How MBTI × Saju works
We treat your MBTI type as the outside, how you come across, and the character that stands for you in saju (your Day Master, 日干) as the inside you were born with. 16 types × 10 characters = 160 combos.
Whether your outside and inside match comes from MBTI E/I versus the yin or yang of your inside character. The “when the two meet” line pairs the four MBTI temperaments (NT, NF, SJ, SP) with the five elements. Your best match uses a common MBTI pairing plus the character that naturally pairs with yours.
The math runs on your device, and share links only carry your MBTI and your inside character. It’s for fun and self-reflection.

MBTI × Saju FAQ
How do you combine MBTI and saju?
Your MBTI is the outside and the character that stands for you (Day Master) is the inside. We compare E/I with its yin or yang to tell you whether they match or flip, then pair your MBTI temperament with that character’s element for a one-line read on how they blend.
What is a day master?
It’s the top character of the day you were born, the one that stands for you in a saju (bazi) chart. There are ten, from 甲 Tree to 癸 Rain.
Do I need my birth time?
No. That character comes from your birth date, so the time isn’t needed. If you were born between 11 pm and 1 am, though, the day count can shift and change it.
Is my birth date sent anywhere?
No. Your inside character is worked out on this device, and share links only carry your MBTI and a character number. Your birth date isn’t in any link.
Is it free?
Yes. The result, story image and share link are all free. Longer readings, like the full life reading and two-person compatibility, open with Tteok, the site’s credits.
