What is Bazi?
Bazi (八字), also known as the Four Pillars of Destiny, is a Chinese astrological system that maps your life path using the Heavenly Stems and Earthly Branches of your birth year, month, day, and hour. Each pillar reveals your elemental makeup, personality traits, and life rhythm. Originating over 1,000 years ago in the Tang Dynasty and refined in classical texts like "Yuan Hai Zi Ping" (渊海子平) and "Di Tian Sui" (滴天髓), Bazi remains one of the most accurate forms of Chinese destiny analysis.
"Bazi numerology probes the boundary between Heaven and Humanity, comprehending the transformations through all ages. Observe the Yin and Yang of the Four Pillars, examine the waxing and waning of the Five Elements; determine the purity or turbidity of the chart structure, and judge the gain or loss of the useful god." — Zi Ping Zhen Quan (Original Preface), by Chen Sufeng (Qing Dynasty)

Frequently Asked Questions
What is a Bazi calculator?▼
A Bazi (八字) calculator converts your birth date and time into a Four Pillars of Destiny chart — the foundation of Chinese astrology. According to "Yuan Hai Zi Ping" (渊海子平), one of the most authoritative Bazi texts, each "pillar" contains a Heavenly Stem and Earthly Branch, together revealing your elemental makeup, life path, and luck cycles.
Is this Bazi calculator really free?▼
Yes — completely free. Your chart, Ten Gods, Five Elements balance, luck cycles, and AI reading all appear instantly. No email, no credit card, no paywall.
How accurate is Bazi?▼
Bazi is a 1,000+ year-old metaphysical system documented in classical texts like "Di Tian Sui" (滴天髓) and "San Ming Tong Hui" (三命通会). Accuracy depends on correct birth time and skilled interpretation. Our AI is trained on these classical texts, but treat it as guidance — not destiny.
What do I need to calculate my chart?▼
Your birth date, birth time (as precisely as you know it), and birth location. If you don't know the exact time, you can still get a partial chart.
What is a Day Master?▼
Your Day Master (日主) is the Heavenly Stem of your Day Pillar. It represents you — your core personality, strengths, and weaknesses. It's the most important single element in your chart.
What are luck cycles (大运)?▼
Luck cycles are 10-year periods in your life, calculated from your birth chart. Each cycle is governed by a different element combination that either supports or challenges your Day Master — helping you time major life decisions.
Can Bazi predict my future?▼
Bazi doesn't predict specific events. It reveals the energetic patterns and timing of your life — helping you understand when to act and when to wait. Think of it as a weather forecast for your life, not a crystal ball.
How is this different from Western astrology?▼
Western astrology uses planetary positions at birth. Bazi uses the Chinese solar calendar with Five Elements (Wood, Fire, Earth, Metal, Water) and yin-yang theory. Both map your cosmic blueprint — they just use different coordinate systems.

References & Classical Sources
1. Yuan Hai Zi Ping (Source of Submerged Peace)— Traditionally attributed to Xu Ziping (c. 10th century, Song Dynasty). The foundational text of Bazi numerology. First systematically established the Four Pillars interpretive framework centered on the Day Master and structured around the monthly order. The source of all subsequent Zi Ping school teachings.
2. Di Tian Sui (Drops of Heaven's Water)— Old attribution to Jing Fang (Han Dynasty), but actually a distillation of orally transmitted verses by generations of numerologists. Expounds the deepest principles of Yin-Yang and Five Elements in poetic form. Revered as the "heavenly text of numerology" and essential reading for understanding the philosophical depths of Bazi.
3. San Ming Tong Hui (Comprehensive Collection of Three Fate Systems)— By Wan Minying (1603, Ming Dynasty). 12 volumes. The great compendium of pre-Ming numerology, covering everything from Five Elements interactions to Shen Sha and Na Yin, from Da Yun and Liu Nian to family structures. The only numerology text officially included in the Qing Dynasty imperial encyclopedia Siku Quanshu.
4. Qiong Tong Bao Jian (Precious Mirror for the Poor)— Compiled by Yu Chuntai (Ming Dynasty). Focused exclusively on the "Seasonal Adjustment God" (Tiao Hou) doctrine. Systematically discusses the preferences and taboos of each of the ten heavenly stems across the twelve seasonal environments. The core text of the Tiao Hou school, vastly enriching the nuance of Bazi interpretation.
5. Zi Ping Zhen Quan (True Interpretation of Zi Ping)— By Shen Xiaozhan (Qianlong era, Qing Dynasty), with additions by Zhang Zhongshan. Systematically organizes the three core methodologies: chart structure theory, useful god theory, and strength/weakness theory. Established the modern three-part Bazi analytical framework: Useful God → Chart Structure → Annual Cycles.
