You need both birthdays. Birth times make it sharper.

Short answer

Yes, you can check compatibility with two birthdays; birth times make it sharper. BaZi compares two Chinese birth charts, starting with each person's core element (the Day Master). When one element feeds the other, the bond tends to feel supportive; when one tames the other, expect friction that can push you both to grow. Each chart's full element mix and the forces (Ten Gods) between the charts add the detail.

How BaZi compatibility works

Each person's chart has a core element. Every element feeds one other element and tames one other element. Those two pulls describe how two people meet.

Feeding pairs. Wood feeds Fire, like dry logs keeping a fire alive. Fire feeds Earth, as it burns down to ash, and ash becomes soil. Earth feeds Metal, like gold and iron growing deep in the ground. Metal feeds Water, like dew gathering on cool metal. Water feeds Wood, like rain waking up a garden. These pairs tend to feel easy and warm.

Taming pairs. Wood breaks up Earth. Earth gives Water banks. Water cools Fire. Fire softens Metal. Metal cuts back Wood. These pairs rub, and handled well, that friction helps both people grow. Each pair has its own guide in the compatibility guide.

What the reading shows

  • Your two core elements. Whether one of you feeds the other, tames the other, or mirrors the other.
  • Your shared mix. Whether the two charts together cover all five elements or pile up in a few.
  • Your two guardians. How your two guardian spirits, out of 80, complement or challenge each other.
  • Easy places and rough places. Where you support each other without trying, and where it takes effort.

FAQ

Questions people ask

How does BaZi compatibility work?
BaZi compatibility analyzes how the Five Elements in two birth charts interact. The core comparison looks at how your Day Masters relate, whether through the productive cycle (supporting) or controlling cycle (challenging). A full reading also considers the overall element balance in both charts and the Ten Gods dynamics between them.
Is the controlling cycle bad for relationships?
No. Controlling relationships are not inherently negative. In BaZi, the controlling cycle creates healthy tension that drives growth and transformation. A Fire-Metal pairing, for example, means Fire refines Metal; this can show up as one partner pushing the other to become stronger. Every relationship has both productive and controlling dynamics.
What do I need for a BaZi compatibility reading?
You need the birth date and birth time for both people. The birth time determines the Hour Pillar, which significantly affects the reading. If you do not know the exact birth time, a partial reading based on date alone is still possible but less precise.
Can BaZi predict whether a relationship will work?
BaZi reveals the elemental dynamics between two people: where you naturally support each other and where friction is likely. It does not predict outcomes. Two people with challenging charts can build a strong relationship through awareness; two people with harmonious charts can still struggle. BaZi is a tool for understanding, not a verdict.
