Day pillar 乙丑 (Eulchuk): Yin Wood on the Ox
With 乙丑, Eulchuk, the scene changes: a supple plant set on hard, damp winter earth. In this image, life isn’t showing yet, but it’s already working the soil, root after root, with stubborn patience.
1. The image
Yin Wood is the vine, the stem that finds a way around. The Ox is cold Earth at the end of winter. Wood masters earth: its roots work it, turn it over, organise it, which we call here mobile achievement. Hidden in the soil are 己, 癸 and 辛: loose earth, a little water, and a hint of metal reminding you that not everything gives way. The nayin 海中金, “Metal at the Bottom of the Sea”, shared with 甲子, speaks of a patient treasure kept beneath the surface.
2. Your birth element: Yin Wood
Yin Wood suggests the vine, the grass, the plant that finds its way between the stones. In this image, you move forward through suppleness: you observe, you adapt, you lean on your connections. This finesse opens doors for you. Its flip side: adjusting so well to others that your own course goes blurry.

3. What it rests on: the Ox
The Ox is an Earth branch, the branch of late winter, around January. It hides three stems: 己 Earth, 癸 Water and 辛 Metal. The tradition sees it as a store, a cold earth that keeps things and lets them ripen. In this image, the seat of the day is patient, solid, made to last.
Mobile achievement is the element the stem masters, with the same polarity: a material you shape freely. The tradition associates it with a sense of opportunity, generosity, ease with people and with varied projects. The flip side: scattering yourself across several wishes without seeing one through. The lever: choose what truly deserves your follow-through.
4. In daily life
At work, you may be the person who moves a complicated file forward without fuss, finding a small way through every day. You tidy up, you follow up, you adjust a schedule others had given up on. This quiet tenacity gets concrete results. The flip side: by carrying everything at arm’s length, you can wear yourself out on ground that’s too hard, or keep to yourself a tiredness nobody sees, because you don’t complain.
5. Up close, as a couple
At home, this image loves what is built slowly: habits, a well-kept place, simple rituals. You show your attachment by organising, by anticipating the other person’s needs. The flip side is confusing care with control, or staying silent about what weighs on you until the day it all comes out at once. Mentioning a small discomfort early protects the gentleness of the bond.
6. The lever
The lever: choosing where to put down your roots. Yin Wood can get through hard ground, but not all of it at once. Look at your current commitments as plots of land and spot the one that asks a lot of you and gives back little life. Letting it go, or simply scaling it down, frees up strength for the rest. Of everything you’re holding right now, which plot could you leave fallow for a month?
7. The nayin: Metal at the Bottom of the Sea
海中金, Metal at the Bottom of the Sea: a precious metal still hidden beneath the waters. The tradition sees in it a value that doesn’t show right away. The image suggests an inner richness, patience, qualities that reveal themselves with time and trust.
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 乙丑 days
The calendar of days moves forward continuously: here are the next dates when this pillar comes back, for information only.
Frequently asked questions
Why does 乙丑 share its nayin with 甲子?
In the nayin system (納音), the sixty pillars are grouped in consecutive pairs, and each pair receives the same image. 甲子 and 乙丑 form the first pair, “Metal at the Bottom of the Sea”. This image adds to the reading; it doesn’t replace the element of the stem.
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.
