Feng Shui Bedroom Report
Find your Gua and your four best directions, then check your bedroom against eight practical points. We show every step of the math and tell you which tips research backs.
How it works
Enter your birth date
Birth year is enough. Add month and day so we can apply the Lichun (Start of Spring) year boundary.
Get your Gua
A fixed formula gives your Gua and East or West group, with the arithmetic shown so you can check it.

Example · Male, born 1962
Kun Gua, West group
Headboard: point it northeast. That is his best direction, then northwest, west and southwest. (100 − 62) = 38, 38 ÷ 9 leaves remainder 2 → Kun.

Is this science?
No. These rules come from Ba Zhai (Eight Mansions), a traditional Chinese system. They have not been verified by modern science. Some checklist tips, like blocking light and noise, are backed by sleep research, and the report labels each tip so you can tell which is which.
Why do you ask for my birth month and day?
The system's year starts at Lichun, around February 4, not January 1. If you were born in January or early February, your Gua may follow the previous year. Without the date we calculate by year and say so.
Do I have to share my sex?
No. The traditional formula differs for men and women, so if you skip it the report shows both versions side by side.
Do you keep my data?
No. The report is calculated in your browser and nothing is sent to us. A nickname is optional and only used to greet you.
Will it tell me something bad is going to happen?
No. The system's category names are traditional labels, and the report says plainly that they are not predictions. When tradition and comfort disagree, the report sides with comfort.
