Five-element profile
The element weights compare the chart internally and are not evidence of personality or achievement.

Core analysis
This case generates a Four Pillars snapshot from source-graded birth data for Neil Armstrong. Its purpose is to show a reproducible study format that keeps source notes, calculation parameters, element results and a public timeline together. The Day Master, element weights and pillar relations belong to a traditional divination model. They may be compared as cultural texts, but they do not establish causation for personality, choices or historical events. Read the source grade, parameters and factual timeline first, and treat the interpretation only as a framework.
