일주 · Day pillar
Yang Metal over the Rat
庚子 · 경자일주
One of the six Forged Blade days
Your day pillar is the day you were born, written as two characters: Metal on top for you, and the Rat underneath for what you’re sitting on. Of the four pillars in a Saju chart, this is the one that stands for you and the person next to you, which is why a reader looks at it first. There are sixty in all, and this is one of them.
Frost forming on cold iron
You’re Yang Metal over the Rat — steel sitting in cold water. You’re sharp, articulate and cool-headed, with a mind that cuts straight to the point.
People find you either brilliant or intimidating, and you rarely try to settle which.
The Saju bit · the traditional reasoning
The day you were born gives you Yang Metal over the Rat, written 庚子 and called 경자일주 in Korean. The top half is the Day Master, the character that stands for you, and it reads as raw metal: strong and sharp, just waiting for something to give it shape.
A razor mind with a detached streak
In practice you’re witty, persuasive and a natural contrarian, with little patience for received wisdom and a tendency to watch life from slightly outside it.
The Saju bit · the traditional reasoning
You’re sitting on the Hurting Officer star , the star of a sharp tongue and a gift for words, at the Death stage , which isn’t literal: it’s where energy goes still and turns inward. You have a quick, critical mind and a way with words, paired with a cool, watchful detachment.
You sit on what you give out
Underneath your Day Master is the part of a chart that expresses, makes and looks after. Read for home life, that’s someone whose domestic life runs on doing: cooking for people, fixing things, keeping the household going through effort rather than announcements.
It also points to a partner you end up caring for in practical ways. Watch for pouring everything outward and leaving nothing for yourself — this seat empties faster than it refills.
This pillar sits at a still stage of the cycle. Nothing to do with dying: it reads as energy turned inward, which shows up as depth, patience and a habit of thinking a thing through before touching it.
The Saju bit · the traditional reasoning
The seat is the Self-expression star , read from the main hidden stem of the Rat, and the life stage is 사.
Metal sitting on Water
Metal sitting on Water is always pouring itself out, because Metal feeds Water. You’re expressive and productive and you make things happen around you, and you’ll run yourself flat if nobody tells you to stop.
The Rat is a Water animal, which is where that comes from. It’s the same for every Yang Metal over the Rat, whatever else is in the chart.
Is this you?
Your day pillar comes from your exact date of birth, and nobody can work it out in their head. Put your birthday in and we’ll tell you which of the sixty you are, free, along with the rest of your chart: your elements, what you’re missing, and the part of you people notice first.
