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.

Yang FireDay Master · 日主

Open this phase
  • Wood1 / 6

    generates the Day Master

  • Fire4 / 6

    same phase as the Day Master

  • Earth0 / 6

    Not present in the visible chart

  • Metal0 / 6

    Not present in the visible chart

  • Water1 / 6

    controls the Day Master

Earth and Metal do not appear in these 6 visible characters. Absence here is a chart fact, not an automatic good-or-bad verdict, though with no birth time this count runs over six characters instead of eight, so an absence here is a weaker observation than it would be with the hour pillar.
