The Four Pillars

Your birth moment, read through the solar calendar and its 24 seasonal nodes, resolves into four paired columns — Year, Month, Day, and Hour — each carrying a Heavenly Stem above an Earthly Branch: eight characters in total, the 八字 (BaZi) itself. At the structural heart of any reading stands the Day Master (your Stem of birth-day) in dialogue with the Month pillar, the seasonal force that shapes everything around it.
