1. What is Korean Saju (사주)?

Saju (사주, 四柱) literally means Four Pillars in Korean. It is the traditional East Asian practice of reading destiny by examining the eight characters (八字, 팔자) of a person's birth year, month, day, and hour. Each of those four time components contributes one Heavenly Stem (天干) and one Earthly Branch (地支), for a total of eight characters — hence the alternative name "bazi" in Chinese.

Saju shares its foundation with Chinese bazi and Japanese suimeigaku, but Korean practitioners developed distinct interpretive traditions over the Joseon dynasty (1392–1897) — especially around compatibility (궁합), career fortune (직업운), and wealth luck (재물운). Modern Korean dramas, K-pop idols in interviews, and even Seoul café subculture all reference saju casually, the way Westerners might reference astrological sun signs.

2. The Four Pillars (四柱)

Each pillar captures a slice of time in the sexagenary (60-cycle) calendar:

Year Pillar (연주, 年柱) — your "big picture" life destiny and ancestral energy.
Month Pillar (월주, 月柱) — career, social status, and ambition.
Day Pillar (일주, 日柱) — your inner self, love life, and immediate relationships. The Heavenly Stem of your Day Pillar is called the Day Master (일간, 日干) — consideredyou in most readings.
Hour Pillar (시주, 時柱) — children, later-life wisdom, and hidden talents.

3. Heavenly Stems (天干, 10) & Earthly Branches (地支, 12)

Ten Heavenly Stems — 甲 Jia, 乙 Yi, 丙 Bing, 丁 Ding, 戊 Wu, 己 Ji, 庚 Geng, 辛 Xin, 壬 Ren, 癸 Gui — cycle together with twelve Earthly Branches (the zodiac animals: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, Pig) to form the 60-year sexagenary cycle known as 갑자(甲子). Each stem has a Yin or Yang polarity, and each stem and branch maps to one of the Five Elements (오행, 五行).

Stem → element mapping: 甲乙 = Wood · 丙丁 = Fire · 戊己 = Earth · 庚辛 = Metal · 壬癸 = Water.

4. The Five Elements (五行)

Everything in saju ultimately reduces to five elements and their relationships. The two cycles are:

Generating (상생, 相生): Wood → Fire → Earth → Metal → Water → Wood …
Conflicting (상극, 相剋): Wood controls Earth, Earth blocks Water, Water extinguishes Fire, Fire melts Metal, Metal cuts Wood.

When two people's day-master elements are in a generating relationship, their energies flow together — partnership, mentorship, supportive love. When they are in a conflicting relationship, they either provoke growth or grind each other down. Neutral and "same-element" pairings lean stable but can feel unchallenging.

5. Zodiac Compatibility (띠 궁합)

On top of elements, saju compatibility looks at branch-level relationships:

Trinity / 三合: three-animal harmony groups — Monkey·Rat·Dragon (Water), Pig·Rabbit·Sheep (Wood), Tiger·Horse·Dog (Fire), Snake·Rooster·Ox (Metal). Same-group pairs amplify each other.
Harmony / 六合: six classic pair bonds — Rat-Ox, Tiger-Pig, Rabbit-Dog, Dragon-Rooster, Snake-Monkey, Horse-Sheep.
Clash / 沖: opposite-branch pairs (6 apart) — Rat-Horse, Ox-Sheep, Tiger-Monkey, Rabbit-Rooster, Dragon-Dog, Snake-Pig. Clashes often mark volatility: great for passion, rocky for roots.

In this tool we combine day-master element relation (generating +30, same +10, conflicting −20) with year-branch relation (trinity +15, harmony +10, clash −15) around a base of 50 — producing a 0-to-100 compatibility score. It is a simplification, of course, but it matches the intuitions most K-pop fans have when they talk about "idol energies clicking".

6. Reading Fortune in 2026

2026 is the year of the Fire Horse (丙午) in the 60-cycle. Fire types will feel energized but should avoid burnout; Water types get an opportunity year for negotiation; Wood types benefit from slow, steady growth; Earth types should lean into stability plays; Metal types must resist over-committing to shiny-object projects.

7. Wealth in Korean Tradition

Wealth in saju is less about raw income and more about the type of money-energy that flows through your chart. A "Growing Tree" (Wood) wealth type compounds slowly through long projects; a "Bright Flame" (Fire) type gets sudden windfall opportunities; "Steady Mountain" (Earth) thrives in real estate; "Sharp Blade" (Metal) excels at disciplined investing; "Flowing River" (Water) builds wealth through networks and international trade.

