Both birth dates

Knowing the birth time makes the reading sharper, but it is not required.

Inyeon-Link builds each person's own eight characters, then scores two axes. Saju compatibility checks four things — what each day master is to the other in Ten Gods terms, whether the Five Elements supply what the other needs, whether either chart sits in the spouse position (Direct Wealth or Direct Officer), and whether the day branches combine or clash — while zodiac compatibility looks only at the year branch. The two axes are combined with a weighted average, and the reading works even without a birth time. Every weight and rule used here is published in the reasoning document below.
