How to read this sample
The Day Master is Geng Metal (yang metal), born in a Si month (early summer, when Fire is in season). Across the pillars, Metal appears 4 times and Fire 3 times — Metal is strong, and Fire tempers it; a single Earth feeds Metal, while Wood (wealth) and Water (output) are missing — suggesting talent expression and wealth channels need deliberate cultivation. The Year stem shows a Friend (peer) star and both the Month and Hour stems show Rival stars: strong peers with weak wealth stars favor building skills early rather than chasing money. Luck cycles run Ren-Wu, Gui-Wei, Jia-Shen from 1997, gradually strengthening Water and Wood — career expression and wealth channels open up from mid-life.

Worked Example: How FunTestHub Calculates the Year & Month Pillars
Unlike casual tools that mistakenly switch the zodiac year on January 1st or the Lunar New Year, authentic Four Pillars astrology strictly aligns the year transition with Li Chun (立春, Start of Spring) — the exact astronomical instant the Sun reaches ecliptic longitude 315°.
Month Pillars are derived identically using the astronomical moments of the 12 Jie Qi solar terms. Our calendar calculations are cross-validated against Purple Mountain Observatory ephemeris data.

Charts are calculated with lunar-javascript 1.7.7, using solar-term (Jie Qi) month boundaries. Interpretations follow the classical texts Yuan Hai Zi Ping and San Ming Tong Hui. For cultural and entertainment use.
Your birth time falls between 23:00 and 24:00 (late rat hour). BaZi traditions divide on whether the day rolls at midnight (00:00) or at 23:00. Our calculator follows the mainstream midnight rollover by default (current Day Pillar: ). Under the 23:00 rollover convention, your Day Pillar advances to tomorrow (). See our Methodology & Conventions for technical details.

What is Bazi (Four Pillars of Destiny)?
How to Read Your Bazi Chart?
Interpreting a Bazi chart focuses on several key dimensions:
- Day Master (Day Stem): Represents you, your core personality, and essential characteristics.
- Five Elements Balance: Measures the counts and strengths of Gold (Metal), Wood, Water, Fire, and Earth to see your energy balance.
- The 10 Gods (Shi Shen): Represents different facets of your life, career, wealth, and family relationships based on how other elements interact with your Day Master.
- 10-Year Major Luck Cycles (Da Yun): Indicates the energetic theme of each decade of your life, working together with individual years to shape your path.

Frequently Asked Questions (FAQ)
Q: What do the "Four Pillars" refer to?
A: The Four Pillars represent the Year, Month, Day, and Hour of your birth. Each pillar is composed of a Heavenly Stem and an Earthly Branch, totaling eight characters (Bazi).
Q: Does missing a certain element in my chart mean bad luck?
A: Not necessarily. Chinese astrology values the harmony and flow of energies rather than having everything equally. Missing elements can often be balanced or compensated through your name, career choices, colors, or geographical orientation.
Q: How do I use this online Bazi chart generator?
A: Simply select your solar (Gregorian) birth date and time, and our system will automatically look up the Chinese calendar, calculate the corresponding stems and branches, and generate a comprehensive destiny and element report.
Q: What calculation rules and calendar conventions are used?
A: Charts are calculated with the lunar-javascript 1.7.7 library. Year and month pillars are divided by exact solar-term (Jie Qi) boundaries, and day pillars follow the continuous sexagenary day cycle. Calculations use the local standard time you enter; no true-solar-time (longitude) correction is applied. For details, please see our About & Methodology page.
