What is Bazi?八字
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 from calendrical and solar-term conventions. The result can be reproduced under the stated rules, but the interpretive tradition is not a scientific measurement or a guaranteed prediction. Learn more about what Bazi is →
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 combines the historical time-zone offset, longitude, and the Equation of Time before deriving the Hour Pillar. See the complete true solar time method →

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.
Wood (木 · Mu)
Wood (Mu) represents growth, initiative, and creative vision. People with strong Wood energy are pioneers — expansive thinkers who thrive on new beginnings and personal development.
Keywords: Growth · Vision · Initiative
Fire (火 · Huo)
Fire (Huo) is the energy of passion, charisma, and self-expression. Strong Fire brings warmth, leadership presence, and the courage to be seen — it is the element of visibility and enthusiasm.
Keywords: Passion · Charisma · Expression
Earth (土 · Tu)
Earth (Tu) embodies stability, nurturing, and reliability. Earth-dominant charts indicate a grounded, trustworthy nature — patient, supportive, and rooted in practical wisdom.
Keywords: Stability · Nurturing · Reliability
Water (水 · Shui)
Water (Shui) is the element of wisdom, adaptability, and depth. Water types are introspective and perceptive — fluid communicators who navigate change with quiet strength.
Keywords: Wisdom · Adaptability · Depth
The Generating Cycle (Shēng)
- Wood (木)→Fire (火)Wood feeds Fire — creativity fuels passion.
- Fire (火)→Earth (土)Fire creates Earth — passion hardens into stability.
- Earth (土)→Earth bears Metal — patience sharpens into precision.
- →Water (水)Metal collects Water — discipline deepens into wisdom.
- Water (水)→Wood (木)Water nourishes Wood — wisdom feeds new growth.
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.
JiǎWood · Yang
The great tree — sturdy, ambitious, leadership timber.
YǐWood · Yin
The climbing vine — flexible, adaptable, quietly persistent.
BǐngFire · Yang
The blazing sun — radiant, generous, hard to ignore.
DīngFire · Yin
The lantern flame — refined warmth, insight, and sensitivity.
WùEarth · Yang
The mountain — solid, protective, enduringly present.
JǐEarth · Yin
The fertile soil — nurturing, receptive, cultivates growth.
RénWater · Yang
the great ocean — vast, powerful, endlessly flowing.
GuǐWater · Yin
The morning dew — gentle, intuitive, penetrates softly.
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.
