Daewun: Saju's 10-year luck cycles, explained
Daewun (대운, "great luck") is the layer of a Saju chart that changes over time. Starting from your month pillar, a new pillar takes over roughly every ten years and colors that decade. Readers use it to explain why the same person can feel like a different person in their twenties and thirties. Your birth chart stays fixed; the daewun is the weather passing over it.
How luck pillars are set
- They start from the month pillar and step forward or backward through the 60-pillar cycle.
- Direction depends on the year stem's yin or yang and on sex, by traditional rules.
- The starting age comes from the distance between your birth and the nearest solar term.
Daewun vs yearly luck
| Layer | Changes every | Traditionally read as |
|---|---|---|
| Daewun (luck pillar) | About 10 years | The season of your life |
| Seun (yearly pillar) | 1 year, at Ipchun | This year's weather |
FAQ
When does my daewun change?
At an age fixed by your own chart, usually the same last digit each time (for example 7, 17, 27). It differs from person to person.
Is a bad daewun a bad decade?
Modern readers frame it as a decade that asks for different strengths, not a doomed one. Treat it as weather to plan around, not a verdict.
Do I need my birth time for daewun?
The date matters most, because the start age comes from the solar terms around your birthday. The time refines it.
