Frequently Asked Questions
What is Bazi (八字) and how does it work?
Bazi, also known as the Four Pillars of Destiny (四柱命理), is an ancient Chinese astrological system dating back over 3,000 years. It calculates four "pillars" — Year, Month, Day, and Hour — from your exact birth date and time. Each pillar consists of a Heavenly Stem and an Earthly Branch, forming eight characters (八字 literally means "eight characters"). These eight characters encode your elemental composition, personality archetype, career tendencies, relationship dynamics, and life phases. Unlike Western horoscopes which use 12 zodiac signs, Bazi uses a matrix of 10 Heavenly Stems × 12 Earthly Branches, producing 518,400 unique destiny permutations.
Is the Bazi calculator on CosmicTao free?
Yes, our Bazi birth chart calculator is completely free to use. You can generate your full Four Pillars chart, see your Day Master element, Ten Gods relationships, hidden stems, and Five Elements balance — all at no cost. Advanced AI-powered interpretations and detailed life-phase analysis are available as premium features for registered users.
How does the True Solar Time correction work?
CosmicTao uses astronomical formulas to calculate True Solar Time (真太阳时) from your birth longitude. Standard timezone-based calculators can differ by dozens of minutes near boundary cases, which may shift the Hour Pillar. Our engine corrects for the Equation of Time and longitudinal offset so the chart uses a minute-level solar-time estimate before interpretation begins.
What is a Day Master (日主) and why does it matter?
The Day Master is the Heavenly Stem of your Day Pillar — it represents your core self, your fundamental character, and your psychological archetype. There are 10 possible Day Masters (甲乙丙丁戊己庚辛壬癸), each corresponding to a specific element and polarity (Yin/Yang). For example, a 甲 (Yang Wood) Day Master signifies leadership, ambition, and upward growth — like a towering tree. Understanding your Day Master is the single most important step in Bazi reading, as all other relationships (Ten Gods, favorable elements, life phases) are calculated relative to it.
What are the Ten Gods (十神) in Bazi?
The Ten Gods are ten relationship archetypes derived from the Five Elements cycle of generation (生) and control (克). They describe how each element in your chart interacts with your Day Master. For example: "Direct Wealth" (正财) represents stable income and a loyal spouse, while "Seven Killings" (七杀) represents fierce competition and authority under pressure. The Ten Gods system transforms abstract elemental theory into a practical personality and destiny framework — it is the psychological engine of Bazi.
How is Bazi different from Western astrology?
While Western astrology maps celestial positions (planets, houses, aspects) at birth, Bazi maps the temporal energy pattern using the Chinese lunisolar calendar. Key differences: (1) Bazi uses the Five Elements (Wood, Fire, Earth, Metal, Water) instead of planetary archetypes. (2) Bazi divides time into four pillars, not twelve houses. (3) Bazi calculations are deterministic and reproducible — the same birth data produces the same chart structure before interpretation. (4) Bazi includes "Luck Pillars" (大运), decade-long symbolic timing cycles used to discuss changing life themes.
What is the Five Elements balance and why is it important?
Every Bazi chart contains a specific distribution of the Five Elements: Wood (木), Fire (火), Earth (土), Metal (金), and Water (水). A balanced chart generally indicates a smoother life path, while extreme imbalances point to both challenges and exceptional talents. The concept of "Yong Shen" (用神, Useful God) identifies which element your chart most needs to achieve balance. This guides practical decisions — from career direction (Water-dominant people thrive in logistics, finance) to favorable colors, directions, and even dietary choices.
Can I use Bazi for relationship compatibility?
Yes. Traditional Chinese matchmaking (合婚) uses Bazi extensively. Our platform offers a dedicated Zodiac Compatibility engine that analyzes the Six Harmonies (六合), Three Harmonies (三合), Six Clashes (六冲), and Three Penalties (三刑) between two charts. Beyond the zodiac animal level, advanced Bazi compatibility examines whether two Day Masters have complementary elemental needs — a partnership where each person supplies what the other lacks is considered ideal.
Does CosmicTao provide a Bazi score or rating?
Yes, CosmicTao features a proprietary 100-point Bazi Scoring System. By combining traditional astrological algorithms with advanced AI, we quantify complex elemental interactions into intuitive scores for Wealth, Career, and Relationship potential. This quantitative approach allows you to instantly gauge the fundamental strengths and challenges within your Four Pillars destiny matrix without needing to decipher archaic texts.
