Day pillar 甲申 (Gapsin): Yang Wood on the Monkey
Gapsin is a tall tree planted on ground of rock and metal. It grows under constant demands, and it is often those very demands that invite it to stand up straighter rather than bend under the weight.
1. The image
In this image, Yang Wood stands above the Monkey, a Yang Metal branch at the very start of autumn. Metal cuts wood: tradition reads pressure in it, a framework that doesn’t let things grow any old way. But the Monkey also hides Water (壬), and water feeds the tree. The constraint then turns into a resource when you take the time to absorb it. This pillar’s nayin is Spring Water (泉中水): water welling up between stones, quiet and clear.
2. Your birth element: Yang Wood
Yang Wood is the image of the tall tree growing straight toward the light. You may recognize yourself in this need to have a direction and to grow at your own pace. Once you’re on your way, you hold your line, even when others hesitate. The flip side: giving way costs you, even when a small detour would be simpler.

3. What it rests on: the Monkey
The Monkey is a Metal branch, the one that opens autumn, around August. It hides 庚 Yang Metal, 壬 Water and 戊 Earth: a material that hardens and a water that begins to flow. In this image, the seat of the day is nimble, inventive, quick to find solutions.
Pressure is the element that masters the stem, with the same polarity: a direct force, without detours. On this seat, the tradition sees courage, resilience, an ability to act when everything is tense. The flip side: living on high alert, demanding a lot of yourself. The lever: give yourself moments when there is nothing to prove.
4. In daily life
You may recognise yourself in someone who works better with a deadline than with a blank page. A colleague throws you a challenge in a meeting, and instead of bristling, you come back the next day with a stronger version. You know how to stand tall when you’re put to the test. The flip side: you can end up believing nothing counts without pressure, and set yourself exams nobody asked you to sit. On evenings when everything is calm, you sometimes look for the next difficulty instead of catching your breath.
5. Up close, as a couple
Up close, the Monkey is a lively, curious branch that keeps moving. You may enjoy a relationship that stimulates you, where people say things to each other and help each other grow a little. The risk is confusing high standards with attention: picking up on every detail of daily life, the dishes put away wrong, the message that’s too short. In this image, closeness is also nourished by moments when nobody is assessing anybody.
6. The lever
Gapsin’s lever lies in the Monkey’s hidden water: turning pressure into a resource rather than a fight. In practice, when a demand lands, take ten minutes to note what it teaches you before deciding how to respond. You keep your uprightness, but you choose what you let in. This week, which demand do you accept by reflex when it no longer brings you anything?
7. The nayin: Spring Water
泉中水, Spring Water: water that wells up from the earth, fresh and inexhaustible. The image suggests renewal, clarity, an inner resource that always returns. The tradition sees it as a precious water that nourishes without running dry when it is respected.
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 甲申 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 the Gapsin (甲申) pillar a difficult pillar?
Not necessarily. The Monkey’s Metal puts pressure on the day’s Wood, which tradition calls 七殺. But the Monkey also contains Water (壬), which feeds the Wood: this chain of metal, water, wood is often read as a constraint that can become support. The rest of the chart matters a great deal.
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.
