What Is Day Virtue (日德) in BaZi?
Learn the five Day Virtue pillars, the different rules for a single or repeated match, the Kui Gang overlap and the limits of this classical pattern.
Overview
Day Virtue is the standard English name for 日德. The classical rule is limited to five complete day pillars: Jia-Yin, Bing-Chen, Wu-Chen, Geng-Chen and Ren-Xu. One match and repeated Day Virtue are not judged by the same shortcut: the source allows Wealth and Officer support for a single occurrence, but records different cautions when the pattern repeats. Clashes, punishments, harms, destruction, Void and a competing Kui Gang route can also change the reading. OpenFate calculates the day pillar and surrounding interactions but does not issue a Day Virtue pattern verdict.

Day Virtue starts with five exact day pillars
The source names Jia-Yin, Bing-Chen, Wu-Chen, Geng-Chen and Ren-Xu. Both the Day Stem and Day Branch must match; finding Yin, Chen, Xu or one of the five Yang stems elsewhere in the chart does not create this pattern.
The classical explanation assigns a different internal rationale to each pillar—such as Jia seated on Lu or other pillars holding Officer, Wealth and Resource relations. Those rationales are historical pattern language, not five interchangeable personality labels.
- Match the complete Day Pillar before discussing the name.
- Do not extend the allowlist by analogy.
Single, repeated and overlapping cases follow different routes
The text distinguishes one Day Virtue occurrence from a chart in which the listed pillars repeat. A single occurrence may be supported by genuine Wealth and Officer structure, while repeated cases carry separate cautions about Wealth, Officer and disruptive relations. The count and the actual Ten Gods therefore have to be shown rather than compressed into one score.
Geng-Chen is listed under both Day Virtue and Kui Gang. This is a source-defined overlap, not permission to merge the two rules. Month command, strength, ordinary pattern and the evidence for each route decide which description remains useful.
- Report the number and positions of exact matches.
- Keep Day Virtue and Kui Gang as separate hypotheses.
OpenFate verifies the components but does not certify the pattern
OpenFate can verify the complete day pillar, Wealth and Officer relations, strength context, Void, clashes, combinations, punishments, harms and the basic Kui Gang day marker. These are auditable chart facts.
There is no Day Virtue detector and no rule that arbitrates its single, repeated and Kui Gang-overlap branches. This page documents the historical test without changing existing reports, scores or the meaning of the basic Kui Gang output.
- Calculated facts and editorial pattern judgment remain separate.
- Fail closed when the full branch cannot be validated.
Day Virtue does not prove virtue, protection or life outcomes
Classical praise about kindness, rescue from danger, rank, prosperity and longevity is part of a premodern symbolic tradition. A favorable name cannot establish moral character or immunity from harm.
Do not use Day Virtue to assess trustworthiness, health, lifespan, legal risk, wealth or employment. Real decisions require present evidence and qualified professional advice.
- Do not convert the word “virtue” into a character rating.
- Exclude safety, status and longevity guarantees.
