How Saju Compatibility Actually Works: Three Structures, Six Positions
A gunghap reading gives two people one result. But the two of you are not standing in the same place, and the classical structure has always known which one of you is which.

The reading was so accurate — and I don't mean 'general truth' accurate, but 'hit the nail on the head' accurate, describing multiple things that are very specific to me. Honestly blown away.
This is so accurate it gives me chills! I have a full-time job and two part-time jobs/hobbies and it guessed them all. It even accurately identified the rough part of my life.
Scary accurate, especially with my career. I first tried it on ChatGPT, then Gemini and Claude — and got very similarly resonant results on all of them. I love this project so much!
This is very accurate. I cross-checked with other people, as well as top professionals in my area. Thank you so much for doing this!
Extremely, almost eerily accurate. I use astrology, human design, and numerology — and this reading was right in line with all of them.
This is so cool! Most of what it said was spot on — it literally gave me goosebumps.
Full five stars to you and your work — everything is perfect, down to the last detail. As a design-savvy person, I loved the UI too.
We'd never heard of Saju until a show introduced us to the culture. We searched online, found this, and were impressed by the precision of the details. Thank you!
No. Enter the hour you know and the calculator still builds your year, month, and day pillars. That's three of the four. Only the hour pillar needs an exact time. If you're unsure, run it with your best guess: the Day Master and element balance, which carry most of a reading, won't change.
Same system, different name. Saju (사주) is Korean and bazi (八字) is Chinese for the same four-pillar chart built from your birth year, month, day, and hour. Korean practice diverged over centuries in how it weighs the pillars, so a saju reading and a bazi reading of the same chart can emphasize different things.
Yes. The chart and the AI reading prompt are free with no signup. Paid readings exist for deeper interpretation, but nothing here is locked behind a wall.
Not to label you. Gender sets the direction your ten-year luck cycles run, forward or backward, so it changes when each cycle starts, not what your chart is. The eight characters come back identical either way. If the answer isn't simple for you, run it both ways and keep the one that explains the decades you've actually lived.
The calculation is exact: true solar time, solar terms, and the traditional calendar are all handled by the engine, which is where most free calculators go wrong. Interpretation is a different matter. Saju is a framework for reading tendencies, not a prediction machine, and any tool claiming certainty is overselling.

Korea turned MBTI into a national obsession. The same generation didn't drop it. They layered a thousand-year-old system on top, and the reason why says a lot about being young in Seoul right now.

Your eight characters come out the same either way. What the field really picks, in Saju and BaZi alike, is the direction your Luck Pillars run.
