The Eight Characters (BaZi) consists of four pillars—Year, Month, Day, and Hour—totaling eight characters. The Year Pillar boundary is based on Lichun (Start of Spring), and the Month Pillar is based on the 12 'Jie' (Major Solar Terms), not the first day of the lunar month.
Laying out the calculation process: where each pillar comes from, which solar term moment it's based on, and which rule is applied. Providing the basis, not giving judgments.
Many people believe that leap months alter the month pillar in BaZi, but the month pillar is determined by solar terms (節氣), not by lunar months. A leap month is merely a calendar adjustment in the lunar system and has nothing to do with the month pillar. This article explains the relationship between solar terms and the month pillar, and why leap months do not affect chart calculation.
