What is Bazi?

Bazi (八字), also known as the Four Pillars of Destiny, is a form of Chinese astrology that maps your birth date and time into four pillars of Heavenly Stems and Earthly Branches. Each pillar reveals patterns about your personality, career, relationships, and life path. Unlike Western zodiac signs, Bazi is built on astronomical calendar data, making it remarkably precise.

How to Read Your Bazi Chart

Your chart has four pillars — Year, Month, Day, and Hour — each with a Heavenly Stem (天干) and an Earthly Branch (地支). The Day Stem is your Day Master (日主), representing your core self. Around it, the Five Elements (五行) — Wood, Fire, Earth, Metal, and Water — interact through generating and controlling cycles, shaping your strengths and challenges.

Why Your Birth Time Matters

Bazi uses true solar time, not clock time. Your exact birth location matters because longitude shifts the sun's position by minutes. Our calculator applies true solar time correction so your Hour Pillar is always accurate.

The Five Elements (Wu Xing)

In Bazi, the Five Elements — Wood, Fire, Earth, Metal, and Water — are not substances but energy types. Each charts a distinct temperament and set of strengths. Their generating and controlling cycles explain how the parts of your personality support or temper one another.

The Generating Cycle (Shēng)

The Ten Heavenly Stems (Tiangan)

The Heavenly Stems (天干) are the five elements split into Yang (active) and Yin (receptive) polarities, giving ten archetypes. The top character of each pillar in your chart is a Heavenly Stem — your Day Stem is the single most important character, representing your core self.

The Twelve Earthly Branches (Dizhi)

The Earthly Branches (地支) are the twelve two-hour windows of the ancient Chinese day, each paired with a zodiac animal and an element. The bottom character of each pillar is an Earthly Branch — your Year Branch is the familiar Chinese zodiac sign, while your Day Branch governs intimacy and relationships.
