Kua Number Calculator
The kua number calculator turns a birth year and gender into one digit and an east or west group. The year cuts at Li Chun. The digit is not a luck score.

What you type in
Use the solar birth year and gender. The kua number calculator then checks Li Chun. A birthday on January 20 belongs to the previous Chinese year for this method. Gender changes the arithmetic, including how the digit 5 is reassigned: male 5 becomes 2, female 5 becomes 8.
You do not type a house facing here. Facing belongs to the building. Mixing them in one box is how two websites produce two ‘official’ numbers for the same person.
What you get back
The kua number calculator returns the digit, the group, and the four supportive directions used for bed and desk. Sheng Qi is the first choice for the pillow when the door is not in that line. If it is, use Tian Yi. The traditional names sit beside a plain-language line.
The free result is the full digit. A longer written reading can be saved to an account. The number itself is not locked.
| Field | Meaning |
|---|---|
| Digit | 1–9 after the 5 is reassigned |
| Group | East or west |
| Directions | Four supportive sides of the compass |
