Jia-Yin Day Pillar: Jia Wood over Yin Wood, Spouse Palace Friend
What are Jia-Yin people like? With Jia Wood as your Day Master, you are like a great tree growing toward the sky, carrying a stubborn streak of integrity deep in your bones. Your day branch holds Friend, so you are strong-minded, fair-minded and like to rely on yourself. In our sample of 280 Jia-Yin charts, 24.3% are strong and 35.0% weak, so strength depends on the birth month. Below: personality first, then love and how the pillar reads for women and men.
The day pillar is the closest of the four to you: the stem is you (the Day Master) and the branch is your spouse palace. The Jia-Yin pillar is therefore about the relationship between "Jia Wood the person" and "Yin the partner".

What Jia-Yin people are like
The Day Master Jia Wood sets the base tone: With Jia Wood as your Day Master, you are like a great tree growing toward the sky, carrying a stubborn streak of integrity deep in your bones. You live by your principles and take your promises seriously; when you tell someone you will do something, you hold it in your heart, and that is exactly why friends and colleagues find you so easy to trust. You were born with a natural touch of leadership, and when a moment calls for someone to step up, you are usually the first to raise your hand.
The day branch Yin has Friend as its main qi, and that is the layer Jia-Yin adds on top of the Day Master: Sitting on the Friend star makes for a clear sense of self and a pace of one's own; these people dislike being managed, care about fairness and face, and want partnerships to be equal. The strength is independence and a willingness to carry the load. Watch for stubbornness and the urge to win: when opinions differ, a step back often gets further.
Women and men: traditionally a woman's chart reads the husband star (the Officers) and a man's the wife star (Wealth). For a Jia-Yin woman, the husband star (the Officers) is not in the spouse palace, so look to the other pillars and the luck cycles; for a Jia-Yin man, the wife star Indirect Wealth is hidden in the spouse palace as its residual qi, so the bond needs time and care to surface. This only describes what tends to show up in relationships; see "The spouse star of Jia-Yin for men and women" below.
Personality is read from the whole chart; the day pillar is only its core. Two people with the same pillar can come across very differently once the month and the other pillars are added.

What is the structure of Jia-Yin?
Jia-Yin is the stem Jia over the branch Yin. Jia is Yang Wood and is your Day Master, standing for you; Yin is Wood and sits in the day branch, which is the spouse palace. The relation between the two therefore says two things at once: the grain of the person, and their default position inside an intimate relationship.
Hidden stems and Ten Gods: where the real weight sits
Each branch holds stems that are not written on the face of the chart, yet they decide how much each Ten God actually weighs. Yin holds 甲, 丙, 戊, which to the Day Master Jia Wood are:
The main qi carries the most weight, so the spouse palace of Jia-Yin mainly shows the face of Friend; the middle and residual stems are undertones that surface when a Luck Pillar or annual pillar stirs them.
How the stem and branch of Jia-Yin relate: same element
| Stem | Jia (Wood) |
|---|---|
| Main hidden stem of the branch | Jia (Wood) |
| Stem–branch relation | same element |
| Life Stage on its own branch | Taking Office |
| Root | main stem Jia: deep root |
The stem and the branch share the element Wood, which classical texts call "stem and branch of one breath". The Day Master sits right on its own root: steady, self-directed and not much in need of outside backing — but also slower to take advice. The spouse palace holds a peer star (Friend or Rob Wealth), so a partner can feel like a teammate and a rival at once; learning to yield helps.
Jia sitting on Yin: the "Taking Office" stage and the root
Taking Office, also called "establishing salary", is where the Day Master draws its own stipend: an adult starting a post, self-reliant and used to living by its own skill.
The Life Stages describe the state of momentum; this site judges a strong or weak Day Master by hidden-stem roots, not by the stages. See the full cycle of every stem on Twelve Life Stages.
