Reading the margin column. A term falling within minutes of civil midnight is a threshold case: implementations that differ by seconds can legitimately print a different date for it. Historical tables (pre-1929) also used Beijing Local Mean Time for the civil date — see the accuracy report §7 for the full attribution of every known divergence.

What 節 vs 氣 means for charts: month pillars flip at the 12 節 (節 jié), never at the 中氣 (中氣 zhōngqì). See lower/replacement trigram zones and the Lichun year-pillar rule.
