What is Zi Wei synastry?

Zi Wei synastry is the traditional practice of placing two Zi Wei Dou Shu charts side by side to read how their stars interact. By comparing each person's twelve palaces — Life, Spouse, Fortune and others — together with the pull of the major stars and the Four Transformations, it reveals the chemistry between two people in companionship, romance, and collaboration. xuanzhang computes both charts deterministically with the iztro engine, then has AI interpret the palace interplay — the casting is exact; AI only reads it.

Three lenses

Friendship

Reads your dynamic through the Fortune and Travel palaces — who sets the mood, who steadies things, and how you fare as long-term friends.

Love

Centers on the interplay of the Spouse and Life palaces to weigh attraction, friction, and lasting rapport — fleeting spark or long-term fit.

Career

Cross-reads the Career and Wealth palaces for division of labor, complementarity, and potential conflict when you work together.

About Zi Wei synastry

AI two-chart comparison — friendship, love, and career lenses

Is Zi Wei synastry accurate?

The chart casting is fully deterministic — for the same birth time, the iztro engine always produces the identical twelve palaces and stars, with no variance. AI only interprets the interaction between palaces; it does not predict the future but helps you understand each person's character and relational tendencies.

Do I need the other person's birth time?

Yes. An accurate comparison needs both people's birth date and time (the hour sets the Life palace). If the exact hour is unknown you can use an approximate window, but precision drops.

How is this different from BaZi marriage compatibility?

Zi Wei synastry centers on stars and the interplay of the twelve palaces, reading overall chemistry — suited to friends, partners, and colleagues. BaZi marriage compatibility centers on Five-Element interactions and useful-god complementarity, traditionally focused on marriage. The lenses differ and complement each other.

Can we compare if we're not dating or married?

Yes. Zi Wei synastry isn't limited to romance — the friendship lens suits close friends, and the career lens suits business partners and coworkers. Any two people can be compared.

How much does it cost?

Zi Wei synastry is a one-time US$4.99 (HK$28), permanently unlocking that comparison report — friendship, love, and career analysis plus a 9:16 shareable card for Instagram or Xiaohongshu.

Can I share the result?

Yes. Each comparison generates a personal link and a 9:16 card image to share. The link page never exposes your exact birth date and is not indexed by search engines.
