The I Ching Hexagram Meanings catalogue is a 64-entry reference lookup, not a casting or prediction tool. It does not toss coins, pick a random entry, calculate changing lines, or claim that any hexagram forecasts an event. Each of the 64 entries is a fixed pair of one King Wen number, one Unicode character from U+4DC0 through U+4DFF, and one official Unicode English name, so the tool's job is to locate and expose that identity. The first entry is ䷀ at U+4DC0, named HEXAGRAM FOR THE CREATIVE HEAVEN, and the last is ䷿ at U+4DFF, named HEXAGRAM FOR BEFORE COMPLETION. Search matches against a King Wen number, the visible hexagram character, a Unicode code point, an official Unicode name, or one of the eight trigram names. Separate filters narrow the list by the lower trigram (Lines 1–3) and the upper trigram (Lines 4–6). Because the catalogue is structural rather than divinatory, the result you see is a description of what a hexagram is, not a reading about what it means for you. The I Ching Hexagram Meanings tool is deliberately bounded by that line.
The Catalogue's Role: Reference, Not Reading
The catalogue is a fixed 64-row table of Yijing hexagram symbols. Every row is the same shape: a King Wen number from 1 through 64, the encoded character at one code point in the Unicode block U+4DC0 through U+4DFF, the official Unicode English name, and a six-line bottom-to-top string that decomposes into two trigrams. The catalogue does not invent or interpret; it displays what has been independently published by the Unicode NamesList and the Stanford Encyclopedia of Philosophy appendix.
Each entry is stored as a literal reference, so the production code cannot manufacture its own expected names. The catalogue is therefore a lookup, not a generator. When you open the tool, you see all 64 entries and Hexagram 1 selected by default; the search field, the lower trigram filter, and the upper trigram filter are the only inputs that change the visible list.
What the Tool Does Not Do
Several common I Ching actions are explicitly out of scope for this catalogue:
- It does not toss three coins or any other casting method.
- It does not pick a random hexagram.
- It does not calculate changing lines or a transformed hexagram.
- It does not reproduce a modern commercial translation.
- It does not attach an unsourced fortune to a result.
- It does not claim that any hexagram predicts a future event.
This boundary is part of the catalogue's contract. The page stops at reference facts and does not drift into interpretation. If you want a real read, the contract points you toward a separate mechanical three-coin tool rather than smuggling randomness into a reference list.
How to Look Up a Hexagram by Number, Character, or Trigram
- Type a King Wen number, hexagram character, Unicode code point, official Unicode English name, or trigram term into the search field. For example, "29" or "䷜" or "U+4DDC" or "Kan" or "Water".
- Optionally choose the lower trigram filter to limit results to hexagrams whose bottom three lines (Lines 1–3) form a specific trigram. The eight options are Qian, Dui, Li, Zhen, Xun, Kan, Gen, and Kun.
- Optionally choose the upper trigram filter to limit results to hexagrams whose top three lines (Lines 4–6) form a specific trigram from the same eight-name list.
- Click a matching entry in the list to inspect its exact Unicode identity: the King Wen number, the character, the code point, the official Unicode English name, and the lower-and-upper trigram decomposition.
- Click Reset catalogue to clear the search, clear both filters, restore all 64 entries, and return the selection to Hexagram 1.
The result count visibly updates as filters change, and an empty state explains how to recover when the two trigram filters have no intersection.
What the 64 Rows Contain
Each catalogue row is built from two independent public sources. The table below summarises which source fits which field.
| Source | What it provides | Scope |
|---|---|---|
| Unicode NamesList (U+4DC0–U+4DFF) | Exact code point and official Unicode English name for each hexagram | 64 characters |
| Stanford Encyclopedia of Philosophy appendix | Bottom-to-top yin/yang line codes for all 64 hexagrams | 64 row strings |
| Trigram split (after Line 3) | Lower and upper trigram identity for each hexagram | 64 splits |
| Catalogue (local) | One row combining the above with a short display name | 64 entries |
The first and last characters — ䷀ at U+4DC0 (HEXAGRAM FOR THE CREATIVE HEAVEN) and ䷿ at U+4DFF (HEXAGRAM FOR BEFORE COMPLETION) — bound the sequence. Every other row sits between them in King Wen order, with no row invented outside those two authorities.
