What is a 37-system synastry reading?

It cross-reads two birth charts through 37 systems at once — BaZi (Saju) compatibility, Zi Wei synastry, Western synastry aspects, Human Design connection channels, Vedic D9 and more. Enter both sets of birth data and every comparison is calculated together, so you can see where the traditions agree instead of relying on one.

Is it free? Do I need both birth times?

The synastry calculation is free and unlimited. Exact birth times sharpen the astrology and Human Design layers, but you still get a substantial reading without them. Written readings are separate one-off purchases: Essentials synastry NT$249, full synastry reading NT$899.

Does this work for friendships and family, not just couples?

Yes. You choose the relationship type before calculating — partner, friend, family or working relationship — and the reading is framed for that relationship rather than assuming romance.

Calculating is free. Essentials synastry is NT$249 and the full synastry reading is NT$899; the complete Relationship User Manual is NT$5,600. Every item is a one-off purchase — the English site sells no membership or subscription.

—

A chart gives you reference coordinates drawn from a large body of data. It is not an absolute, and it is not a basis for any decision. What this page is for is what comes after you can read those coordinates: finding the way of being together that actually suits you both.
