Four Pillars calculation record

Enter a Gregorian birth date and local clock time to produce a reproducible record of the four pillars, hidden stems, Ten Gods, Na Yin, branch relations, and raw element counts. The page does not predict the future or infer personality, career, wealth, health, or relationship outcomes from a Day Master or element count.

This is a traditional calendar-structure record, not a scientifically validated personality measure or prediction model. Identical input and version produce the same chart, but reproducibility does not validate an interpretation against real outcomes.

This tool does not collect birthplace or time zone, so it cannot correct daylight saving, longitude, or true solar time. Treat a time near 23:00, an hour boundary, or a solar-term boundary as an unresolved record that needs comparison.
