Why don't I get along with my brother or sister?

The chart often shows it: a clash between your month pillars (the siblings' palace), a Day Master check, or a 劫財 rivalry. It describes how you react to each other, and naming it is the first step to getting on better.

Does birth order matter in Bazi?

Not directly: Bazi reads each chart on its own. Birth order shows up through the year pillars, since siblings close in age have neighbouring year animals, which tend to combine or harm.

Yes, with both birth times. Twins often share three pillars, so the hour pillar makes the difference.

Which siblings get on best?

Same-element Day Masters (比和) and combining pairs score highest, especially with month pillars in harmony. Feeding pairs make a carer and a cared-for, which also works well.

Does it work for half-siblings or step-siblings?

Yes. The reading is based on your two charts, not on family ties. For a step-sibling you met as an adult, the friends page may describe you better.

Is there a full reading for siblings?

Yes. The AI reading writes five chapters about the two of you as siblings: your match, your roles, what you share, rivalry and timing. Chapter 1 is free with an account.

How Bazi reads siblings

Siblings share a home, parents and often a generation, so the siblings score looks at the pillars that describe them.

Siblings' palace (月柱): the month pillar is the traditional seat of brothers and sisters.
Friend star (比劫): siblings are the classic 比肩 and 劫財.
Year animals, 20%: the age gap and birth order count double.
Day Masters, 25%: same-element siblings score high.

The element exchange (25%) shows how much you can rely on each other once you have homes of your own.

Rivalry and support

A sibling who is your 比肩 is like you and understands you; one who is your 劫財 is like you and competes with you. Rivalry is strongest when you are close in age and your month pillars clash; it fades once each of you has your own field.

A sibling whose Day Master feeds yours (印星) often acts like a second parent; one you feed (食傷) is the one you look after. Those roles can last into adulthood, so it helps to notice them.

Twins and siblings born close together

Twins usually share the year, month and day pillars and differ only in the hour pillar, so their match depends on the birth times. Siblings born a year apart have neighbouring year animals, which often combine or harm each other.

For twins, enter both birth times as exactly as you can: a few minutes can change the hour pillar.

Getting on as adult siblings

The element exchange says the most about adult siblings: a high one means you recharge each other, so shared time is worth protecting; a low one means you are different types, so meet on neutral ground and let each other be.
