Cast a BaZi match

Enter both people’s birth date, time and place. The tool casts four pillars for each, compares the branch relations, the day masters and Ten Gods, the weighted element counts and the nayin years.

What kind of relationship is this?

Set this first: it decides which houses the reading looks at and how the five themes are ordered.

The type never enters the numbers: switching it leaves every aspect and placement identical. Now: Start from where the pull comes from and whether your rhythms match

What do you most want to see clearly?

Pick the closest one, or write it in your own words. Once the chart is cast, the reading answers it against both charts.

A

Person A

Synastry casts one natal chart per person, then reads the relationship between them. Order only decides which side is which.
