Metal and Metal Day Master Compatibility

Between a Metal Day Master and a Metal Day Master the basic relation is: the same element. Two people of the same element see each other as companions (比劫): easy recognition, but also competition for the same resources.

Each element has a yang and a yin Day Master, so this pairing covers 4 stem combinations. The Ten God each person represents for the other:

• 庚庚 Geng Yang Metal庚 Geng Yang Metal · Friend (比肩) · Friend (比肩)
• 庚庚 Geng Yang Metal辛 Xin Yin Metal · Rob Wealth (劫财) · Rob Wealth (劫财)
• 辛辛 Xin Yin Metal庚 Geng Yang Metal · Rob Wealth (劫财) · Rob Wealth (劫财)
• 辛辛 Xin Yin Metal辛 Xin Yin Metal · Friend (比肩) · Friend (比肩)

No stem combination occurs in this element pairing.

Day branches carry their own elements. Here are the relations between the main Metal branches and the main Metal branches — combinations bind, clashes and harms create friction.

• 申申 Shen申 Shen · punishment
• 申申 Shen酉 You · no fixed relation
• 酉酉 You申 Shen · no fixed relation
• 酉酉 You酉 You · punishment

Element qualities: Metal brings structure, cutting away, precision and principle; Metal brings structure, cutting away, precision and principle. In traditional imagery the pairing is read through how these qualities meet — reinforcing the same tendencies.

The fastest way to understand the Metal–Metal pairing is to look at real charts rather than memorise rules. Enter a birth date, time and city in the BaZi Calculator, then locate where the Metal–Metal pairing appears: in a visible stem, hidden inside a branch, in the current luck pillar or in this year's annual pillar. Note the position, because the year pillar is usually read as background and early life, the month pillar as environment and career setting, the day pillar as the self and close partner, and the hour pillar as later life and output.

• Compare two or three charts where the Metal–Metal pairing is prominent and two where it is absent; write down what differs in the overall balance.
• Check the month branch first: seasonal strength changes how much any factor matters.
• Use the hidden-stems and Ten Gods tables in the calculator output instead of guessing.
• Treat single factors as clues, never as verdicts; classical texts always weigh the whole chart.
• Enter both partners and compare Day Masters, day branches and the useful element of each chart.

Different schools describe the Metal–Metal pairing with slightly different emphasis. This site follows widely used conventions (solar-term months, true solar time optional, Zi hour setting configurable) and states them openly so you can compare results with a book or another calculator.

Element pairing is only the first layer. A fuller comparison looks at whether each chart supplies what the other lacks, at branch relations between the two day branches (combination, clash, harm), and at which luck pillars both people are in. Two charts of the "same" element pair can therefore read very differently.

• If one chart is short of Metal, a Metal partner literally brings that element.
• If one chart is already heavy in Metal, another Metal Day Master adds weight to the same side.
• Day-branch clashes and combinations matter as much as stems in traditional compatibility reading.

BaZi is a traditional cultural system. This page explains how the symbols are defined and read; it does not make scientific claims or predictions about your health, money or relationships.

1. Calculate the first chart in the BaZi calculator.
2. Open Compare with Another Person below the result and enter the second birth data.
3. Each chart is computed independently with the same rules; the comparison lists stem and branch relations between them and the Day Master relation in both directions.
4. Nothing about the second person is saved or shared unless you choose to.

Charts on this site use the published rule set: true solar time by default, the year changes at 立春 (Start of Spring), months change at the 12 节 solar terms and the day changes at 23:00. Example charts below are computed live by the same engine.

• "Compatible" is not a verdict. Classical texts describe dynamics, not pass/fail scores.
• Look at both directions: what A is for B can differ from what B is for A.
• Use luck pillars for timing questions rather than the natal pair alone.
• Study the individual guides for Metal and Metal first: Metal, Metal.
