IdolSaju is a FREE K-Pop idol compatibility calculator that uses authentic Korean Saju (사주) astrology - the Four Pillars of Destiny - to calculate your cosmic connection with over 350 K-Pop idols including BTS, Stray Kids, SEVENTEEN, NewJeans, aespa, ENHYPEN, LE SSERAFIM, IVE, RIIZE, BOYNEXTDOOR, TWS, ILLIT, BLACKPINK, and more.

How does Korean Saju astrology work?

Saju (사주) is based on the Four Pillars of Destiny: Year, Month, Day, and Hour pillars. Each pillar contains a Heavenly Stem (천간) and Earthly Branch (지지), creating a unique cosmic profile. IdolSaju compares your Saju profile with K-Pop idols to calculate compatibility based on Five Elements (오행) harmony, zodiac combinations, and energy flow.
