Three-coin divination is a traditional I Ching divination method that determines the yin-yang and static-dynamic nature of lines through combinations of heads and tails of three coins. The system simulates real coin tossing to ensure randomness and tradition.

A changed hexagram is a new hexagram formed after changing lines (old yin, old yang) transform. Interpretation requires combining primary and changed hexagrams:

• ✦No changing lines: Look at primary hexagram text
• ✦1-2 changing lines: Focus on changing line texts
• ✦3 changing lines: Primary and changed hexagrams are equally important
• ✦4-6 changing lines: Focus on changed hexagram

Traditional I Ching believes that the same question should not be repeatedly divined in a short time. Recommendations:

• ✦Wait at least one day between divinations
• ✦Re-divine when situation changes significantly
• ✦Take the first result as primary and contemplate its meaning deeply

Correctly understanding divination results requires:

• ✦Combining specific questions with current situations
• ✦Focusing on symbolic meaning rather than literal interpretation
• ✦Using it as a tool for thinking and reflection
• ✦Combining with rational analysis for decision-making

Interpretations on this site are generated by AI from the classical methods of the Yi — canon, principle, number, and divination — tailored to your specific question, and are for reference only, not a substitute for professional advice. The cast and hexagram calculation strictly follow the traditional three-coin method.

The six lines from bottom to top represent:

• ✦First line: Beginning stage of things
• ✦Second line: Development stage
• ✦Third line: Difficult stage
• ✦Fourth line: Advance-retreat stage
• ✦Fifth line: Success stage
• ✦Sixth line: Ending stage

Each line has its specific meaning and function.

These are hexagram relationships:

• ✦Nuclear hexagram: Composed of lines 2,3,4 as lower trigram and 3,4,5 as upper trigram
• ✦Opposite hexagram: Every line becomes its opposite
• ✦Inverse hexagram: The hexagram turned upside down

These relationships help us understand problems from different angles.

Sixty-four hexagrams come from combinations of eight trigrams: 8×8=64. Each hexagram consists of two three-line trigrams (eight trigrams), representing 64 basic states and change patterns of all things in the universe, covering all kinds of life situations.

Supreme Ultimate is a temporal philosophy system created by Shao Yong in the Northern Song Dynasty. It calculates hexagrams through mathematical relationships of years, months, days, and hours, believing that time itself contains the laws of universal change.

Calculation is based on complex mathematical relationships:

• ✦Assembly: 129,600 years per assembly
• ✦Operation: 10,800 years per operation
• ✦Generation: 360 years per generation
• ✦Year: 30 years per year
• ✦Month: Calculated by month

Corresponding hexagrams are derived through combinations of these cycles.

Enter the BCE year number in the year input box, then check the 'BCE' option. The system will automatically adjust the calculation method to accommodate BCE time calculations.
