How to use it
What this tool is useful for
Use the Shao Yong time or number formula to create a primary hexagram, changed hexagram, and moving line while keeping classical text separate from real evidence.
Divination
Mei Hua Yi Shu Casting Record
Apply the disclosed Shao Yong arithmetic to the current time or three numbers, preserve the primary hexagram, changed hexagram, moving line, and classical source text, then record evidence and counterevidence without forecasting an outcome.

How it works
This tool uses the details you enter on the page to produce a result. It is free to use, and your information is not sent to a third-party AI service.
Complete example
Worked example: three numbers through the formula
The written review question is kept beside the record but never enters the arithmetic. Only the three seeds below determine the trigrams and moving line.
Example details
- Casting mode
- Number-based
- Three seeds
- 8 · 16 · 24
- Review question
- Should this low-cost pilot continue for two weeks?
- Stored for later review; excluded from the formula.
Example result
- Upper and lower trigrams
- Kun above · Kun below
- Primary lookup
- The Receptive (坤) · binary 000000
- Moving line
- Line 6
- Changed lookup
- Splitting Apart (剥) · binary 100000
- A mechanical line flip, not a forecast of the pilot.
How to check it again
Calculate 8 mod 8 and 16 mod 8 for the two Kun trigrams, then use (8 + 16 + 24) mod 6 for moving line 6. Flip only the sixth line and compare both binary figures before reading any text.
What this example cannot prove
The hexagram pair cannot understand the question or choose an action. Contracts, measurements, safety, health, legal, and financial issues require their own evidence and qualified advice.
Use cases
Recommended
Study a casting formula
Inspect how time or three numbers become upper trigram, lower trigram, and moving line through modulo arithmetic.
Recommended
Preserve competing readings
Record at least two cultural interpretations with supporting evidence and counterevidence.
Replace contracts or evidence
Do not substitute a hexagram for legal, medical, financial, safety, or factual verification.
What the result is based on
Shao Yong time formula
Uses year-branch number, lunar month, lunar day, and hour-branch number to derive trigrams and moving line.
Number formula
Uses three values from 1 through 99 as transparent trigram and moving-line seeds.
Mechanical line change
Flips one binary line to form the changed hexagram without treating that operation as a future direction.
Classical source text
Displays Zhouyi Judgement and Image as historical material and labels the site paraphrase as a cultural gloss.
What you will see
Casting record
Preserves method, time or numbers, trigrams, and changing line.
Hexagram structure
Shows primary and changed hexagrams with key terms.
Source boundary
Separates classical text, site cultural gloss, and question text that never enters the formula.
Evidence record
Captures competing readings, support, counterevidence, a reversible step, and a stop condition.
What you can do next
Save the casting record
Keep the question, casting mode, time or numbers, and hexagram pair to prevent hindsight changes.
Write competing readings
Record at least two interpretations rather than selecting the most flattering one as fact.
Review evidence
Record facts first after 7-14 days, then compare support, counterevidence, and factors the hexagram never represented.
Question and result
Question text does not change the casting result, so the hexagram cannot understand context or prove a causal connection.
Privacy
The question stays on the current page and must not contain names, contact details, medical records, account data, or other identifiers.
High-risk decisions
Use professional advice and real evidence for consequential decisions.
A casting and lookup record
The page applies disclosed arithmetic to the current time or three numbers, producing an upper trigram, lower trigram, moving line, primary hexagram, and mechanically changed hexagram. It preserves the inputs, binary figures, Zhouyi Judgement, and Image text.
The written question remains beside the result for later review but never enters the formula. The generated hexagram therefore cannot understand the question or establish a causal connection to it.
Time-based formula
The current local clock time is converted to a lunar date. The common Shao Yong formula on this page uses the year-branch number, lunar month, lunar day, and hour-branch number.
- Upper seed equals year-branch number plus lunar month plus lunar day, reduced modulo 8.
- Lower seed adds the hour-branch number and is reduced modulo 8.
- The moving-line seed uses the same total and is reduced modulo 6.
- A zero remainder maps to trigram 8 or line 6 respectively.
Number-based formula
Number mode accepts three integers from 1 through 99. The first forms the upper trigram, the second forms the lower trigram, and the sum of all three forms the moving line. Every number and step remains visible so you can check the result again.
The random button only creates three random numbers. It adds no accuracy. Identical numbers produce an identical hexagram pair, but a repeated result does not validate the interpretation.
Classical text and cultural gloss
The Judgement and Image are displayed as historical Zhouyi source text. The site summary is labelled as a modern cultural paraphrase. Both may contain language about fortune, advance, retreat, or action, but neither is presented as a factual statement about the current question.
Keep at least two competing readings, supporting evidence, counterevidence, a reversible step, and a stop condition. Do not let the first appealing interpretation become the only story.
Privacy and high-risk limits
The question stays on the current page and is not saved after you refresh or close it. Do not enter names, contact details, medical records, account data, contract text, or other identifying information.
Contracts, health, law, finance, employment, relationship safety, and emergencies require real evidence and qualified advice. A hexagram cannot establish fortune, success probability, another person’s intent, or a future direction.
Preserve the casting record
Write one concrete question before casting, then save the selected method, local date and time or all three numbers, primary hexagram, changing line, changed hexagram, and the action you chose. Do not repeatedly cast until a preferred answer appears. Review the record after the event or within fourteen days and compare the symbolic reading with what actually happened. Contracts, safety, health, money, and legal facts still require direct evidence and qualified advice.
What is the difference between time-based and number-based casting?
Time mode uses the current moment, year-branch number, lunar month, lunar day, and hour-branch number. Number mode uses three chosen integers. The same numbers produce the same result, but that only shows the formula was applied consistently.
Will this match the older calculator?
The older page did not show every step. This version displays the calendar conversion, all three numbers, both trigrams, the moving line, and both hexagrams so you can check the result.
Does the written question affect the hexagram?
No. The question does not change the formula. It remains only on the current page, so the result cannot understand the question’s meaning or context.
Should I cast the same question again when I dislike the result?
No. Repeated casting encourages selection of the answer you already wanted. Save the first record, verify the real facts, choose a low-risk next step, and review later. Reformulate only when the situation or the question has materially changed.
