Major Cycles (大運) and Annual Cycles (歲運)

If your natal chart is your "dealt hand," major cycles and annual cycles are your "changing environment." Even great cards mean nothing in poor conditions; modest cards can shine in the right environment. Major cycles are 10-year trends; annual cycles are 1-year shifts. Analyzing both reveals what may happen in specific periods. When fortune is "good," yongsin (necessary elements) are flowing in.

Major cycles progress forward (順行) or backward (逆行) from the month pillar. Yang males and yin females progress forward; yin males and yang females progress backward. Major cycle changes happen at different ages for different people, typically between 1–9 years old, then every 10 years after. The heavenly stem dominates the first 5 years; the earthly branch dominates the next 5. When major cycles change, life's atmosphere shifts dramatically. Career changes, marriage, moving, health changes — major life transitions often align with major cycle shifts.

Each year's annual cycle is determined by how that year's stems and branches interact with your chart. Yearly shifts in energy bring different fortune colors. 2026 is the Byeong-O (丙午, Fire Horse) year — both stem and branch are fire. It's a fiery year; those needing water yongsin face challenges, while those with fire yongsin experience vitality. Annual cycles work within the major cycle framework. Good major and annual cycles together form optimal timing; bad cycles together require extra caution.

Cycle stems and branches interact with your natal chart: Combination merges two characters into new energy. Good combinations bring opportunity; bad ones bring unwanted entanglement. Clash means direct collision. Moving, job change, separation — sudden shifts. Not always bad; blockages can break open. Penalty harms — legal disputes, health issues. Break ends relationships or plans. When working with yongsin, good. When working against yongsin, caution needed.

Yongsin periods bring promotions, passing, wealth increase, good connections. The time to be active and take chances. Inauspicious periods bring hardship, loss, conflict. Seem negative but become growth through trials, preparing for yongsin periods ahead. Important: Don't rest on yongsin periods; don't despair in inauspicious ones. Knowing fortune flow lets you prepare.

Major cycle analysis guides important decisions: Career: Knowing which cycles favor you helps time job changes or startups. Marriage: Cycles favoring spouse elements signal likely good connections. Health: Excessive or deficient elements point to organs needing care — wood relates to liver, fire to heart, earth to stomach, metal to lungs, water to kidneys. Major cycle flow lets you see 10–20 years ahead.
