Day pillar 丁亥 (Jeonghae): Yin Fire on the Pig
Jeonghae is a lamp flame set at the edge of winter water. A small light, precise and tenacious, that shines all the brighter for the deep night around it. The Pig frames it without ever putting it out.
1. The image
In this image, Yin Fire, the fire of the candle or the star, stands above the Pig, a Yang Water branch at the start of winter. Water masters fire: tradition sees the framework in it, a rule that contains the flame rather than drowning it. The Pig also hides Wood (甲), which feeds the fire from within, and its main Water is in tune with the stem through a combination. The nayin is Rooftop Earth (屋上土): the shelter above the lamp.
2. Your birth element: Yin Fire
Yin Fire suggests the candle or the lamp: a close light that brightens whatever is right in front of it. In this image, you notice details, moods, what a message implies. This attention warms people. Its flip side: feeling everything up close and holding on for a long time to what has touched you.

3. What it rests on: the Pig
The Pig is a Water branch, the one that opens winter, around November. It hides 壬 Yang Water and 甲 Wood: a deep water already carrying a seed. In this image, the seat of the day is generous, open, turned toward rest, sharing and what quietly germinates.
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 be someone who sheds light without taking up all the room. In a group, you ask the question that moves things forward, then fall silent. You work well when the framework is clear: a schedule, a role, a promise made. You care about doing things properly. The flip side: you can rein in your intensity to stay proper, or wait to be allowed to shine. Some evenings, the flame draws in and you stop saying what you feel, for fear of being a bother.
5. Up close, as a couple
The Pig, in the spouse palace, evokes a gentle, deep, slightly secret intimacy. You may need a quiet home where your light has nothing to prove. The combination between your stem and the Pig’s Water speaks of an attraction to what gives you structure. The flip side is adjusting so much to the other person that you forget your own warmth. Here, being close also means keeping a corner of light for yourself.
6. The lever
Jeonghae’s flame doesn’t lack strength; sometimes it lacks permission. Your lever: give yourself permission instead of waiting for it. Pick a situation where you usually hold back your opinion, and say it, simply, once. The framework stays in place, but you take your place within it. Where in your life are you still waiting for someone to tell you that you’re allowed to speak?
7. The nayin: Rooftop Earth
屋上土, Rooftop Earth: the fired clay of the tiles covering a house. The image suggests shelter, home, the protection given to those who live beneath. The tradition associates it with an earth shaped by fire, useful and reassuring, turned toward others.
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 丁亥 days
The calendar of days moves forward continuously: here are the next dates when this pillar comes back, for information only.
Frequently asked questions
Is there a hidden combination in the Jeonghae (丁亥) pillar?
Yes. The day stem, Yin Fire (丁), and the main stem hidden in the Pig, Yang Water (壬), form one of the five stem combinations, 丁壬, associated with Wood. Tradition reads a close link in it between the person and their intimate life, to be interpreted with 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.
