Start with your Day Master and chart relationships

Your shown Day Master is 壬 Ren, Yang Water. It is the day stem against which the chart names other stems. Without a birth time, a 23:00–23:59 birth may move the day pillar under this site's late-Rat convention.

Visible phase balance

What this chart is made of

Each pillar carries a phase in its stem and another in its branch. The 6 visible characters below are the first layer a reading compares with the Day Master.
