Enter two birth dates to see how your charts interact. The calculator looks at three layers — Day Master, Five Elements, and Chinese Zodiac year — and returns a 0–100 score with three short reflections you can read together. The framing is deliberate: this is a starting point for an open conversation, not a verdict on the relationship.
The Day Master layer (40% of the score) compares the two day stems — their element and yin/yang polarity — and reads how they sit in the generation and control cycles. The Five Elements layer (30%) measures how well the two charts together cover Wood, Fire, Earth, Metal, and Water, with a small bonus when one chart fills what the other lacks. The Chinese Zodiac layer (30%) uses the year-branch relationships (six harmonies, triple harmony, clash, harm, break) as a third independent signal.
The reflections are written in probabilistic, conversational language. We deliberately avoid decisive language about the relationship — no “you should” framing — because a chart-based score should help you talk more clearly, not give you a verdict to act on.
