BaZi compatibility: how two four-pillar charts fit

BaZi compatibility asks one direct question: does this person supply what you’re short of, or add more of what you already have too much of? Two charts, each with a day master and an element balance, are read against each other. Where one feeds the other, the pair flows. Where one controls the other, there’s friction to name and manage. Neither is a verdict on the relationship. Both are things you can see coming.

What is read

The two day masters

Every pairing of the five elements has a relation: same, feeding, fed by, controlling, controlled by. Wood with water is wood fed; wood with metal is wood controlled; wood with wood is peers. The relation between two day masters sets the basic temper of the pair: who tends to give, who tends to take, and where it rubs.

What each chart is short of

This is where compatibility gets useful. If you’re a weak fire day master short of wood, a partner whose chart is rich in wood feeds you, and you feel it as ease. If their chart is rich in water, the element that controls fire, you feel it as being dampened. The reading says so plainly and tells you what to do when it happens.

The branches

The earthly branches of the two charts meet too: some combine, some clash, some harm. A day-branch clash between two people is a known pattern of recurring arguments; a combination is a known ease. The reading names the pattern instead of predicting the fight.

What today does to the pair

The current day has its own pillar, and it meets each chart differently. Lumia’s compatibility reading ends with today between you: a day that favours one of you more than the other, a day to decide something together, a day to give each other room. Your compatibility doesn’t move with the day. The day is weather.

Where Western astrology comes in

Lumia’s compatibility reading is BaZi: the two charts’ elements and day pillars, and what today does to the pair. Western synastry (Venus, the Moon, the seventh house, the aspects between two charts) is a separate method, and each person’s own birth chart still shows how they love. Compatibility readings covers the whole picture. Back to BaZi.

Frequently asked questions

How does BaZi compatibility work?

It reads two charts for how their elements meet. First: what each day master is and what it needs. Second: whether the other chart supplies it. A chart rich in the element that feeds your day master is natural support; one rich in the element that controls it is friction you have to manage.

Is BaZi compatibility only for romance?

No. The same reading works for a business partner, a parent, a friend or a colleague. What changes is which parts of the two charts you weigh: the day branch for a partner, the month pillar for family, the hour pillar for children.

Do I need the other person's birth time?

Their date gives three of the four pillars, which is enough for a reading. The hour pillar sharpens it. You can add a person in Lumia with whatever you know.
