Sources and limits

Korean lunar conversion and solar-term-based sexagenary calculation are used. Results can differ for births recorded outside Korea or when the recorded time is uncertain. Interpretations are cultural references, not validated predictions.

Year and month use exact solar-term instants. Day uses the chosen rollover. Hour uses two-hour branches. Historical Korean daylight saving is considered.
