What forms the Jeongchuk day pillar?
A day pillar is the stem and branch of the birth day, rather than the birth-year animal. Jeongchuk is combination 14 of the sixty-pillar cycle. The engine reports a Yin Fire Day Master, Jeong, above branch Chuk (Earth).
The illustration uses candles and lanterns for Jeong. Choose one task worth sustained care, while allowing yourself to put another aside.
The branch Chuk is Earth; its hidden stems are Gye · Sin · Gi, ending with the main stem Gi. The branch animal is Ox. This animal describes the day branch here, not automatically the person's birth-year sign.
| Field | Engine result and convention |
|---|---|
| Day Master | Jeong (丁) · Yin Fire |
| Day branch | Chuk (丑) · Earth · Ox |
| Nayin | Water in the Ravine (澗下水) |
| Hidden stems / main | Gye · Sin · Gi / Gi |
| Ten God | Eating God |
| Void | Sin·Yu |
| Twelve Sinsal | Hwagaesal (Canopy Star) |
What does Water in the Ravine mean, and how does its paired pillar differ?
Water in the Ravine (澗下水) is the traditional Nayin name shared with Byeongja. A Nayin image is a cultural metaphor, not an element count, a useful-element prescription or proof of a personality trait. Its element can differ from the Day Master's element without being an error.
The pair makes the distinction concrete: Jeongchuk has main hidden stem Gi and Eating God, while Byeongja has Gye and Direct Officer. Their branch positions are Hwagaesal (Canopy Star) and Jangseongsal (General Star). Sharing the name Water in the Ravine therefore does not give the two combinations the same structure or life story.
| Comparison | This pillar | Nayin pair |
|---|---|---|
| Day pillar | Jeongchuk | Byeongja |
| Polarity | Yin | Yang |
| Main hidden stem | Gi | Gye |
| Ten God | Eating God | Direct Officer |
| Void | Sin·Yu | Sin·Yu |
| Twelve Sinsal | Hwagaesal (Canopy Star) | Jangseongsal (General Star) |
Why is the main hidden stem classified as Eating God?
For Jeongchuk, the engine compares Day Master Jeong with main hidden stem Gi, producing Eating God. The surface elements are Fire and Earth; the Ten God calculation uses the hidden stem's element and polarity, not just the branch's surface label.
The Day Master produces this element, with matching polarity. Eating God can serve as a metaphor for repeatable work and expression.
This is the representative classification by the main hidden stem. Other hidden stems remain part of the chart; the month, hour and surrounding pillars can change the interpretation's emphasis.
A second comparison keeps the Day Master fixed: Jeongmyo also begins with Jeong, but its main hidden stem is Eul, its Ten God Indirect Resource, and its Nayin Fire in the Furnace. In this comparison the lower character, not the upper one, changes the result. Compare the actual fields before borrowing an interpretation from another pillar with the same stem.
When do the next Jeongchuk days occur?
Starting from 26 October 2026, these are the next three calendar days whose engine dayGZ() equals Jeongchuk. They repeat at 60-day intervals. A matching day is not a promise of a successful exam, contract or relationship, and does not require moving a real appointment.
| Calendar date (as of 2026-10-26) | Day pillar |
|---|---|
| 2026-10-30 · Fri | Jeongchuk (丁丑) |
| 2026-12-29 · Tue | Jeongchuk (丁丑) |
| 2027-02-27 · Sat | Jeongchuk (丁丑) |
A recurring day is a shared calendar label, not a private appointment with fortune. You can put it beside a journal entry and compare what actually happened, including observations that do not fit the interpretation. After the three dates listed here pass, check the calculator again for the next cycle; the article's reference date does not move automatically.
What does the Void pair Sin·Yu mean?
The engine's sixty-cycle table gives Sin·Yu for Jeongchuk. Gongmang, often called Void, identifies two unused branches in its ten-day group. A two-pillar Nayin pair and a ten-day group are different classifications.
Seeing either branch elsewhere in a chart does not erase a person, relationship or opportunity. Treat this as an auxiliary traditional idea, not a reason to cancel plans or spend money. Real circumstances take priority.
Why is this branch in the Hwagaesal (Canopy Star) position?
Here the reference is the day branch Chuk's own Three Harmony group, and the target is Chuk again. That produces Hwagaesal (Canopy Star). It is not a calculation from the birth-year branch and does not list every star in a full chart.
A storage branch is linked with concentration and consolidation. It does not diagnose loneliness; choose a balance between focus and contact that suits your life.
Can Jeongchuk alone determine personality, compatibility or work?
Jeongchuk is one pillar of a complete saju chart. A different birth month, hour, other pillars and long-term periods can change the context. These two characters cannot fix personality, marriage prospects or career, and MBTI uses a different basis rather than an interchangeable code.
Use interpretations as questions to compare with experience. They do not guarantee outcomes or support medical, legal or investment decisions. The linked concept guides explain the terms before any personal interpretation.
First confirm that a birth date is Gregorian or convert a known lunar date using the correct country's calendar. For a day pillar, year alone is insufficient. Time near the late-night day boundary also requires a stated convention. The web calculator offers optional corrections; use the same options when comparing two results rather than assuming different displays prove an error.

Frequently asked questions
What is the Jeongchuk day pillar?
It is 丁丑, combination 14 of sixty. Its Nayin is Water in the Ravine; its Void branches are Sin·Yu.
What is Jeongchuk's day-branch Ten God?
Using main hidden stem Gi within Gye · Sin · Gi, the engine computes Eating God relative to Jeong. This is the main-stem classification.
When is the next Jeongchuk day?
As of 2026-10-26: 2026-10-30, 2026-12-29, 2027-02-27. These calendar days recur every 60 days and do not guarantee a good outcome.
Is Hwagaesal (Canopy Star) the only star in a Jeongchuk chart?
No. Hwagaesal (Canopy Star) here describes the day branch's position within its own Three Harmony group. A full chart and another reference branch can give other classifications.
