How to find the Conception
Count from the Day Master: Yang stems forward from Birth, Yin stems backward. Jia's Birth is Hai, so ten steps forward, You, is Jia's Conception; Yi's Birth is Wu, so ten steps backward, Shen, is Yi's Conception. The table shows the Conception branch for each of the ten Day Masters.
| Day Master | Branch at Conception |
|---|---|
| 甲 Jia · Yang Wood | 酉 You |
| 乙 Yi · Yin Wood | 申 Shen |
| 丙 Bing · Yang Fire | 子 Zi |
| 丁 Ding · Yin Fire | 亥 Hai |
| 戊 Wu · Yang Earth | 子 Zi |
| 己 Ji · Yin Earth | 亥 Hai |
| 庚 Geng · Yang Metal | 卯 Mao |
| 辛 Xin · Yin Metal | 寅 Yin |
| 壬 Ren · Yang Water | 午 Wu |
| 癸 Gui · Yin Water | 巳 Si |
What Conception means traditionally
Conception is the start of a new cycle: everything is still brewing, full of possibility but not yet formed. A Day Master sitting on Conception is traditionally described as curious, optimistic and imaginative, fond of planning and trying new things, but with more ideas than follow-through, needing time for plans to mature.
Its strength is slight, but it stands for hope. Meeting Conception in a chart is often read as something in gestation: not to be rushed, best nurtured patiently.
How to read it in a chart
- Day branch
- a Day Master sitting on Conception (e.g. Bing Zi, Ren Wu, Ding Hai, Gui Si) is traditionally read as young at heart and curious, liking freshness in relationships but also needing security.
- Month branch
- meeting Conception in the month means very little seasonal support, so the Day Master usually leans weak.
- Year and hour pillars
- Conception there is often read as a phase of gestation, or with questions of children coming to the fore.
- Luck pillars and years
- a Conception period is traditionally good for sowing, planning and learning, with results showing in later stages.
Related ideas
- Conception vs. the Conception Pillar
- the Conception Pillar (胎元) is a stem-branch pair derived from the month pillar (month stem plus one, month branch plus three), used to add detail about one's innate makeup. The life stage Conception is the Day Master's state at a branch; the two should not be mixed up.
- Termination, Conception, Nurture
- Termination ends the old, Conception begins the new, Nurture grows it in the womb, and then comes Birth.
Common misconceptions
- “Conception” in a chart does not mean pregnancy or childbirth; it is the metaphorical name of a life stage.
- Conception is not the Conception Pillar; they are found and used differently.
- 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 Conception 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.
What is the difference between the Conception stage and the Conception Pillar?
The Conception stage is the Day Master's life stage at a branch; the Conception Pillar (胎元) is a stem-branch pair derived from the month pillar (stem plus one, branch plus three). The names are similar, but the ideas are entirely different.
What does a Day Master sitting on Conception mean?
Traditionally curious, optimistic and full of ideas, best at nurturing plans patiently; if the Day Master is weak, Seals and Companions help. How it plays out depends on the whole chart.
