Of the eight characters in your chart, one is the seat of your closest relationship: the Earthly Branch directly beneath your Day Master. This is the Spouse Palace (日支), and it's the single most direct signal BaZi gives about your partner and your marriage. Here's what it is, what it hints about who you attract, and how practitioners actually read it.
Your Day Pillar is the center of your chart. The stem on top is your Day Master — you. The Earthly Branch directly beneath it is your Spouse Palace — the seat of your husband or wife. The logic is positional and elegant: your partner sits closest to you in the chart, literally underneath your own character. No other pillar sits that close.
This is why BaZi reads marriage from the Day Pillar and treats birth-year animal matching as noise — the year branch is three pillars away from the Spouse Palace.
The element and character sitting in your Spouse Palace describes the kind of partner you tend to attract and feel at home with — read through the branch's element and the Ten God it represents relative to your Day Master. Broadly:
An important caution: the Spouse Palace describes a tendency, not a person's identity, and it's only one factor. The heaviest compatibility question is still whether a specific partner's chart supplies your useful element — the Spouse Palace refines that read, it doesn't override it.
When two charts meet, practitioners compare the two Spouse Palaces — the two Day Branches — for four interactions:
| Interaction | Reads as |
|---|---|
| Six Harmony (六合) | Smooth, cooperative, easy day-to-day |
| Six Clash (六冲) | Friction, movement, change — not doom |
| Harm (害) | Quiet erosion, resentment that doesn't announce itself |
| Punishment (刑) | Entanglement, obligation, everyone technically right and still suffering |
A clash between Spouse Palaces is the one people panic about, and it shouldn't be a verdict — it shakes something loose, and if what's released is an element you needed, it helps. What a marriage struggles to survive is a clash sitting on top of elemental incompatibility, not a clash alone.
The Spouse Palace isn't static. A Luck Pillar or annual year whose branch combines with or clashes your Day Branch "activates" the marriage area — these are the periods practitioners flag as marriage windows or as years of change in an existing relationship. In 2026 (丙午, Yang Fire Horse), the Horse branch 午 clashes 子, so charts with a Rat Day Branch have their Spouse Palace struck this year: movement in the marriage area, for better or otherwise.
The Spouse Palace is a strong signal, not a portrait. It tells you the shape of partner you gravitate toward and how your marriage area behaves under a clash or a combination. It doesn't name a person, guarantee an outcome, or override the bigger question of elemental supply. Use it as the most direct single clue, then read it inside the whole chart.
Ming computes your Four Pillars deterministically — the exact stems and branches for your birth moment — then explains them in plain English. No signup, no guessed pillars.

It's the seat of your closest partner and the single most direct signal BaZi gives about your husband or wife and your marriage, which is why marriage is read from the Day Pillar rather than the birth-year animal.
The element and Ten God in your Spouse Palace hint at the kind of partner you attract and feel at home with — nourishing, structuring, or led by you, depending on how the branch relates to your Day Master. It's a tendency, not a person's identity, and it works alongside the bigger question of whether their chart supplies your useful element.
A Six Clash (六冲) on the Day Branch means friction, movement, and change in the marriage area — not doom. It can even help if it releases an element your chart needed. Many long marriages contain one. The harder pattern is a clash sitting on top of elemental incompatibility, not a clash by itself.
Practitioners compare the two Day Branches for four interactions: harmony (smooth), clash (friction and change), harm (quiet erosion), and punishment (entanglement). This is one of the heaviest compatibility layers, second to whether each chart supplies the other's useful element.
