- What is BaZi?
- BaZi (八字), or the Four Pillars of Destiny, is a Chinese astrology system that maps your birth year, month, day, and hour into eight characters — four Heavenly Stems and four Earthly Branches — revealing your day master and five-element balance.
- BaZi vs Zi Wei Dou Shu — what is the difference?
- BaZi focuses on the Five Elements and cyclical timing through the Four Pillars. Zi Wei Dou Shu maps fourteen major stars across twelve life palaces. Many practitioners use both: BaZi for elemental timing, Zi Wei for detailed life-domain readings.
- Is this BaZi calculator free?
- Yes. The Guanlan Energy BaZi calculator is free — enter your birth date and Chinese two-hour birth branch to view your Four Pillars chart and five-element profile in English with no payment required.
- Why does birth hour matter in BaZi?
- The hour pillar completes your Four Pillars chart. A different two-hour birth branch can change your hour stem and shift your elemental balance, so accurate birth time improves BaZi calculator results.
