chart, the hour branch Si 巳 carries Jie Sha and the Academic Star (文昌贵人). These co-occurrences are observable from the supplied star lists. They let you describe which markers share a branch; they do not license a combined prediction, and they do not turn a symbolic pattern into advice about health, money, or relationships.

五 Worked chart examples

These teaching examples were screened from the calendar engine. They do not describe clients or claim life events. Tables and weights are generated by code using the calculator’s rules.

Chart A: 己未 · 丁丑 · 甲申 · 己巳

Chart A uses Jia 甲 as its Day Master, seated on the day branch 申 Shen. The Robbery Star (劫煞, Jie Sha) here follows the year-and-day rule, so two bases run independently and neither is treated as a second basis for the other. The year branch 未 Wei belongs to the 卯未亥 triad, whose target is 申 Shen; that target lands on the day branch itself. The day branch 申 Shen belongs to the 子辰申 triad, whose target is 巳 Si; that target lands on the hour branch. The two bases therefore merge to the same star, and the scan across all four branches returns hits at Day 申 and Hour 巳. No same-basis self-hit occurs, but the cross-reference hit is present.

Reading the stems under Jia: the visible non-day stems are 己 Ji (year), 丁 Ding (month) and 己 Ji (hour), while the visible day stem 甲 Jia is excluded from the weighted sums. Hidden stems are 己丁乙 in 未, 己癸辛 in 丑, 庚壬戊 in 申, and 丙庚戊 in 巳. Three concrete relationships follow. First, the two visible 己 Ji are Direct Wealth, and hidden 己 also appears in 未 and 丑; those two hidden contributions and two visible Ji stems account for Direct Wealth 4.0. Second, hidden 庚 Geng in 申 and 巳 supplies Seven Killings, the officer that controls Jia, and it sits in the same branches that carry the Jie Sha hits. Third, hidden 壬 Ren in 申 is Indirect Resource, feeding Jia while sitting beside that same 庚 Geng, so support and control share one branch.

The distinctive configuration is that both Jie Sha bases converge on branches already carrying other stars: 申 holds the Red Phoenix and Solitary Star, while 巳 holds the Academic Star and Travelling Horse. The star marks a symbolic theme of sudden outside interruption; it does not predict theft, accidents, crime, financial loss or victimhood, and the birth time cannot be inferred from these counts.

Chart B: Same Star, Different Basis

Chart B is 庚申 year, 戊寅 month, 甲子 day, 己巳 hour. The Day Master is still 甲 Jia, so every stem-to-god mapping from Chart A carries over unchanged. What changes is the branch material the lookup runs on, and that shift is worth tracing step by step.

The Robbery Star 劫煞 uses a year-and-day rule: each basis branch maps to one target, the targets merge, then all four branches are scanned. Here the year branch 申 Shen belongs to the 子辰申 group and targets 巳. The day branch 子 Zi belongs to the same group and also targets 巳. Both bases converge on one target, and 巳 sits in the hour. The trace is therefore year 申 → 巳 (hour) and day 子 → 巳 (hour): two bases, one hit, not two separate stars.

Compare Chart A, where year 未 targeted 申 and day 申 targeted 巳, producing hits at day and hour. Chart B collapses that to a single hour hit because its two bases share a triad. The star's position moved; its meaning did not. 劫煞 still denotes outside interruption and sudden taking away, and it remains a branch star, never a Ten God. Do not confuse it with 劫财 Jie Cai, the Rob Wealth god read from Day Master polarity.

The weighted sums also differ. Chart B shows Seven Killings 2.5, Indirect Wealth 1.9, Eating God 1.5, Friend 1.0, Direct Resource 1.0, Direct Wealth 1.0, Indirect Resource 0.5. Chart A instead led with Direct Wealth 4 and carried Hurting Officer 1.5 plus Rob Wealth 0.3. These counts are not strength scores, and the star adds nothing to them. The visible non-day stems are counted at 1.0, while hidden stems use positional weights of 1.0, 0.5, and 0.3; only the visible day stem is excluded, and hidden Jia still counts as Friend.

One limitation: the birth time cannot be inferred from star counts. Read the hour pillar directly.

六 How common is this configuration?

Across all 518,400 possible Four Pillars combinations in the enumeration used here, 劫煞 appears in 38.4838% (199,500 combinations). A chart is counted once if it contains at least one match.

This is an equal-weight combination-space proportion, not a percentage of people and not the frequency in a birth registry. We enumerate 60 year pillars, 12 solar-month slots, 60 day pillars and 12 hour slots, with the paired stem rules respected. Calendar duration, birth timing and unknown hours are not population-weighted.

The lookup checks both the year and day branch, merges their target branches, and scans all four positions, including possible cross-reference matches between Year and Day. A basis cannot target itself for this star. This convention matters: a different lookup convention can produce a different rate. None of these labels establishes a life outcome.
