Begin with the Four Pillars.
Understand what the Year, Month, Day, and Hour Pillars contribute before moving into interpretation.
Year Pillar
The Year Pillar (年柱, Niánzhù) is the first of the Four Pillars. It records the Heavenly Stem and Earthly Branch associated with the year boundary used by the calculation method.

The Month Pillar (月柱, Yuèzhù) places the chart within a solar-term month and seasonal environment. It is central to understanding context because the same sign behaves differently in different seasons.
Read guide →日Day Pillar
The Day Pillar (日柱, Rìzhù) contains the Day Stem—called the Day Master—and the Day Branch. The Day Master is the reference point used to name many relationships in a Bazi chart.
Read guide →时Hour Pillar
The Hour Pillar (时柱, Shízhù) records the two-hour Earthly Branch period of birth and its corresponding Heavenly Stem. It adds time-specific detail that cannot be reconstructed reliably from the date alone.
