Decline (衰) in BaZi
The stage after the peak
Short answer
Decline (Shuai, 衰) is the sixth of the Twelve Life Stages: past the prime of life, physical energy easing off, but rich in experience and seasoned in judgement. Traditionally it stands for steadiness, caution, experience and a sense of proportion; strength no longer expands, but knows how to hold on.

How to find the Decline
Count from the Day Master: Yang stems forward from Birth, Yin stems backward. Jia's Birth is Hai, so five steps forward, Chen, is Jia's Decline; Yi's Birth is Wu, so five steps backward, Chou, is Yi's Decline. The table shows the Decline branch for each of the ten Day Masters.
| Day Master | Branch at Decline |
|---|---|
| 甲 Jia · Yang Wood | 辰 Chen |
| 乙 Yi · Yin Wood | 丑 Chou |
| 丙 Bing · Yang Fire | 未 Wei |
| 丁 Ding · Yin Fire | 辰 Chen |
| 戊 Wu · Yang Earth | 未 Wei |
| 己 Ji · Yin Earth | 辰 Chen |
| 庚 Geng · Yang Metal | 戌 Xu |
| 辛 Xin · Yin Metal | 未 Wei |
| 壬 Ren · Yang Water | 丑 Chou |
| 癸 Gui · Yin Water | 戌 Xu |
What Decline means traditionally
Decline is the stage after the peak: less drive, more experience and judgement. A Day Master sitting on Decline is traditionally described as steady, low-key and measured, not fond of risk, better at protecting what has been built.
The word sounds negative, but it describes a kind of maturity: relying on experience and rhythm rather than force. For a weak Day Master, Decline gives limited support and Seals or Companions are needed; for a strong one, sitting on Decline makes the temperament calmer.
How to read it in a chart
- Day branch
- a Day Master sitting on Decline (e.g. Jia Chen, Geng Xu, Yi Chou, Xin Wei) is traditionally read as steady, cautious and security-minded, with a slow-and-steady marriage.
- Month branch
- meeting Decline in the month means seasonal support has already faded, so judge the Day Master's strength from the other pillars.
- Year and hour pillars
- Decline there is often read as a stable phase focused on building up rather than expanding.
- Luck pillars and years
- a Decline period is traditionally a time to consolidate, tidy up and reflect rather than push forward.
Related ideas
- After Prosperity
- Decline comes straight after the peak, the turn captured in “what peaks must decline”.
- Decline and Illness
- Illness follows Decline as strength keeps waning; Decline still has reserves, Illness is clearly weaker.
Common misconceptions
- Decline does not mean failing luck or failing health; it is a life-cycle metaphor.
- A Day Master sitting on Decline is not necessarily weak; strength is judged from the month and the whole chart.
- The life stages alone cannot tell you the Day Master's strength; read them with the month, the balance of the phases and the structure.
Frequently asked questions
How do I see Decline in my own chart?
Enter your birth details in the free calculator. The life stage row shows your Day Master's stage at each branch, and the self stage row shows each pillar's stem on its own branch. You can also use the table above.
Is it bad for the Day Master to sit on Decline?
No. Traditionally it stands for steadiness and experience, calm rather than showy strength. Whether it helps depends on whether the chart needs a stronger Day Master.
How are Decline and Prosperity related?
Decline comes right after Prosperity, as strength starts to come down from its peak. Prosperity is maximum expansion; Decline is pulling in and holding on.
