Day Master Strength and Month Command in Bazi
Learn how the month command, roots, support, drain, control, and seasonal phases contribute to a Day Master strength judgment in Bazi.
Overview
Month command is the seasonal frame supplied by the month branch. It is primary evidence for qi availability, but strength still requires roots, visible support, drains, controls, combinations, and competing chart evidence.

What the Strength and Month Command catalog covers
This category separates month command, receiving or losing season, ground and momentum support, the five seasonal phases, strength bands, following structures, and extreme-strength treatment.
This hub organizes 52 indexed topics under one editorial model so definitions, derivations, interpretation order, and limits remain consistent across the catalog.
- Begin with the definition before using an interpretive keyword.
- Keep the named concept connected to stems, branches, season, placement, and the complete chart.
A disciplined reading sequence
Confirm the exact solar-term month and its branch, map seasonal relationships, then audit roots, generators, peers, drains, controls, transformations, and counterevidence before assigning a strength band.
Record the observed chart facts first, then state the rule being applied, and only afterward form a bounded interpretation. This separates calculation from judgment.
- Confirm the input, lookup anchor, and chart position before interpreting.
- Check whether season, strength, combinations, and timing support or weaken the proposed reading.
Evidence, school differences, and limits
A defensible conclusion records the month branch, seasonal phase, root map, visible and hidden support, opposing forces, relevant interactions, and the convention used for disputed following structures.
Strong and weak describe a technical balance of chart evidence. They do not measure character, health, physical power, social value, or whether a life will be good or bad.
- Treat named rules as evidence with a stated scope, not as automatic life-event predictions.
- When traditions differ, identify the convention instead of blending incompatible thresholds.
