Feng Shui Kua Number

The Feng Shui Kua Number tool calculates your personal Kua (or Gua) number, a single digit from 1 to 9 derived from your birth year and gender that is central to the Eight Mansions (Ba Zhai) school of Feng Shui. Your Kua number sorts you into either the East group or the West group and reveals your four auspicious and four inauspicious compass directions.

The calculation uses your Chinese solar birth year — meaning a birthday before the early-February start of the year counts as the prior year — and applies the traditional formula that differs for males and females, then reduces the result to a number between 1 and 9 (with 5 reassigned by gender). Each Kua number maps to a trigram of the Bagua and to specific directions for prosperity, health, relationships, and personal growth.

People use their Kua number to orient beds, desks, and main doors toward favorable directions, to face their best direction while working or sleeping, and to choose homes and rooms that align with their group. East-group people thrive facing east, southeast, south, and north, while West-group people favor west, northwest, southwest, and northeast.

For accuracy, double-check that your birth year accounts for the Chinese New Year cutoff, since a January or early-February birthday may belong to the previous year. Combine the Kua number with the BaZi Calculator and Chinese Lunar Calendar for a fuller Chinese-metaphysics picture, and remember that direction recommendations describe the way you face, not merely the room you occupy.
