Daeun in Saju, Explained — Your 10-Year Luck Pillars and When They Begin
If your natal Saju chart is a map, Daeun are the 10-year seasons that cross it. Starting age (Daeun-su), forward vs. reverse motion, and how to read them — in plain terms.
Daeun are the 10-Year Luck Pillars of Saju — big, decade-long chapters of luck whose starting age (the Daeun-su) and direction (forward or reverse) are set by the yin-yang of your birth-year Heavenly Stem and your sex, so they differ from person to person. Your natal Saju chart (Myeongsik) is a map fixed at birth — but time keeps moving across that map. Those decade-long chapters of the journey are the Daeun. Even with the exact same chart, life takes on a very different color depending on which Daeun you're passing through right now. You can see your own chart and Daeun with the free Saju chart (Manseryeok), and if the eight characters are still unfamiliar, start with how to read a Saju chart (Myeongsik).
At a glance
- A Daeun is a major luck cycle that changes every ten years.
- Daeun set out from the Month Pillar (Wolju) and move through the stem-branch pairs in order.
- The age at which your Daeun begin is called the Daeun-su, and it's different for everyone.
- The direction — forward or reverse — is set by the yin-yang of your birth-year Heavenly Stem plus your sex.
- Check your own Daeun with the free Saju chart (Manseryeok).
What exactly is a Daeun?
A Daeun is the flow of stem-branch pairs that passes over the fixed board of your chart, one pair per decade. If the Wonguk (natal chart) answers "who am I?", the Daeun answers "what season of life am I in right now?" That's why the same chart reads in completely different colors in its twenties Daeun than in its fifties Daeun.
Daeun-su — the age your Daeun begin
Daeun don't start the moment you're born; they begin at a specific age called the Daeun-su. Traditionally, you count the number of days from the birth date to the nearest solar term and divide by three — the result is the Daeun-su. That's why one person's cycles start at two or three, and another's at nine.
Forward and reverse motion
Whether your Daeun move forward through the stem-branch sequence (sunhaeng) or backward through it (yeokhaeng) follows a fixed rule.
- Yang-year men and yin-year women (birth-year Heavenly Stem is yang / yin): forward
- Yin-year men and yang-year women (birth-year Heavenly Stem is yin / yang): reverse
If your natal Saju chart is the map, Daeun are the seasons that pass over it.
How to read a Daeun
A Daeun is never read on its own — it's read through its interplay with the natal chart. A Daeun that supplies an element your chart is short on arrives like a tailwind; one that feeds an element you already have in excess can tip into overload. So "a good Daeun" or "a bad Daeun" is never absolute — it comes down to what your own natal chart needs.
Frequently asked questions
If my Daeun is good, does everything go well?
A Daeun that supplies what your natal chart needs makes it easier to catch the current, but no single Daeun decides everything. The natal chart, the Daeun, and the year's luck (Seun) all work together.
What's the difference between Daeun and Seun?
A Daeun is the big ten-year flow; Seun (Annual Luck) is the flow of a single year. Think of the weather (Seun) changing year by year inside a larger season (Daeun).
Why is the Daeun-su different for everyone?
Because the distance in days between the birth date and the nearest solar term is different for everyone. That day count divided by three sets the starting age, which is why Daeun-su varies from person to person.
Is the changeover between Daeun a time of big change?
Many readers treat the years around a Daeun changeover as a transition where the current shifts. That said, it's more natural to picture the color changing gradually than a switch flipping overnight.
