Three steps, under a minute
Two people go in, one clear rate comes out, and a plain explanation follows it.

One rate, built from two systems
BaZi Four Pillars
Each partner’s birth date and birth time, when known, become a set of four pillars. Both sets sit side by side, so the rate reads two people at once.
Gua numbers
Each partner gets a Gua number from their birth date and the sex the Gua formula needs. Both numbers are fused with the pillars into one exact rate.
The years ahead
Past today’s rate, the explanation shows which years ahead will carry the relationship and which will test it, so a hard year is named before you meet it.
Sample result
Two example people
Both charts keep a similar pace, and the rate sits well above the middle. The years ahead mostly carry the relationship, with year four asking for patience. The explanation names each year and says why it carries or tests.
