Day pillar 丙子 (Byeongja): Yang Fire on the Rat
The 丙子 pillar, Byeongja, brings together two opposites: a frank sun and winter water at midnight. The image is of light reflected on a dark lake, all the more beautiful because the water holds it and sends it back.
1. The image
Yang Fire is the sun, generous, visible to all. The Rat is a Water branch, in the depths of winter and of the night. Water masters fire: in this image, the light meets a limit that disciplines it rather than putting it out, which we call here the framework. The hidden stem 癸, a single fine water, makes this demand clear and constant. The nayin 澗下水, “Water of the Ravine Stream”, adds a trickle of pure water running at the bottom of a gorge, sheltered, without a sound.
2. Your birth element: Yang Fire
Yang Fire is the sun: a warmth everyone can see, lighting up everyone at once. You may recognize yourself in this generous drive, this way of walking into a room and getting the conversation going. The flip side: giving a lot, very fast, then running short of reserves for yourself.

3. What it rests on: the Rat
The Rat is a Water branch, the branch of midwinter, around December, when the nights are longest. It hides only one stem, 癸, Yin Water: a pure, concentrated seat. In this image, the base of the pillar is lively, discreet, turned toward listening and reflection.
The frame is the element that masters the stem, with the opposite polarity: a measured constraint that structures rather than crushes. On this seat, the tradition sees a sense of responsibility, of keeping your word, of honoring commitments. The flip side: worrying too much about the image you give. The lever: check that the rule still serves you.
4. In daily life
You may have a natural radiance and, at the same time, a keen sense of what is and isn’t done. You liven up the dinner but think about tidying up afterwards; you dare an idea in a meeting while respecting everyone’s role. The flip side: the night sometimes weighs on the sun. You can hold yourself back for fear of how others see you, or feel rules as a lack of freedom you don’t talk to anyone about.
5. Up close, as a couple
In your intimate life, this image combines warmth and seriousness: you can be committed, true to your word, keen for the relationship to last. The flip side is feeling judged by the other person more than they actually judge you, or keeping your light for the outside world and your tiredness for home. Sharing a light-hearted moment, with nothing at stake, rebalances the reflection.
6. The lever
The lever: turning the limit into a mirror. The water doesn’t put you out; it reflects your image back to you. When a constraint annoys you, a rule, an expectation, a schedule, ask what it lets you see about yourself: a desire, a value, a tiredness. The rule then becomes information rather than a weight. Which constraint in your week could tell you something useful about what you really want, if you looked at it differently?
7. The nayin: Water of the Ravine Stream
澗下水, Water of the Ravine Stream: clear water flowing between the rocks, out of sight. The image suggests purity, discretion, a fresh and lively inner life. The tradition sees it as a modest water that follows its course without a sound.
8. Why this pillar isn’t the whole story
This pillar is only one part of your chart. Saju counts eight signs, spread across the year, month, day and hour of birth. Thousands of people share this same day pillar, since it comes back every 60 days. What changes everything is the rest: the year and month set the scene, the hour adds its nuance, and the balance of the elements draws a chart that is yours alone.
The next 丙子 days
The calendar of days moves forward continuously: here are the next dates when this pillar comes back, for information only.
Frequently asked questions
Do Fire and Water clash in the 丙子 pillar?
They are in a relationship of mastery: the Rat’s Water controls the Fire of 丙. In Saju, this corresponds to “the framework” (正官), a structure rather than a conflict. How this relationship is lived depends on the balance of the rest of the chart.
Why do people talk about the 11 p.m. rule?
In many Saju schools, the day doesn’t start at midnight but at 11 p.m., at the beginning of the hour of the Rat. If you were born between 11 p.m. and midnight, your day pillar may therefore be the next day’s. Other schools keep midnight. Local solar time can also shift this boundary.
Are two people with the same day pillar alike?
They share the same basic image, but not the same chart. The year, month and hour pillars change the balance of the elements and the way the day expresses itself. Two people with the same pillar can therefore have very different temperaments, each in their own way.
