Li Chun, not January 1
Birthdays before the Start of Spring use the previous Chinese solar year. The calculator resolves that date for each birth year instead of applying a fixed January cutoff.
Find your Ming Gua trigram, East or West group, and four supportive Eight Mansions directions from your birth date and traditional calculation convention.
Ming Gua belongs to Eight Mansions Feng Shui. It groups four compass directions as traditionally supportive, with a different order for momentum, health, relationships, and stability.

Classical arithmetic uses separate male and female formulas, including a century adjustment after 2000 and a conventional remap when the result reaches the center number 5.
Use Kua for a traditional spatial lens. Use BaZi when you want the Day Master, all Four Pillars, element balance, relationships, work themes, and personal timing from your exact birth moment.
A Kua number, also called Ming Gua, is used in the Eight Mansions school of Feng Shui. It assigns one of eight personal trigrams and four traditionally supportive compass directions from a birth year and a traditional male or female calculation convention.
The Feng Shui solar year changes at Li Chun, usually around February 4, rather than on January 1. A complete date lets the calculator move January and early-February births into the correct solar year.
For 2000 through 2099, the reduced last-two-digit birth-year value is subtracted from 9 under the traditional male convention or added to 6 under the traditional female convention, then reduced again. A result of 5 is conventionally reassigned to 2 or 8.
Classical Kua arithmetic uses different male and female conventions. The control names the formula directly so you can choose the convention you intend to use without treating it as a statement about identity.
Kua 1, 3, 4, and 9 form the East group. Kua 2, 6, 7, and 8 form the West group. Each number has its own ordering of Sheng Qi, Tian Yi, Yan Nian, and Fu Wei directions within that group.
No. Kua is a Feng Shui direction framework derived mainly from the solar birth year. BaZi calculates four stem-branch pillars from birth date, time, and place, then reads the Day Master, Five Elements, Ten Gods, and timing cycles.
Yes. The Kua number and four supportive directions are free with no account or email. The linked BaZi calculator also provides a free chart and introductory reading; five deeper chapters are an optional one-time $4.99 unlock.