The Eight Trigrams the Catalogue Uses
The eight displayed trigrams are Qian (Heaven), Dui (Lake), Li (Fire), Zhen (Thunder), Xun (Wind), Kan (Water), Gen (Mountain), and Kun (Earth). Each appears under both names and as a symbol beside the selected hexagram, so the structural decomposition is visible. The catalogue's two filters accept exactly these eight, and the bottom-to-top reading order is what makes "lower" and "upper" meaningful.
| Trigram | English name | Symbol |
|---|---|---|
| Qian | Heaven | ☰ |
| Dui | Lake | ☱ |
| Li | Fire | ☲ |
| Zhen | Thunder | ☳ |
| Xun | Wind | ☴ |
| Kan | Water | ☵ |
| Gen | Mountain | ☶ |
| Kun | Earth | ☷ |
Because the lower and upper halves each have eight options, there are 64 possible lower/upper combinations — exactly matching the 64 rows in the catalogue. The mapping is independent of any English title, because the 8-by-8 matrix is locked against the Stanford line codes, not inferred from a translation.
Reference vs. Reading: When to Use Which
The I Ching Hexagram Meanings tool is the right choice when you want to know what a hexagram is. The I Ching Reading tool is the right choice when you want a hexagram to be generated by a mechanical three-coin cast. The two tools deliberately do not overlap.
If you already have a King Wen number from somewhere else — a book, a class, a conversation — but you want to see the exact Unicode character, the official Unicode name, and the lower/upper trigram split, this catalogue is the right destination. If you want to perform a casting and see a primary and transformed hexagram with changing lines, the dedicated casting tool is the right destination. Mixing the two would either smuggle randomness into a reference table or strip structure away from a reading. The contract for this page even points readers in that direction: "Users seeking a mechanical three-coin cast can use the separate I Ching Reading tool."
Privacy and Local-Only Behaviour
The catalogue does not fetch, upload, or persist anything. Search and filtering operate over a fixed 64-row table in the browser. The component makes no fetch request, writes nothing to localStorage or sessionStorage, and uses no account. Closing or refreshing the page removes the transient filter state. Reset does the same job in one click: it clears the search field, clears both filters, restores all 64 entries, and selects Hexagram 1.
Keyboard access is built in: the native search and select controls support tab navigation, and long Unicode labels wrap rather than widen the page. The list and detail panel reflow into a single column on narrow screens, and a visible result count announces filtering changes so screen readers and sighted users see the same state.
Why Source-Backed Structure Matters
The 8-by-8 King Wen lookup matrix is independently locked against the Stanford Encyclopedia of Philosophy appendix, which publishes bottom-to-top yin/yang line codes for all eight trigrams and all 64 hexagrams. Splitting each six-line code after the third line gives the lower and upper trigrams. The Unicode NamesList supplies the encoding authority for the character, code point, and exact English name. The catalogue's correctness is measured against these two public sources, not against any divinatory interpretation.
That is what makes the tool useful even for a reader who does not believe in casting. You can use it to verify a hexagram's identity, to look up a Unicode character you cannot type, to find which trigram pair a given King Wen number resolves to, or to teach a class about the structure of the Yijing without ever asking the catalogue to predict anything. The verification list explicitly covers all 64 literal number, character, code-point, and Unicode-name identities; all 64 Stanford line codes; the complete 8-by-8 matrix; eight unique trigrams; representative lower and upper combinations; search; both filters; reset; privacy boundaries; and the absence of predictive claims. Correctness means reproducing the cited catalogue structure, not validating any interpretation.
