About UseBazi
UseBazi is a free platform dedicated to bringing thousand-year-old Chinese metaphysics to the world. We believe that ancient wisdom should not be limited by language barriers or commercial interests — everyone deserves equal access to understanding their Bazi chart.
Our Mission
Our mission is to make the treasure of Chinese metaphysics — Bazi (Four Pillars of Destiny) — transcend cultural and linguistic boundaries, reaching every curious soul around the world who seeks self-discovery. Bazi is not merely an ancient astrological system; it is a sophisticated form of chronopsychology that analyzes the cosmic energy imprint of your birth moment to help you understand your innate talents, potential, and life rhythm.
That's why we provide completely free Bazi chart calculation and easy-to-understand interpretations. No paywalls, no commercial interests standing in the way of knowledge dissemination. Regardless of your country or language, you can access accurate chart results with ease.

Privacy First
All calculations happen in your browser. Your data never leaves your device.
How It Works
UseBazi's chart engine precisely calculates Heavenly Stems and Earthly Branches based on the Chinese solar calendar (Jieqi calendar). Solar terms are the core of the traditional Chinese calendar — each term marks the Sun's arrival at a specific ecliptic longitude. Our algorithm strictly follows the exact moment of solar term transitions to determine the boundaries of Year and Month Pillars, ensuring accuracy down to the two-hour time slot (Shichen).
Interpretation rules are drawn from classical Bazi texts, including "Yuan Hai Zi Ping" (渊海子平), "Di Tian Sui" (滴天髓), "San Ming Tong Hui" (三命通会), and "Zi Ping Zhen Quan" (子平真诠). These texts, refined over centuries, form the core theoretical framework of Bazi metaphysics. We have distilled their interpretation rules into structured data and combined them with AI assistance to generate easy-to-understand readings.
Most importantly, all calculations and data processing happen in your browser. Your birth information is never sent to any server, never stored, and never used for any other purpose. We believe that personal privacy and metaphysical exploration are equally important.
Our Values
Accuracy
Our engine uses traditional calendar algorithms with precise solar term calculations, accurate to the two-hour Shichen. We draw from authoritative classical texts and cross-reference multiple sources to ensure every pillar, stem, and branch is correct.
Accessibility
Free forever, no registration required, no email collection. We believe that self-knowledge tools should be available to everyone, not just those who can afford premium subscriptions.
Privacy
Your birth data is processed entirely in your browser. We do not store, transmit, or sell your personal information. There are no tracking scripts or analytics that could identify you.
Multilingual
By supporting English, Chinese, Japanese, and Korean, we enable people from different cultural backgrounds to benefit from this ancient wisdom. Knowledge should have no borders.
Disclaimer
Bazi is a precious traditional cultural heritage of China with over a thousand years of history. It provides a unique framework for self-reflection, helping people understand their personality traits, strengths, potential, and life rhythm from a different perspective.
However, Bazi should not be used as the sole basis for major life decisions (such as marriage, career, medical treatment, etc.). Every person's life is influenced by countless factors, including personal effort, environmental conditions, and social opportunities. We encourage users to approach Bazi results rationally — as reference and inspiration, not absolute guidance.
