1. What is Kua Number?

The Kua number is a fundamental concept in Feng Shui that helps determine your auspicious and inauspicious directions based on your birth year and gender. It's used to optimize personal energy flow in your environment.

2. How Does the Calculator Work?

The calculator uses the WOFS formula:

Where:

• \( digit \) — Single digit obtained by summing all digits of birth year until reduced to one digit
• For males: Subtract digit from 10
• For females: Add 5 to digit, then reduce to single digit if needed

Example Calculation: For a male born in 1985: 1+9+8+5=23 → 2+3=5 → 10-5=5 (Kua number is 5)
