About the BaZi Calculator
BaZi (八字), also known as the Four Pillars of Destiny, is a Chinese astrological system that has been practiced for over 1,000 years. It uses your birth year, month, day, and hour to create four "pillars" of Heavenly Stems and Earthly Branches.
The core of BaZi analysis is understanding your **Day Master**—the Heavenly Stem of your day pillar—and its relationship with the five elements (Wood, Fire, Earth, Metal, Water) present in your chart. A balanced chart generally indicates a smoother life, while imbalances point to areas that need attention.
BaZi also calculates your **10-Year Luck Pillars (Da Yun)**, showing the elemental influences that shape different decades of your life. This makes it particularly powerful for timing major life decisions.

Frequently Asked Questions
What is BaZi (Four Pillars of Destiny)?
BaZi, meaning 'eight characters' in Chinese, is a destiny analysis system using your birth year, month, day, and hour. Each of these four time units creates a 'pillar' with a Heavenly Stem and Earthly Branch, totaling eight characters that map your fate and personality.
What is a Day Master?
The Day Master (Ri Zhu) is the Heavenly Stem of your day pillar, representing your true self and core identity. It is one of ten stems: Jia/Yi (Wood), Bing/Ding (Fire), Wu/Ji (Earth), Geng/Xin (Metal), or Ren/Gui (Water). Yin stems are Yi, Ding, Ji, Xin, Gui; Yang are the others.
How do the five elements work in BaZi?
The five elements (Wood, Fire, Earth, Metal, Water) interact through cycles of production and control. Wood feeds Fire, Fire creates Earth (ash), Earth produces Metal, Metal collects Water, Water nourishes Wood. Control works in a different cycle. A balanced chart has harmonious element interactions.
What are 10-Year Luck Pillars?
Da Yun (大运) are the major luck cycles that change every 10 years. They are calculated based on your birth month pillar and gender. Each luck pillar brings different elemental energies that interact with your chart, influencing career, relationships, and health during that decade.
