Ever wonder how well you'd actually click with your bias? K-pop idol compatibility uses traditional Korean Saju (사주) and Gunghap (궁합) to gently compare your personalities, energy, and the ways you fit together.
Saju reads your birth year, month, day, and hour through the five elements (오행). Placing two charts side by side shows where you naturally vibe and where you simply differ — that's the heart of bias compatibility.
It's not a verdict — it's for fun. Enjoy it lightly, and share the parts you love with your friends 💞
Your birthday + your bias — free, 30 seconds.

Idol compatibility (gunghap) compares your Korean Saju (사주) elements with your bias's birth chart to show where your personalities click and where they differ. It's a warm, playful way to feel closer to your favorite — purely for fun.
Yes, it's free and there's no sign-up to check your idol compatibility. Just enter your birth info, pick your bias, and you'll see your match right away.
We add popular K-pop idols using only publicly known names and birthdays. Browse the list below and tap any idol to see your compatibility — the directory keeps growing.
It's made for entertainment and self-reflection, not professional advice. Idol compatibility is a fun conversation starter about personalities and energy — enjoy it lightly and keep loving your bias your own way.
Your birthdate becomes four Saju pillars, and the five elements (Wood, Fire, Earth, Metal, Water) that come out of them are placed next to your bias's. When they feed each other (the generating cycle: Wood→Fire→Earth→Metal→Water→Wood) the score rises; when one overcomes the other (skipping one place) you pull apart. The table above is the whole rule.
Yes — the date alone is enough. Compatibility on this page doesn't use your birth time at all; it compares the elements drawn from your year, month and day pillars. Knowing the hour makes your own reading finer, but it isn't needed for matching with your bias.
Free, just for fun. All you need is your birthday to start.
