You need I Ching Hexagram Meanings when you want to look up one of the 64 hexagrams by its official Unicode identity, King Wen number, or lower and upper trigram structure, and not when you want the tool to generate a divination reading, predict an outcome, or cast new lines for you. The page is a browser-based 64-entry reference catalogue rather than a casting tool or a translation, built around the encoded characters U+4DC0 through U+4DFF. Each entry pairs exactly one King Wen number with one Unicode code point and one official English name, with ䷀ at U+4DC0 named HEXAGRAM FOR THE CREATIVE HEAVEN as the first entry and at U+4DFF named HEXAGRAM FOR BEFORE COMPLETION as the last. It also exposes the two trigrams that build the six-line figure, so you can confirm identity, decompose structure, or cross-check what you have in front of you. Deciding whether you actually need it is mostly a question of what is already in your hand: a hexagram you want to identify, or a question that still needs generating.
What the Catalogue Is and Is Not
I Ching Hexagram Meanings is a single-page reference catalogue for the 64 hexagrams in the received King Wen sequence. It maps each King Wen number from 1 through 64 to exactly one character in the Unicode block U+4DC0 through U+4DFF, with the official Unicode English name and code point displayed beside every entry. 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 can match a King Wen number, the hexagram character itself, a Unicode code point, the official Unicode English name, or a trigram term, and two optional filters let you narrow the results by the lower trigram on Lines 1 through 3 and the upper trigram on Lines 4 through 6.
It is intentionally not a casting tool. The catalogue does not toss coins, compute changing lines, predict an outcome, or supply a fortune. It does not embed any specific modern translation; it stops at structural identity and the official encoding label. If you need a mechanical three-coin cast with a primary hexagram and a transformed hexagram, you are describing a different tool, and the comparison section below explains how to tell when to switch.
Decision Checklist: Five Signs This Is the Right Tool
Run through these five conditions in order. If two or more apply, the catalogue is almost certainly what you need.
- You already have a hexagram in front of you (from a printed cast, a copied character, or a number you read somewhere) and want to identify it.
- You need to verify a Unicode code point or confirm the exact English name that Unicode publishes for the symbol you are looking at.
- You want to study the structural relationship between the lower and upper trigrams without generating any predictive text.
- You are reading a translation or commentary and want a quick reference for the identity and six-line structure of the hexagram being discussed.
- You do not want to submit a question, upload anything, or have your query logged, because the entire catalogue runs locally and writes no storage.
If your situation matches "I have a question and want the I Ching to answer it" rather than "I have a hexagram and want to identify it," keep reading the next section.
How to Look Up a Hexagram by Identity
- Open the I Ching Hexagram Meanings reference catalogue in your browser.
- Pick the field that matches what you have. Type a King Wen number from 1 to 64, paste the hexagram character, enter the code point such as U+4DC0, type a fragment of the official Unicode name, or enter one of the eight trigram names.
- If you want to narrow further, choose a lower trigram and an upper trigram from the two filter controls. Each filter pulls from the eight sourced trigrams: Qian or Heaven, Dui or Lake, Li or Fire, Zhen or Thunder, Xun or Wind, Kan or Water, Gen or Mountain, and Kun or Earth.
- Select a matching entry from the filtered list. The detail panel shows the short display name, the official Unicode name, the code point, the character, and the lower and upper trigram symbols side by side so you can confirm the structure directly.
- Use the Reset catalogue control to clear the search field, clear both filters, restore all 64 entries, and return the selection to Hexagram 1. Closing or refreshing the page also drops the transient filter state.
The result count is announced above the list, so when filters have no intersection you see an empty state that explains how to recover with Reset.
When a Different Tool Fits Better
The decision is sometimes the inverse of the checklist. You should reach for the separate I Ching Reading tool if you still need to cast six lines, calculate changing lines, or read a primary and transformed hexagram pair from a question you are asking right now. That tool runs the mechanical three-coin process locally, displays each line's coin math, and gives you both the source hexagram and the changed hexagram without the catalogue's identity lookup.
You should also step away from the catalogue entirely if what you actually need is a translation of the original line texts, the judgments, or the commentary. The 64-entry catalogue shows identity and structure, and deliberately omits any specific translator's wording. For reading the Book of Changes itself, the canonical Chinese Text Project edition is a common starting point, and the Stanford Encyclopedia of Philosophy appendix supplies the bottom-to-top yin and yang line codes that the catalogue's structure is independently locked against.
| You want to… | Reach for… | Why this fits |
|---|---|---|
| Identify a hexagram by number, character, code point, name, or trigram | I Ching Hexagram Meanings | Reference catalogue with exact Unicode identity and structural decomposition |
| Cast six lines from a question and see primary plus transformed hexagrams | I Ching Reading | Mechanical three-coin cast, changing lines, no predictive interpretation |
| Read the original Chinese text and line judgments | External source such as the Chinese Text Project | The catalogue deliberately omits any modern translation |
| Compare trigram structure across multiple hexagrams | I Ching Hexagram Meanings | Both trigram names and symbols shown on every selected entry |
| Verify a code point or official Unicode English name | I Ching Hexagram Meanings | Each entry pairs a code point with its Unicode-published name |
Reading the Lower and Upper Trigrams Correctly
Every hexagram is read from the bottom upward, and the bottom three lines form the lower trigram while the top three lines form the upper trigram. The catalogue mirrors this order: the lower trigram control filters Lines 1 through 3, and the upper trigram control filters Lines 4 through 6. The eight trigrams the filters expose are Qian or Heaven, Dui or Lake, Li or Fire, Zhen or Thunder, Xun or Wind, Kan or Water, Gen or Mountain, and Kun or Earth.
When the detail panel shows two trigram names and two trigram symbols side by side, you can confirm the hexagram by translating the pair back into a six-line figure in your head or on paper. The 8-by-8 King Wen matrix behind the catalogue is independently transcribed from the Stanford Encyclopedia of Philosophy appendix, so the lower and upper pair shown for every entry is the same pair that the appendix publishes rather than a reconstruction guessed from an English title. If you want the bottom-to-top yin and yang line codes themselves for any hexagram, the Stanford appendix is the authoritative structural source.
Verifying Identity Against External Sources
Two external references matter for identity, and both are easy to check side by side with what the catalogue shows.
- Unicode NamesList for the Yijing Hexagram Symbols block publishes the official English name and code point for every character in U+4DC0 through U+4DFF. The catalogue's official name and code point labels should match this list exactly for any hexagram you look up.
- The Stanford Encyclopedia of Philosophy Yijing appendix publishes the bottom-to-top six-line codes for all eight trigrams and all 64 hexagrams. Splitting each code after the third line produces the lower and upper trigrams that the catalogue should display for the same King Wen number.
Because the production code stores the full 64-row Unicode identity oracle as a literal fixture and maps King Wen numbers to the Stanford line codes independently, the two external references act as a check against each other. If the catalogue, Unicode NamesList, and the Stanford appendix all agree on the same lower and upper trigrams for a given King Wen number, the identity is verified three times over. If any of the three disagrees, the disagreement belongs to the source you trust least for that specific field, not to the catalogue silently reinterpreting the sequence.
The catalogue will not run a search if your input is empty, will not store any selection across page loads, and will not make a network request while you filter. Refreshing the browser or closing the tab drops every transient filter state, so a future session starts from all 64 entries and Hexagram 1 again. On narrow screens the list and detail panel reflow into a single column, the search and select controls stay keyboard-accessible, and long Unicode labels wrap rather than widening the page, which keeps the verification workflow readable on a phone as well as a desktop.