8. How this website calculates your saju

We use the simplified Gregorian-year modulo convention to compute the year stem and branch, a derived month pillar via the 五虎遁 (five tigers) table, and a day pillar anchored to the 1900-01-01 reference (that day was 甲戌 in the traditional table). Hour pillars use the 2-hour block starting at 23:00 and derive the stem from your day-master via the 五鼠遁 (five rats) table. The Day Master element (일간) is treated as your primary saju element.

Note: real Korean 만세력 (perpetual-calendar) engines use lunisolar conversion and solar-term (節氣) rules, which can shift your month pillar by one block. For entertainment-level insights our approximation is fine; for serious consultation please visit a traditional saju reader in Korea.

9. A note on K-pop celebrity compatibility

The K-celebrity presets in our Compatibility tool use only publicly reported birth dates — the same information you'd find on an official fan-club or agency profile. We intentionally do not use any photos, logos, album covers, or other copyrighted assets from HYBE, SM, YG, JYP, ADOR, or any other management. Names are used in a purely descriptive and non-endorsing way. This site is not affiliated with any agency, artist, or management.

10. Final caveats

Saju is a centuries-old cultural framework and a beautiful lens for reflection — but it is not science. This site is built for entertainment, global K-culture discovery, and fun conversation with friends. Do not make life, medical, or financial decisions based on these results. When in doubt, talk to a qualified professional and follow local legal and regulatory guidance.

11. 한국 사주의 12 띠와 60갑자 — 한 번 더 한국어로

한국 전통의 사주(四柱)는 사람의 출생 연·월·일·시 네 기둥(柱)에 각각 천간(天干) 하나와 지지(地支) 하나를 배치해 모두 8글자(팔자, 八字)를 뽑는 방식입니다. 천간 10개(甲乙丙丁戊己庚辛壬癸)와 지지 12개 (子丑寅卯辰巳午未申酉戌亥)가 결합해 60년 주기의 갑자(甲子) 순환을 이루며, 같은 갑자가 다시 돌아오는 만 60세를 환갑(還甲)이라 부르는 것이 여기서 비롯되었습니다.

12 지지는 흔히 12 띠로 알려진 동물 상징(쥐·소·호랑이·토끼·용·뱀·말·양·원숭이·닭·개·돼지)과 일대일 대응합니다. 띠 자체는 출생 연도의 지지로 결정되지만, 사주에서는 일간(日干, Day Master)을 본인으로 보고 그 사람의 본질을 읽기 때문에 단순한 "띠별 운세"와는 차원이 다릅니다. 일간이 어떤 오행이며 다른 일곱 글자가 그 오행을 도와주는지 깎아내리는지에 따라 직업운·재물운·궁합·건강운이 모두 갈립니다.

12. 사주를 보는 한국 문화의 맥락

한국 사회에서 사주는 단순한 미신이 아니라 결혼·이사·창업·취업처럼 인생의 큰 결정을 앞두고 마음을 정리하는 도구로 활용되어 왔습니다. 명동·인사동·신촌 일대에 전문 사주카페가 자리잡고, MZ 세대도 데이트 코스로 즐겨 찾을 만큼 대중적입니다. 본 사이트는 이러한 문화적 맥락 안에서 가볍게 즐길 수 있도록 만든 무료 도구이며, 정확한 만세력 기반 사주 풀이는 전문 역술인에게 직접 상담받기를 권합니다.

13. 본 도구가 적용한 단순화

그레고리력 기준 연도 모듈로 연주 천간·지지를 계산합니다.
월주는 5호둔(五虎遁) 표로 연간에서 파생합니다.
일주는 1900-01-01을 갑술(甲戌)로 보는 기준일을 사용합니다.
시주는 23시 시작 2시간 블록으로 묶고 5서둔(五鼠遁) 표로 시간 천간을 도출합니다.
음력·24절기 보정은 적용하지 않아 정통 만세력과 월주에서 ±1 블록 차이가 날 수 있습니다.

14. 면책 — 엔터테인먼트 목적

본 사이트는 한국 사주 문화를 글로벌 K-컬처 팬에게 소개하기 위한 엔터테인먼트 도구입니다. 인생의 중요한 결정(결혼·이혼·이직·투자·의료·법률)은 반드시 자격을 갖춘 전문가와 상의하세요. 본 도구의 결과는 어떠한 예측이나 보장도 제공하지 않으며, 한국 사주 문화에 대한 흥미와 대화 소재로만 활용하시기 바랍니다.
