Enter your birth date, time, and location to generate your Four Pillars chart, find your Day Master, and see your Five Elements balance.
This BaZi Calculator uses the traditional Chinese lunisolar calendar system — a sophisticated timekeeping method refined over two millennia. Unlike Western astrology based on the solar zodiac, the Four Pillars Calculator maps your birth moment to a precise combination of Heavenly Stems and Earthly Branches derived from the interplay of the solar and lunar cycles. Each of your four pillars (Year, Month, Day, Hour) encodes elemental energies — Wood, Fire, Earth, Metal, and Water — that together form your BaZi birth chart. Our calculator faithfully implements this traditional system with accurate calendar conversion.

Your Four Pillars chart reveals elemental patterns that influence every area of life. A strong Fire Day Master often thrives in leadership and public-facing careers but may need to watch for burnout. An Earth-dominant chart suggests stability in relationships but benefits from cultivating flexibility. The balance and clash between your elements point to health tendencies — Wood relates to the liver and tendons, Water to the kidneys and bones. For complementary spiritual guidance, discover your personal angel number or explore your tarot reading.

Birth time accuracy matters in Chinese astrology because the Hour Pillar changes every two hours. Our calculator goes beyond clock time — when you enter your birth location, it applies true solar time correction to determine the actual solar hour at your birthplace. A birth recorded at 1:00 PM clock time in western China may correspond to a different solar hour than the same clock time in eastern China. This correction ensures your Hour Pillar is accurate, which professional Chinese astrology practitioners consider essential for a reliable reading.
