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.
