What is the Hour Pillar in BaZi (Four Pillars)?
BaZi (Four Pillars) is a Chinese metaphysical system that uses a person's birth year, month, day, and hour to analyze destiny. Each pillar consists of a Heavenly Stem (top) and an Earthly Branch (bottom). The four pillars are Year, Month, Day, and Hour. The Hour Pillar, as the name suggests, is derived from the exact hour of birth and is the last pillar in the chart.
Role of the Hour Pillar
In BaZi, each pillar represents a different life domain:
- Year Pillar: ancestry, early childhood (before age 16).
- Month Pillar: parents, career, youth (ages 16–32).
- Day Pillar: self and spouse, middle age (ages 32–48).
- Hour Pillar: children, students, subordinates, late fortune (after age 48), and later-life relationships.
The Hour Pillar is especially important for assessing one's later years, post-retirement career, and relationship with children. A favorable Hour Pillar may indicate a comfortable old age and successful offspring, while an unfavorable one might suggest challenges in these areas.
How to Determine the Hour Pillar
The Hour Pillar consists of an Hourly Heavenly Stem and an Hourly Earthly Branch.
#### 1. Determining the Earthly Branch
The Earthly Branch is based on the two-hour interval of the birth time, using the 12 Chinese zodiac animals:
| Time interval | Earthly Branch |
|---|---|
| 23:00–01:00 | Rat (Zi) |
| 01:00–03:00 | Ox (Chou) |
| 03:00–05:00 | Tiger (Yin) |
| 05:00–07:00 | Rabbit (Mao) |
| 07:00–09:00 | Dragon (Chen) |
| 09:00–11:00 | Snake (Si) |
| 11:00–13:00 | Horse (Wu) |
| 13:00–15:00 | Goat (Wei) |
| 15:00–17:00 | Monkey (Shen) |
| 17:00–19:00 | Rooster (You) |
| 19:00–21:00 | Dog (Xu) |
| 21:00–23:00 | Pig (Hai) |
#### 2. Determining the Heavenly Stem
The Hourly Heavenly Stem depends on the Day Stem (the Heavenly Stem of the Day Pillar). The rule follows the 60-year (or 60-day) cycle of the sexagenary system. A simplified table is:
| Day Stem | Stem at Rat hour | Stem at Ox hour | ... |
|---|---|---|---|
| Jia (甲) or Ji (己) | Jia | Yi | ... |
| Yi (乙) or Geng (庚) | Bing | Ding | ... |
| Bing (丙) or Xin (辛) | Wu | Ji | ... |
| Ding (丁) or Ren (壬) | Geng | Xin | ... |
| Wu (戊) or Gui (癸) | Ren | Gui | ... |
For example, if the Day Stem is Jia, the Rat hour will have stem Jia, Ox hour Yi, Tiger hour Bing, and so on.
Detailed Interpretation
In practice, the Hour Pillar is analyzed via:
- Five Elements: The interaction (generating or controlling) between the stem and branch of the Hour Pillar, and with other pillars.
- Ten Gods: Converting the Hour Stem into a Ten God (e.g., Direct Wealth, Indirect Resource, Eating God) relative to the Day Master. This reveals the nature of the relationships represented.
- Palace of Children: The Hour Pillar is often considered the palace of offspring. If it clashes with the Day Pillar, it may suggest parent-child conflicts.
- Luck Cycles: The Hour Pillar is used to assess fortune after age 50.
Important Notes
- Accurate birth time is crucial: A small error can change the entire Hour Pillar.
- Rat hour debate: Some schools start the new day at 23:00, others at 00:00, which can affect the Day Stem and thus the Hour Pillar.
- Daylight Saving Time: If born during DST, convert to actual solar time.
- No absolute determinism: BaZi is a reference tool; personal effort and environment always matter.
Conclusion
The Hour Pillar completes the Four Pillars, offering insights into later life and children. Understanding it deepens appreciation of how the ancient sexagenary calendar system is applied to human destiny. Whether you believe in it or not, exploring BaZi objectively can provide interesting perspectives.
