Black Goat (Gui Wei): Personality and Matches
Hongsimdang Editorial Team · Last updated
Black Goat (Gui Wei) is the day pillar where rain and mist that seep in quietly (癸) rests on earth at the end of summer (未). In short, it is polished within responsibility and structure and builds trust a little at a time.
What decides the Black Goat: day stem and day branch
Your day pillar is the stem and branch of the day you were born: the upper character is the day stem and the lower one is the day branch. For Black Goat (Gui Wei), the day stem is 癸 (Yin Water) and the day branch is 未 (Goat). The “Black” in the name is the color of the day stem’s element, and “Goat” is the zodiac animal of the day branch. Both are Hongsimdang’s own labels.
The day stem 癸 is likened to rain and mist that seep in quietly. You say little and keep watching, and by the time you speak you have usually reached the heart of the matter. The day branch 未 is earth at the end of summer. The Goat is popularly pictured as caring, warm-hearted and gentle on the outside but stubborn within, but that is the folk image of the zodiac. The actual reading comes from the element relationship and life stage that follow.
Read as elements, your stem and branch form an authority pair, in which the branch presses on the stem. The branch’s element presses on your stem, so you tend to be polished within the frame of rules, responsibility and other people’s expectations. The branch 未 also holds the hidden stems 丁, 乙, 己, which lay another side beneath the one that shows.
Seen from your day stem 癸, the day branch 未 sits at the Tomb (Mu) stage of the twelve life stages. It is the stage of storing things away, which brings steadiness and a caution about showing what you think.
How the Black Goat shows up at work
Your strength gets polished in settings with rules, roles and deadlines. A strong sense of responsibility means people hand you a lot, but when what you carry piles up, fatigue arrives all at once, so line up someone to hand things to early.
You earn trust in coordinating, mentoring and care roles, and you fit best supporting the whole from behind the scenes. Until you feel sure, you can hide for too long, or keep putting off the first step.
After you have put up with something for a while, your stubbornness comes out and you suddenly stop moving.
State your limit before taking something on, and decide where your help stops being a strain.
How the Black Goat shows up in relationships and love
You are aware of your partner’s standards and of how others see you, and you work to stay proper. Your own wishes tend to get pushed back, so letting small true feelings out in daily life makes the relationship easier.
You put yourself in the other person’s shoes so readily that you keep enduring, and out of loyalty you sometimes cannot say no.
Choose someone who asks for help without hesitating and thanks you properly for the effort.
How the Black Goat handles money
Fixed income and a solid system keep you stable, and discipline works as your defense. In tense periods unexpected costs tend to pile up, so keep a reserve in a separate account from the start.
You save quietly, bit by bit, and gather information before you act, so big mistakes are rare. The cost is that you sometimes let a good opening pass.
Much of your money goes to people close to you, and when you are asked you cannot refuse, so outlays grow. Deciding a limit on lending in advance gives you peace of mind.
Day branches that harmonize with the Black Goat and ones that clash
The day branch of Black Goat (Gui Wei) is 未 (Goat). Which day branch the other person has decides the relation between your two branches, as shown below. A day branch that is not listed has no direct harmony or clash with yours.
| Their day branch | Relation between branches | How it reads |
|---|---|---|
| Rabbit (卯) | Triple Harmony partner | moves in the same direction, and the group is complete once a third branch joins |
| Horse (午) | Six Harmony | pulls together and fills in |
| Goat (未) | Same day branch | like with like |
| Pig (亥) | Triple Harmony partner | moves in the same direction, and the group is complete once a third branch joins |
| Rat (子) | Harm, Resentment / Ghost Gate | small misunderstandings pile up; attracts yet irritates |
| Ox (丑) | Clash, Punishment | head-on opposition; rubs, so friction is likely |
| Dog (戌) | Punishment, Break | rubs, so friction is likely; cracks are likely |
Harmony, Clash, Punishment, Harm, Break and Resentment are relations fixed mechanically by the pair of branches. They say nothing about anyone’s character being better or worse.
2027 (Ding Wei year) and the Black Goat
2027 is a Ding Wei year. The year’s stem and branch change over at the start of spring, around February 4, 2027. The Ding of 2027 is the money and openings your day stem steers. The amounts and range that move tend to widen, and your eye for managing what comes in and goes out is tested. The year branch Wei is the same as your day branch, so its character stacks up and shows more strongly, with strengths and habits both amplified.
What the day pillar alone cannot tell you
The day pillar is one of the four pillars of a chart. The year, month and hour pillars, the ten-year luck cycles, and Zi Wei Dou Shu and Western astrology readings are not included on this page. Two people with the same Black Goat can show it differently depending on their other pillars, and your day pillar alone does not settle personality or fate.

Frequently asked questions
How do I find out whether I am a Black Goat?
The day of Black Goat (Gui Wei) comes around once every 60 days, and people born on a 癸未 day belong to this type. Enter your birth date on the day pillar type index to check.
Why am I a Black Goat if my birth-year animal is not the Goat?
The birth-year animal comes from the year branch, while the Goat in Black Goat comes from the day branch 未. They are two separate calculations. Even if your birth year belongs to another animal, a day branch of 未 makes your day pillar a Goat.
Which types match the Black Goat?
Looking only at day branches, the Six Harmony partner of 未 is the Horse (午), and the clash comes from the Ox (丑). That is one narrow view. How well two people fit depends on all four pillars and on how they treat each other.
