## Zodiac Birth Year

The astrological year begins at Lichun (315° solar longitude), usually around February 4.
If the birthdate is before Lichun, use the previous Gregorian year to calculate the Zodiac year.

Zodiac Sign = Year Branch = (Birth Year − 4) mod 12 + 1
Year Stem = (Birth Year − 4) mod 10 + 1

Example: 1984
(1984−4) mod 10 + 1 = 1 → Yang-Wood
(1984−4) mod 12 + 1 = 1 → Rat
Zodiac of Birth Year 1984 = Yang-Wood Rat

## Zodiac Sign of the Prediction Year

Use the same formula:
Year Stem = (Year − 4) mod 10 + 1
Year Branch = (Year − 4) mod 12 + 1

Example: 2026
(2026−4) mod 10 + 1 = 3 → Yang-Fire
(2026−4) mod 12 + 1 = 7 → Horse
Zodiac of Prediction Year 2026 = Yang-Fire Horse

## Five Element Relationships
### Mother-to-Child (Producing) Relationship:

Metal → Water
Water → Wood
Wood → Fire
Fire → Earth
Earth → Metal

➡️ The Mother Element gives protection, support, education, resources, and advice.
➡️ The Child Element represents expression, behavior, performance, talent, relaxation, and reputation.

### Overcoming (Controlling) Relationship:

Metal over Wood
Wood over Earth
Earth over Water
Water over Fire
Fire over Metal

➡️ The Controlling Element dominates the other.
➡️ This implies money, income, wealth, and luxury.
➡️ For males, the element being controlled represents females (e.g., girlfriend, wife).

### Challenging (Surrendering) Relationship:

Wood yields to Metal
Earth yields to Wood
Water yields to Earth
Fire yields to Water
Metal yields to Fire

➡️ The surrendering element faces pressure from the controlling one.
➡️ This implies career pressure, jobs, legal issues, or authority.
➡️ For females, the controlling element represents males (e.g., boyfriend, husband).

### Friend and Peer Relationship:

Metal ↔ Metal
Water ↔ Water
Wood ↔ Wood
Fire ↔ Fire
Earth ↔ Earth

➡️ Same-type elements indicate friendship, peers, coworkers, social life, and expenses.


## How to Make Predictions

1. Find the Main Element of the birth year.
   Example: 1984 = Yang-Wood Rat
   The Rat’s Main Element is Water → Master Element = Yang-Water

2. Find the Element of the prediction year’s stem and zodiac.
   Example: 2026 = Yang-Fire Horse
   The Horse’s Main Element is Fire

3. Analyze the relationships:

   * Yang-Water vs. Yang-Fire of 2026 (Master Element vs. Year Stem)
   * Yang-Water overcomes Fire → relates to money and financial gains
   * Yang-Water vs. Yin-Fire of 2026 (Master Element vs. Horse Zodiac)
   * Again, Water overcomes Fire → more focus on wealth or income

✅ Conclusion: Both the Stem and Zodiac of 2026 relate to financial themes for this person.
