Start with the familiar Horse year, then read inward through month, day and hour. Every coordinate below opens into the guide that explains it.

Four nested zodiac rings illustrating year, month, day and hour layers
年 · 月 · 日 · 時Year, month, day and hour nested in one moment
Start with your Day Master and chart relationships

Your shown Day Master is 辛 Xin, Yin Metal. It is the day stem against which the chart names other stems.

  • Year stem 庚 Geng: Rob Wealth because Metal matches the Day Master's Metal, with different polarity.
  • Month stem 壬 Ren: Hurting Officer because Water is generated by the Day Master's Metal, with different polarity.

Visible phase balance

What this chart is made of

Each pillar carries a phase in its stem and another in its branch. The 8 visible characters below are the first layer a reading compares with the Day Master.

Hidden stems inside your chart

Your 4 calculated branches contain 8 hidden-stem occurrences. Primary, middle and residual name each stem’s place inside its branch.

Wood 1 · Fire 3 · Earth 3 · Metal 0 · Water 1. These are occurrences inside branches, counted separately from the visible characters; primary, middle and residual are not equal-strength weights.

Earth appears inside the branches even though absent from the visible-character count.
