Decoding Your Destiny: Understanding the 10-Year Life Cycles
In Saju astrology, your fate isn't static. Learn about 'Daewun' (10-year cycles) and 'Seun' (yearly luck) to understand why life shifts and how to navigate your current cosmic season with Solzigi.
"What's my luck this year?" - The Deeper Meaning
When the New Year approaches, everyone asks, "How is my luck this year?" But have you ever stopped to wonder?
If we are born with a fixed birth chart, why does our luck change every year?
The answer lies in the core engines of Sajuology (Korean Astrology): Daewun (The Major Cycle) and Seun (The Annual Cycle).
Today, let's dive into how to read the macro waves of your life and the micro ripples of the year.
Two Timelines of Fate: The Blueprint vs. The Journey
In Saju, we look at two distinct dimensions of time to understand a person's life.
The Blueprint (Pre-destined Fate)
Your Saju Palja (Four Pillars of Destiny) consists of the 8 fixed characters determined the moment you were born. We call this the Original Chart.
This blueprint does not change. You carry these 8 characters with you for your entire life, like your spiritual DNA.
The Journey (Post-destined Fate)
However, life cannot be explained by a static blueprint alone. As time flows, you encounter different environmental energies. This is the Evolving Fate.
Think of it this way:
| Type | Duration | Meaning |
|---|---|---|
| Daewun (Major Cycle) | 10 Years | The "Season" of your life; the macro theme. |
| Seun (Annual Cycle) | 1 Year | The specific vibe or events of that year. |
| Wolun (Monthly Cycle) | 1 Month | The subtle flow of the month. |
| Ilun (Daily Cycle) | 1 Day | The energy of the day. |
๐ก If your Birth Chart is the Ship, then Daewun and Seun are the Ocean and the Winds. Even the best ship needs to navigate the waves.
Daewun (ๅคง้) - The 10-Year Season of Life
What is Daewun?
Daewun is a major shift in energy that happens every 10 years. It represents the "Big Theme" of that decade.
Even with the exact same birth chart, a person will live a completely different life in their 20s versus their 40s because the Daewun changes. Some might struggle in their youth only to bloom late in life, depending on these cycles.
Think of Daewun as the Seasons of Life. Just as you plant seeds in spring, grow in summer, harvest in autumn, and rest in winterโeach 10-year cycle requires a different life strategy.
How is it Determined?
Daewun is calculated based on your Month Pillar (the month you were born).
Depending on your gender and the year you were born (Yin or Yang year), the cycle flows either forward or backward through the zodiac.
The "Daewun Number" - When Does Your Season Change?
Everyone has a specific age when their 10-year cycle shifts. This is called the Daewun Number. It usually falls between ages 1 and 10.
For example, if your Daewun Number is 3, your major life themes will shift at ages 3, 13, 23, 33, 43, and so on.
The Structure: Heaven and Earth
Like your birth chart, a Daewun cycle consists of two characters: a Heavenly Stem and an Earthly Branch.
- Heavenly Stem: Influences the first 5 years (Mental/Social environment).
- Earthly Branch: Influences the latter 5 years (Physical/Reality).
While they work together for the full 10 years, the focus tends to shift from the ideal (Heaven) to the reality (Earth) as the decade progresses.
Seun (ๆญฒ้) - The Annual Weather
What is Seun?
Seun is the energy of the specific year affecting your chart.
For instance, 2026 is the Year of the Fire Horse (Bing-O, ไธๅ). The intense energy of Fire will affect everyone globally.
However, the impact is personal. If your chart is cold and needs warmth, 2026 could be your best year. If your chart is already too hot, it might be a year to stay cool and cautious.
How to Read the Year
To accurately predict your year, you must look at the "Trinity of Fate": Your Birth Chart + Current 10-Year Cycle + This Year's Energy.
- Is the year your "Guardian Element"? โ Likely a year of growth and success.
- Is the year your "Challenging Element"? โ A year to be conservative and careful.
- How does the year interact with your 10-Year Cycle? โ Harmony brings smoothness; conflict brings change.
- Are there Clashes or Mergers? โ Expect significant events or shifts in relationships.
The Interaction: Waves and Ripples
You cannot look at the 10-Year Cycle and the Yearly Cycle separately. They dance together.
When the 10-Year Cycle (Daewun) is Good
- Meeting a Good Year: Massive success, expansion, and "flow state."
- Meeting a Bad Year: You might face minor setbacks, but the overall foundation remains strong. You are protected.
When the 10-Year Cycle (Daewun) is Difficult
- Meeting a Good Year: A breath of fresh air. A moment of relief and hope in a tough season.
- Meeting a Bad Year: The "Winter of Life." It's time to hibernate, study, and prepare for the future rather than take risks.
๐ Daewun is the massive current of the ocean. Seun is the wave on the surface. If the current is with you, a choppy wave won't stop you. But if the current is against you, even a small wave can rock the boat.
Wolun (ๆ้) - The Monthly Vibe
Beyond the year, we have the Monthly Luck. In Saju, months are not based on the Gregorian calendar (Jan 1st) but on Solar Terms.
The Astrological Calendar
| Solar Term | Approx. Date | Zodiac Month |
|---|---|---|
| Start of Spring | Feb 4th | Tiger (ๅฏ ) |
| Awakening of Insects | Mar 6th | Rabbit (ๅฏ) |
| Clear and Bright | Apr 5th | Dragon (่พฐ) |
| Start of Summer | May 6th | Snake (ๅทณ) |
| ... | ... | ... |
| Start of Winter | Nov 7th | Pig (ไบฅ) |
| Heavy Snow | Dec 7th | Rat (ๅญ) |
| Minor Cold | Jan 6th | Ox (ไธ) |
๐ Note: The Saju New Year begins around February 4th (Start of Spring), not January 1st!
Favorable vs. Challenging Cycles
Signs of a "Golden Era" (Good Daewun)
โ Guardian Element Arrives: The energy your chart desperately needs finally appears. โ Harmonious Flow: Your chart and the timeline are in sync.
What happens:

Signs of a "Training Era" (Challenging Daewun)

- Results don't match the effort put in.
- Unexpected obstacles arise.

The "Shift": When the 10-Year Cycle Changes
The period just before and after your Daewun changes (usually a 1-2 year window) is known as a Turbulence Zone.
Common Symptoms of the Shift
- Career: Sudden desire to quit, change industries, or unexpected promotion.
- Relationships: Breakups, new intense connections, marriage, or divorce.
- Environment: Moving houses or emigrating to a new country.
- Mindset: Your values, tastes, and personality seem to change overnight.
How to Navigate the Shift

- Embrace the change: Don't fight the current; accept that a new chapter is starting.
- Health check: Your body is adjusting to new energy; rest well.
- Declutter: Finish unfinished business from the last decade.
- Set new coordinates: Re-evaluate your goals for the next 10 years.
