Major Luck Cycles & Annual Fortune

The Major Luck Cycle (Daeun) is one of the most important timelines in Saju analysis — a large-scale fortune that shifts roughly every 10 years. If the natal chart (Wonguk) is the "map," the Daeun is the "season and weather." The Daeun progresses forward (for Yang males and Yin females) or backward (for Yin males and Yang females) from the Month Pillar. The first Daeun begins at an age found by counting the days between birth and the next solar term (or the previous one, if the Daeun runs backward) and dividing by three. Annual Fortune (Seun) changes every year. For example, 2026 is a Byeong-O year, where Byeong Fire and O Fire overlap, making it a year of strong fire energy. Depending on how the Daeun and Seun interact with the natal chart: ● When an element the natal chart lacks arrives via Daeun → blocked matters open up or new opportunities emerge ● When the Daeun clashes (Chung) with the natal chart → major changes — career shifts, relocation, relationship changes ● When the Daeun harmonizes (Hap) with the natal chart → good connections, stability, fruition This is why people with the same natal chart often experience similar life themes during the same Daeun period. It is the reason Saju is called the study of "reading timing." A common real-life example of how Major Luck Cycles work is the person who struggles through their early twenties with studies and career, only to suddenly thrive upon entering their thirties. This can be the result of a new Daeun bringing in the very Five-Element energy their natal chart was missing. Conversely, someone who enjoyed great success in youth may find business suddenly faltering or health problems emerging after a certain age, closely tied to a Daeun transition. In this way, the Daeun works like a weather vane, showing which way the wind of your times is blowing, regardless of individual effort. Many people confuse the Daeun with the Seun, but understanding their difference is crucial. The Daeun is a background energy spanning a full ten-year cycle, while the Seun is a one-year layer on top of it that shapes the specific events of that year. To use an analogy, if the Daeun is which city you live in, the Seun is what the weather is like in that city this year. Therefore, even with a favorable Daeun, a difficult Seun can bring temporary hardship. And even under an unfavorable Daeun, a good Seun year can open a brief window of opportunity. The key insight is that accurate timing analysis requires reading the Daeun and Seun together. People often feel anxious when told their Daeun is unfavorable, but this is a significant misconception. A clash occurring during a Daeun does not mean only misfortune will follow. Because a clash is the energy of change, it can also serve as a turning point that breaks through stagnation and propels one in a new direction. In fact, major life decisions such as career changes, relocations, marriages, and starting a business frequently happen during clash periods. What matters is not fearing change itself, but understanding its nature in advance and preparing for it. The transition period between Major Luck Cycles — roughly one to two years before and after a Daeun shift — deserves particular attention. During this window, the energy of the previous Daeun ebbs while the new Daeun's energy flows in, naturally recalibrating the direction of one's life. Career pivots, residential moves, and significant relationship changes tend to cluster around these transitions. Knowing this timing in advance allows you to respond proactively rather than being swept along by change. DESTIGER visualizes the Daeun and Seun analysis, showing users what phase they are currently in and what changes lie ahead. Rather than a simplistic good-or-bad binary, it provides specific guidance on which Five Elements strengthen or weaken during each Daeun period, and consequently which themes in career, health, and relationships come to the fore. This allows users to survey their entire life trajectory from a bird's-eye view and build strategies tailored to each phase. You cannot change your Daeun, but knowing it elevates the quality of every choice you make.
