Birthday compatibility
Zodiac animals compare only birth years. Korean Saju compatibility compares two full birth charts: how your hearts connect, how you are up close, what each of you brings the other, and which months are good for you both.
What we compare
- Your day masters
The top character of each day pillar stands for each of you. Whether one feeds, guides or mirrors the other shows how your hearts connect. Five special pairs, called stem harmonies, add a strong pull.
- The spouse seat
The lower character of your day pillar shows how you are with the person closest to you. Natural pairs fit easily, and opposites clash but can teach each other a lot.
- What you give each other
Each chart has an element it needs most (yongsin). If your partner's chart holds it, being together tends to feel steadying.
- Your year together
For each month of the year, we show when you both have energy and when one of you may need extra support.
The result is a level from 1 to 5, using the same rules as our Korean site. Your zodiac animal match is included as a light extra.
Compatibility in Saju is a tradition for reflection, not a verdict on any relationship. Birth details stay in your browser and are not sent to us.
