Korean Astrology, known as Saju (사주) or "Four Pillars of Destiny" (四柱八字), is an ancient Eastern divination system that analyzes a person's fate using their birth year, month, day, and hour.
Unlike Western astrology's zodiac signs, Saju uses a 60-year cycle based on the 10 Heavenly Stems and 12 Earthly Branches, combined with the theory of Five Elements (Wood, Fire, Earth, Metal, Water).
Practiced for over 1,000 years across Korea, Japan, China, and Vietnam, Saju reveals personality traits, career aptitudes, relationship patterns, and life cycles with remarkable depth.
Year Pillar 年柱 (년주) — Ancestors, family background, early life. Month Pillar 月柱 (월주) — Parents, siblings, youth & career path. Day Pillar 日柱 (일주) — Your core self & Day Master, the most important pillar. Hour Pillar 時柱 (시주) — Children, late life, hidden desires.
Day Master — Your core personality type, one of 10 unique Day Masters based on your birth date
Five Elements Balance — Which elements are strong or weak in your chart, and how they shape your life
Favorable Element (Yongshin) — The element that brings you luck, balance, and support
Career & Talents — Your natural aptitudes and most aligned career paths
Love & Compatibility — Your relationship patterns and ideal partner characteristics
Decade Cycles (Daewoon) — 10-year fortune cycles showing when opportunities and challenges arrive
1. Enter Birth Info — Provide your name, birth date, and birth time. Time is optional but improves accuracy.
2. AI Analysis — We calculate your Four Pillars with the solar-term (jeolgi) calendar used in Manseryeok. A lunar birth date is converted first; AI then explains the calculated chart.
3. Get Your Reading — Receive detailed analysis of your Day Master, Five Elements, personality, career, love, and life cycles.
Applying a single approximate date can change the Year or Month Pillar near a solar-term boundary. These examples compare an approximation with the solar-term timing calculated for that year.
Boundary Example #1 — Born February 3, 1990: Ipchun 1990 fell at about 11:14 on February 4 (KST), so February 3 is still the Gisa year, in the Chuk month before Ipchun. Year: 己巳 / Month: 丁丑 / Day: 己亥 — Day Master: Gi Earth (己土). Ipchun moves the Year and Month boundary, not the Day Pillar; an answer of "Gyeong Metal" mistakes the year stem for the Day Master.
Boundary Example #2 — Born February 4, 1988: Ipchun 1988 fell at about 23:43 on February 4 (KST). Born before it: Jeong-Myo Year (丁卯年), Gye-Chuk month (癸丑); born after it: Mu-Jin Year (戊辰年), Gap-In month (甲寅). On a boundary date, the birth time decides the Year and Month Pillars.
A fixed-date approximation may not look up each year or explicitly collect leap-month input. FateAIverse stores Manseryeok dates for its supported range, collects calendar settings, and applies the same documented rule to the same inputs.
Korean Astrology, known as Saju (사주) or Four Pillars of Destiny, analyzes a person's fate using the year, month, day, and hour of birth. Each pillar is expressed using the 10 Heavenly Stems and 12 Earthly Branches system.
Unlike Western astrology which focuses on planetary positions, Saju uses a solar calendar-based system with 60-year cycles. It emphasizes Five Elements (Wood, Fire, Earth, Metal, Water) interactions to reveal personality, destiny, and life cycles.
