Day stem - your temperament

The day stem 乙 is Wood, symbolised by a flowering vine.

Gentle and adaptable, blending in easily and thriving even in tough conditions.

Tends to be indecisive when a firm choice is needed, and puts off asserting itself.

A yin stem, so the energy gathers inward. Fine-grained and durable, though you can stall on decisions and carry the strain silently.

Day branch - the ground you sit on

The day branch 亥 is Water, the Pig branch.

A wide-flowing seat. You take people in without picking and choosing - and get swept along just as easily.

Inside 亥 sit the hidden stems 戊(residual 7), 甲(middle 7), 壬(main 16), of which 壬 is the main one. Beyond the visible Water, these stems work from within, which is why the same branch reads differently from person to person.

The Ten God in your day branch - reading the spouse seat

Seen from the day stem 乙, the branch's main stem 壬 is Direct Resource. The day branch is the seat closest to a partner and the ground you stand on daily, so the Ten God sitting there shapes the texture of everyday life.

The supporting, studying force sits underneath. Elders and teachers tend to help you, and you do well where learning and credentials accumulate. Stay too long in that comfort and leaning becomes a habit - practise standing alone.

How stem and branch meet

The branch generates the stem, so your foundation supports you. You hold steady instead of swinging wildly.

Twelve stages - your energy in this seat

The day stem 乙 meets the branch 亥 at the Death stage.

The stage where motion stops and thought deepens. Strong in study or craft that goes deep into one thing, though you linger a long time before deciding.

Void branches - the two empty seats

The 乙亥 pillar belongs to the 甲戌 decade, and the branches left empty in it are 申 and 酉.

A void branch is less a bad omen than a marker meaning your heart does not fully settle here. Years ruled by those branches tend not to fill up as planned - but attachment thins out too, which can feel like relief, and it often turns into a strength in fields that work with emptiness: religion, scholarship, art.

Sound element (Napeum)

The sound element of 乙亥 is Fire on the Mountaintop (山頭火) - an old name given to the pair itself, separate from the elements of the stem and branch.

A Fire sound-element, so the grain is one of lighting up. It shines where things are shown, announced and warmed - the trick is managing the fuel so it does not burn out.

Branches that fit, branches that clash

The branch that pairs with 亥 in six-harmony is 寅, and the branches forming its triad are 卯, 未. Against that, 巳 clashes with it and shakes the seat.

Years and people whose branch harmonises with yours tend to run smoothly and feel easy. The clashing side shakes the seat instead - moves, partings, turning points - which is not simply bad: it is also the force that pushes out what had gone stagnant.

Work that suits you

By the element of the day stem (Wood): fields that draw on growth and planning, like education, planning/strategy, design, timber & landscaping, or publishing

The branch's element (Water) is layered on top: fields where you read trends and operate broadly, like trade, distribution/logistics, communications, or research Choose work where the two grains overlap - that is where you last.

Day stems that match well

Compatibility is decided by the relationship between day stems, so the six day pillars sharing a stem score the same.

Frequently asked

What is the 乙亥 (eul hae) day pillar like?

a flowering vine sitting on the Pig branch - The Flexible Harmonizer. It sets the temperament of the stem 乙 on the ground of 亥, so you live at the Death stage standing on Direct Resource.

Can the day pillar alone tell you everything about someone?

No. The day pillar is two of the eight characters; the other six - year, month and hour pillars - together with the luck cycles make two people of the same day pillar read very differently. The month branch, which sets the season of birth, weighs especially heavily, so treat a day-pillar reading as a starting point.

What are the void branches of the 乙亥 (eul hae) day pillar?

sin and yu. If either sits in another pillar of the chart, that pillar is read as void. Voids only mean something in the context of the whole chart, so the day pillar alone does not make them good or bad.

Which day pillars go well with the 乙亥 (eul hae) day pillar?

By the relationship between day stems, byeong, im sit well with you. By branch, 寅 forms a six-harmony and feels easy, while 巳 clashes. Real compatibility, of course, comes from comparing both charts in full.
