Not "are you compatible."
How you're compatible.

What this is

Both people's birth details. About a minute.

Any two people, not just a couple. A partner, someone you're dating, a friend, a parent or sibling, a business partner, a coworker you keep misreading — the reading works the same way for all of them, because it compares two charts rather than assuming what the two of you are.

We build a full Saju chart for each of you, then compare them on the three things that actually shape how two people run together:

• Do you fill each other's gaps? Everyone's chart is short of something. The question is whether the other person has it.
• How do your two Day Masters line up? That's the one sign in each chart that stands for the person. Some pairs lock together, some pull opposite. Both can work — they just work differently.
• Who feeds whom? Elements create and control each other. That pattern shows up as who gives, who leans, and who keeps whom honest.

You get a score and the two or three dynamics that matter. There is no such thing here as an incompatible pair — only pairs who know what they're working with and pairs who don't.
