What Is Saju?

Updated October 7, 2026

Saju (사주) is the Korean name for the Four Pillars of Destiny: a way of describing a person through the calendar characters of the year, month, day and hour they were born. It is the Korean form of what Chinese speakers call Bazi, and in Korea it is still an everyday word — heard in cafés, before weddings and every Lunar New Year.

What does saju mean?

사주 is written 四柱 in Chinese characters: 四 (sa, “four”) and 柱 (ju, “pillar”). The four pillars are the year, month, day and hour of your birth, each written as a pair of characters from the traditional calendar. Four pairs make eight characters, which is why the full name is 사주팔자 (saju palja, 四柱八字) — “four pillars, eight characters”. 팔 (pal) means “eight” and 자 (ja) “character”.

In daily Korean the two halves lead separate lives. “Let’s go get our saju read” (사주 보러 가자) is something friends say on a Friday night, while palja on its own has become a word for one’s lot in life. More on that below.

How do you pronounce saju?

Say it roughly “sah-joo”. The a is the open “ah” in father, the u is the “oo” in moon, and the j between the vowels sounds close to an English j. Korean does not stress syllables the way English does, so keep both syllables even: “SAH-joo” with a heavy first beat sounds slightly off to Korean ears.

Palja is said “pahl-jjah” — Koreans pronounce it with a tense j, as if written 팔짜. Both spellings follow the Revised Romanization of Korean, the official system in South Korea since 2000, so they are the forms you see on Korean signs and websites.

What are the four pillars made of?

Each pillar is a pair: a Heavenly Stem on top (천간, cheongan) and an Earthly Branch underneath (지지, jiji). There are ten stems and twelve branches. Paired in order they form a cycle of sixty combinations (육십갑자, yuksip gapja) — the same cycle that gives Korean years names like 병오년 (byeongo-nyeon), the Red Horse year of 2026.

• Year pillar — changes at Ipchun (입춘), the start of spring around February 4, not on January 1 or on the Lunar New Year.
• Month pillar — changes at the twelve solar terms that open each month, which fall around the 3rd to 9th of each Western month.
• Day pillar — follows an unbroken sixty-day count that has run for well over two thousand years, independent of months and years.
• Hour pillar — twelve two-hour blocks, starting with the Rat hour around midnight.

Every stem and branch also carries one of the five elements — wood, fire, earth, metal and water — and is either yin or yang. The ten stems are simply the five elements in a yang and a yin version: 갑 (Gap) is yang wood, 을 (Eul) yin wood, 병 (Byeong) yang fire, and so on. The twelve branches are the same twelve animals as the Korean zodiac. If you don’t know your birth time, you get three pillars and six characters, and most readers work with that.

What is the Day Master?

The stem of your day pillar — 일간 (ilgan), the Day Master — stands for you. Every other character in the chart is read by how it relates to that one: does it feed your element, match it, or press on it? This day-centered method is usually credited to the Chinese scholar Xu Ziping around the 10th century; older systems leaned on the year instead.

There are ten possible Day Masters, from yang wood to yin water. Each has a traditional image — yang wood is a tall tree, yin fire a candle flame, yang water a river — and readers use that image as a starting point for talking about temperament. You can read all ten on our Day Master page. The relationships between the Day Master and the other seven characters have their own names, the Ten Gods, and the chart is paired with ten-year luck pillars that describe changing seasons of life.

How do Korean people use saju today?

Most Koreans are not devoted believers, but almost everyone has had a reading at some point. The common settings:

• Saju cafés (사주카페) — a reading over coffee, popular with university students and couples, mostly for fun. Older shops often call themselves 철학관 (cheolhakgwan, “philosophy house”), and apps now offer the same thing on a phone.
• Gunghap (궁합) — comparing two people’s charts before marriage. In earlier generations families took it seriously; today it is more often a conversation starter or a bit of reassurance. Try our compatibility check.
• New Year fortunes (신년운세) — around Seollal, the Lunar New Year, many people look at the themes of the year ahead. See our 2027 forecast or the daily reading.
• Tojeong Bigyeol (토정비결) — a separate New Year tradition, a book of month-by-month verses attributed to the 16th-century scholar Yi Ji-ham (이지함), whose pen name was Tojeong. It uses your age and lunar birth month and day rather than the four pillars, so it is a cousin of saju, not the same thing.

What does “palja” mean in everyday Korean?

Outside fortune-telling, 팔자 simply means “one’s lot” — the hand life dealt you. People who have never had a reading use it all the time:

• 팔자가 좋다 (palja-ga jota) — “to have a good lot”, said of someone whose life looks easy, often with a teasing tone.
• 팔자려니 하다 (palja-ryeoni hada) — “to take it as one’s lot”, the shrug you give something you can’t change and have decided not to fight.
• 개 팔자가 상팔자 (gae palja-ga sang-palja) — “a dog’s lot is the best lot”, said while watching the family dog nap in the sun as everyone else rushes to work.

The tone of these idioms is worth noticing. Palja is talked about with humor and a bit of resignation, not with dread — closer to “that’s life” than to a prophecy.

Is Korean Saju the same as Chinese Bazi?

Yes, at the core. The system came to Korea from China centuries ago, and a Korean almanac and a Chinese almanac produce the same eight characters for the same moment and place. The differences are habits: Korean readers usually correct the birth time for longitude, use Korean names for every term, and pay extra attention to symbolic stars (신살, sinsal) and gunghap. Our Saju vs Bazi guide compares them side by side, and our Bazi calculator shows the same chart with Chinese names.

How can I get my own saju chart?

You need your date of birth, your birth time if you know it, and your birth city. Our free Saju calculator converts the time to local solar time for that city, applies historical daylight saving (Korea used it in 1987 and 1988, among other years), finds the solar terms, and shows your eight characters along with your Day Master, element balance and Ten Gods. If your family only knows your Korean lunar birthday, tick the lunar box and the calculator converts it. If you don’t know the time, leave it out and you get six characters.

Is Saju accurate?

Honestly: there is no scientific evidence that birth charts predict personality or events, and controlled studies of astrology-style systems have not found effects. Saju is best understood as a centuries-old vocabulary for reflection — a structured way to ask “what am I like, and what kind of season am I in?”

Where accuracy does matter is the calculation. A chart built on the wrong time zone or the wrong solar-term moment gives the wrong characters, and the whole conversation starts from a mistake. We compute the characters precisely, test our engine against an independent almanac library, and treat the interpretations as prompts for thought rather than verdicts.
