Byeongja Day Pillar (丙子)
— Water in the Ravine, Flowing Through the Valley
The Byeongja day pillar has Byeong (丙), the midday sun, sitting on Ja (子), the deep water of midwinter. Its Nayin is Water in the Ravine — water flowing through a mountain valley. Gongmang: Sin and Yu. Sinsal position: Jangseongsal.
People whose birth day's stem-branch pair is Byeongja are said to have a Byeongja day pillar. It's the 13th of the sixty combinations of the sixty Gapja. The day pillar is the seat of “me” in Saju, so starting here makes the whole birth chart easier to read. Let's go through its structure one piece at a time.

What kind of combination is Byeongja?
It's a picture of the midday sun sitting on the deep water of midwinter. Byeong Fire (丙火) is the fire that floats in the sky and shines on all things. It's said to find it hard to hide its presence, lifting the mood with optimistic energy.
Ja Water (子水) is where a seed prepares to sprout under water. It's considered a position full of plans and deliberation before anything shows. In Five Elements terms, the Byeong Day Master is Fire and the Ja day branch is Water — the seat keeps you on your toes. If the very idea of a day pillar is new to you, it's a good idea to read that first.

What does the Nayin element Water in the Ravine mean?
It means water flowing through a mountain valley — water running between the ravine walls. Though not as wide as a great river, it flows without rest, and when it meets a rock it keeps going, even if it has to go around. It's clear, cold water, so it's sometimes interpreted as clear-headed judgment.
The pair that shares Water in the Ravine is the Jeongchuk day pillar. Of the two, Byeongja is on the yang-stem side, so it's seen as spreading the same image outward.
How do the Byeong Day Master and Ja day branch relate?
Inside the day branch are hidden Heavenly Stems called hidden stems. Ja's hidden stems are Im and Gye, and its representative character (main hidden stem) is Gye (癸). Read through the eyes of the Byeong Day Master, this becomes Direct Officer.
It sits on an energy of order and norms. With a wish to conduct oneself properly running underneath, it has long been interpreted as a position of trust and honor. Diligence in keeping to one's duties is considered its strength. You can see all ten Ten Gods, from Companion to Direct Resource, in The Ten Gods: the complete guide.
When is the next Byeongja day?
Each day on the calendar carries a stem-branch pair too. We calculated when the next Byeongja day falls with Mutal Unnie's Saju engine. The cycle is 60 days.

These are the days when a person with a Byeongja day pillar has their own stem-branch pair come around again. Rather than sorting them into good or bad, we suggest using them as days to check your own pace. The idea of iljin continues in the iljin story.
What does Gongmang Sin and Yu mean?
Gongmang is set by the group (decade) your day pillar belongs to. The Byeongja day pillar belongs to the Gapsul decade, so its Gongmang is Sin and Yu. The empty characters are Sin (申) and Yu (酉) — both Metal energy. Days carrying these characters are interpreted as days to refine the process rather than push for results.
Gongmang isn't something to fear; it's closer to a marker telling you where to ease off. How Gongmang works across the whole birth chart is described in detail in Gongmang explained.
What does the Jangseongsal position mean?
Ja is the peak position of the Sin-Ja-Jin Water group (水局) in the Three Harmony. So in the Twelve Sinsal, the Byeongja day branch is read as Jangseongsal.
Jangseongsal is the position of the one who carries the flag. A peak-position character sits on the day branch, so it's interpreted as an energy that comes alive when leading rather than following others. The full picture of the twelve sinsal is in The Twelve Sinsal: the complete guide.
Is the day pillar all I need to look at?
The day pillar is two of eight characters. Even with the same Byeongja day pillar, a different birth season (month branch) and time make an entirely different Saju. A Byeong (丙) born in midwinter and a Byeong (丙) born in midsummer differ from the very first thing they need. So this article introduces the nature of the Byeongja combination; it isn't a personal Saju reading. If you're curious about your whole birth chart, start with How to read Saju: the complete guide.