From our engine: how strong Jia-Yin Day Masters tend to be
| Sample | 280 charts (one per day, 1960–2005; 16,802 in all) |
|---|---|
| Strong / balanced / weak | 24.3% / 40.7% / 35% |
| Average strong share, six Jia Wood pillars | 17%; Jia-Yin runs 7.3 points higher — the Yin branch clearly props the Day Master up |
| Most common first useful element | Water 58.2%, Fire 31.8% |
The day pillar is one pillar of four; a person’s strength still depends on the month and the whole chart. These figures show which way sitting on Yin pushes the Day Master. Method on Strong and Weak Day Masters.
Spouse palace in Yin: partner tendencies and how to get on
The partner：The partner is driven and ambitious, restless, with a lot going on outside the home. Yin is Yang Wood: growing upward is its nature, and they need a stage of their own, not only the household.
Where to put the effort：Accept the outward-facing side; insisting on constant closeness costs you both. In exchange, turn "home by when" into a clear agreement. They respect rules, and they pull further away from emotional pressure.
Worth saying plainly: the spouse palace describes a tendency, not who a person is bound to meet. It reads more like a map of the routes you take easily inside a relationship; knowing it saves a few wrong turns.
The spouse star of Jia-Yin for men and women
Traditionally a man’s wife star is Wealth and a woman’s husband star is Officer or Seven Killings; the question is whether that star sits inside the spouse palace (the day branch). For Jia-Yin:
| Place in Yin | Reading | |
|---|---|---|
| Male chart (wife star: Wealth) | residual stem, Indirect Wealth | the wife star Indirect Wealth is hidden in the residual stem of Yin: present but not prominent, so the bond tends to surface with time and care. |
| Female chart (husband star: Officer) | none | none of the hidden stems of Yin is an Officer star; the spouse palace holds Friend instead. Look to the other pillars and to when luck cycles and years bring an Officer star in. |
Many modern readers look at the spouse palace as a whole regardless of gender; the spouse star is one angle and should be read with the full chart.
Years that touch the Yin spouse palace, 2026–2037
The day branch is the spouse palace. When a year’s branch clashes, combines, punishes or harms it, matters of love and home are more easily stirred. The next twelve years:
| Clash | 2028 Wu-Shen |
|---|---|
| Six Harmony | 2031 Xin-Hai |
| Three Harmony | 2026 Bing-Wu, 2030 Geng-Xu |
| Punishment | 2028 Wu-Shen, 2037 Ding-Si |
| Harm | 2037 Ding-Si |
Heaven strikes, earth clashes: in 2040 (Geng-Shen) the year stem Geng attacks the Day Master Jia while the branch Shen clashes Yin — a once-in-sixty-years year of upheaval for this pillar.
Hidden echo (fu yin): 2034 is a Jia-Yin year again, identical to the day pillar; classical texts read it as repetition and old matters returning.
A year is only a trigger; good or bad depends on the luck cycle and the whole chart, so no single year decides anything. Zodiac-by-zodiac clashes are on Tai Sui.
Special structures in Jia-Yin
Day Virtue
The classical view：Classically called Day Virtue: kind by nature and thick in good fortune, disliking clashes, punishments, breaks and harms.
In plain terms：This type is generous and disinclined to fight, leaning towards giving ground, which over time accumulates goodwill and opportunity. People hand them things to look after precisely because of that steadiness.
Proportion：Being easy to deal with invites being taken advantage of. Keep the generosity for people who merit it and hold the boundaries that matter. That is not turning hard; it is letting the goodwill last.
Na Yin: Great Stream Water
Great Stream Water: fierce waves beating the bank, breakers rising to the sky.
A rushing great stream, waves striking the bank and surging skyward, flowing with force. Full of drive and brisk by nature, bold to charge ahead; amid the rapids, it should keep a measure of calm.
Each Na Yin is shared by two pillars: Jia-Yin shares Great Stream Water with Yi-Mao. It is a supporting layer of imagery, useful for overall flavor, but it does not override the main line set by the Day Master and the spouse palace.
Void branches: Zi, Chou
Jia-Yin belongs to the Jia-Yin decade, which never reaches the branches Zi, Chou; these are its void branches. Whatever a voided pillar stands for tends to be "present but not solid": not absent, but hard to hold, or late in arriving. In practice it matters which pillar is voided and whether it is clashed or combined; the fact alone settles nothing.
