Sexagenary cycle · position 17 of 60
庚辰
Yang Metal Dragon
This is one fixed meeting of a Heavenly Stem and an Earthly Branch. The stem supplies yang Metal; the branch supplies the Dragon and its twelve-position time coordinate.
Two coordinates, read together
What is fixed inside 庚辰
A pillar keeps the same stem and branch wherever it is used. What changes is its placement—as a year, month, day or hour—and the other pillars it is compared with.
A separate traditional association · 纳音
White-wax metal
Na Yin assigns one named image and phase to every pair of consecutive cycle pillars. It sits beside the visible stem and branch coordinates; it does not replace either one.

A coordinate, not a complete reading
What this pillar establishes
庚辰 fixes one stem–branch identity. A chart supplies the placement and comparisons that make that identity usable.
The pair fixes
- Yang Metal through 庚
- The Dragon branch and its time coordinates
- 白蜡金 White-wax metal as its Na Yin
- Position 17 in the repeating sequence
The chart still decides
Whether the pair is the year, month, day or hour pillar; which stem is the Day Master; and how the surrounding stems and branches relate to it. The pair alone does not rank a personality, promise an outcome or stand in for the other three pillars.
