BaZi Basics: The Four Pillars and Eight Characters
BaZi translates a birth timestamp into four columns of time—Year, Month, Day, and Hour—each written with one Heavenly Stem and one Earthly Branch.
Most people first meet the Chinese calendar through a single birth-year animal. This topic shows why that familiar zodiac sign is only one-eighth of a complete chart. Start with the three selected links below to see how the four columns are arranged, what the top and bottom rows represent, and why the Day Master in the day column serves as the chart's primary reference point.
Once you can read the two-by-four grid without getting lost, move through the full article list below to build a working vocabulary. You will learn how to treat the eight characters as a structured language for reflection and conversation rather than a fixed script about your fate, and understand what changes when your exact birth hour is uncertain.
