Calculated to true solar time, corrected for the longitude of your birthplace and Korea's real timezone history.
MEET SAJU · 사주
Saju is Korea’s tradition of reading the year, month, day and hour you were born. Its name means “four pillars.” Together, they form a chart read for temperament, relationships and the changing seasons of a life.
Four pieces of one story. Tap to unfold.
Traditionally read for family roots and the wider social setting you begin in.
Your birth season helps shape how the five elements interact throughout the chart.
The top character of this pillar is your day master—the reference point for reading the rest.
Traditionally connected with children, later life and private ambitions. Unknown time? This pillar stays open.
Fun fact!
In traditional Korean marriage customs, families exchanged the couple’s birth information before the wedding. Saju was part of the family conversation—not just a private curiosity.

Your character, relationships and direction in life—read through the patterns in your birth chart.
A few of the many symbolic stars Saju reads, and what they traditionally suggest:
Your particular combination tells your story.
The meaning comes from how your stars and elements support or challenge one another.
Incoming years and ten-year cycles activate patterns in your chart, pointing to possible turning points.
Explore what may change—and when.
Saju offers a traditional interpretation of these patterns, rather than certainty about what will happen.

Your chart has eight characters. Each one counts once — so every share here is a multiple of 12.5%.
The ten day masters
The stem above your day pillar is the character the whole chart is read from. There are ten of them, and you have not seen yours yet.
Where it comes up
gyeolhon-un
The day branch — the seat a spouse occupies, and the years that reach it.
baeuja-un
What the day master is short of. People tend to arrive carrying it.
janyeo-un
The hour pillar, which is the children’s palace.
jigeop-un
The officer star, and how much of it the day master can actually carry.
jeokseong
Whether the chart is strong or weak at its root. Weak roots do better with a structure around them.
saeop-un
The wealth star read against the officer star — earning power against the ability to hold it.
tuja-un
Steady wealth or irregular wealth. One accumulates, the other arrives and leaves.
jaemul-un
When an incoming year feeds the wealth element instead of draining it.
wol-un
Twelve monthly pillars laid over the natal chart, one at a time.
daeun
The ten-year pillars — including the age yours starts, which the chart sets itself.
geongang-un
Which of the five is starved and which is flooded. Both show up in the body.
sinsal
The sinsal — the named stars, the ones people have heard of and worry about.
A few things before you begin
The practical answers, before your first reading.
Choose “I don’t know my birth time” instead of guessing. You can still read the year, month and day pillars. The hour pillar stays unknown, so the reading is less complete and conclusions that depend on it need caution.
They share the Four Pillars framework. Saju is the Korean tradition; BaZi is the Chinese name for the eight characters. Calculation conventions and interpretation can vary between readers.
Enter your Gregorian birth date here. If your family records a Korean lunar birthday, confirm its Gregorian equivalent first, including any leap month. Saju’s year and month boundaries follow solar terms, rather than January 1 or Lunar New Year.
In the Saju tradition, a reading explores where your fate is leaning: the patterns in your chart and the periods interpreted as more supportive or challenging for love, work and money. It gives you a way to think about what to pursue, what to prepare for and when to act. These are interpretations of potential, rather than scientifically established predictions or guaranteed events. Your choices and circumstances still shape what happens.
Yes. Readings explore relationship patterns, working styles and timing. They cannot identify a guaranteed soulmate, promise a windfall or decide whether you should marry or change jobs. Bring a specific question about the choices in front of you.
Your birth chart stays the same unless you correct the birth details. You can revisit its interpretation when your question or life circumstances change; you do not need a fresh reading every day.
Your chart and initial reading are free, with no account required. In-depth personal readings are paid. Every personal reading you buy includes one free question to the Well. Additional threads and paid continuations use Lumens.
