What kind of person suits you

One birth date is all it takes. You can read this without knowing anyone's birthday — or without having anyone in mind yet.

Affinity works without the other person's birth date. It runs the compatibility engine in reverse — trying every value the missing side could hold — and finds which type fits you best on each of the same four axes: day-master relationship, elemental supply, day-branch relationship, and the spouse position. It shows each axis on its own instead of adding them into one score, because in a real person the day master and the elements don't move independently, so stitching together the top result on every axis would describe someone who couldn't actually exist. The same reasoning is used by Saju compatibility.

Gender
Traditional Saju reads the spouse position differently by gender. Leave it unset and that factor is dropped rather than guessed.

Time of birth

The spouse position (Jeongjae / Jeonggwan) can only be judged when both genders are known.

Nothing you enter is stored

Birth dates are used only while the result is being calculated and are never recorded. No account is needed. Nothing carried in a result link is sent to the server.

This is a traditional Saju reading offered for reference. It is not a scientific prediction or a verdict on any relationship.
