Formula Used

Bazi = Heavenly Stems + Earthly Branches (Year, Month, Day, Hour)

Where:

  • Heavenly Stems = The 10 heavenly stems (Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui)
  • Earthly Branches = The 12 earthly branches (Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai)
  • Year Pillar = Determined by the Chinese year of birth
  • Month Pillar = Determined by the Chinese month and year
  • Day Pillar = Determined by the solar day
  • Hour Pillar = Determined by the time of day

Example Calculation

Real-World Scenario:

Let's calculate the Bazi for a male born on March 15, 1990, at 14:30 (2:30 PM) in UTC+8 time zone.

Given:

  • Birth Date = March 15, 1990
  • Birth Time = 14:30
  • Gender = Male
  • Time Zone = UTC+8
  • Calendar System = Solar Calendar

Calculation:

1. Convert to Chinese calendar: March 15, 1990 is the 19th day of the 2nd month in the year Geng Wu (Metal Horse).

2. Determine Year Pillar: 1990 is Geng Wu (Yang Metal Horse).

3. Determine Month Pillar: 2nd month of Geng Wu year is Yi Mao (Yin Wood Rabbit).

4. Determine Day Pillar: March 15, 1990 is Ren Chen (Yang Water Dragon).

5. Determine Hour Pillar: 14:30 is Wu Wu (Yang Earth Horse).

Result: The Bazi chart is Geng Wu (Year), Yi Mao (Month), Ren Chen (Day), Wu Wu (Hour).

Common Mistakes & Tips

Many people select their current time zone instead of their birth place's time zone. This can result in an incorrect hour pillar calculation. Always use the time zone of your birth place, not where you currently live. If you're unsure, look up the historical time zone for your birth location and date.

The Chinese New Year falls on a different date each year (between January 21 and February 20). If you were born in January or February, you might belong to the previous Chinese year. For example, someone born on January 25, 1995, is still in the year of the Dog (1994) rather than the Pig (1995), as the Chinese New Year in 1995 was on January 31.

Bazi is a complex system with multiple layers of interpretation. Avoid oversimplifying your chart or making deterministic predictions. Your Bazi reveals tendencies and potentials, not fixed destinies. Consider consulting with a professional Bazi practitioner for a comprehensive analysis that takes into account the interactions between all elements in your chart.

Frequently Asked Questions

Bazi, also known as the Four Pillars of Destiny, is a Chinese astrological system that uses your birth date and time to create a chart consisting of four pillars: Year, Month, Day, and Hour. Each pillar contains a Heavenly Stem and an Earthly Branch, which represent different elements and animals in Chinese cosmology. This chart is used to analyze personality traits, life cycles, relationships, career paths, and more.

The accuracy of Bazi analysis depends on several factors. First, the accuracy of the birth data is crucial - even small differences in time can change the Hour Pillar. Second, the skill and experience of the interpreter play a significant role. Bazi is a complex system with many variables and interactions, so a thorough analysis requires expertise. Finally, Bazi reveals tendencies and potentials rather than fixed destinies, so its "accuracy" is more about providing insights than making precise predictions.

Bazi is not a fortune-telling tool that predicts specific events. Instead, it reveals the cycles and patterns in your life, showing when certain energies are stronger or weaker. It can indicate favorable periods for career advancement, relationships, or financial decisions, as well as challenging times that require caution. However, Bazi doesn't determine your future - it provides a map of potentials that you can navigate through your choices and actions. Think of it as weather forecasting rather than destiny.

If you don't know your exact birth time, you can still calculate your Year, Month, and Day pillars, which provide significant insights. However, without the Hour Pillar, your chart will be incomplete. The Hour Pillar represents your career path, children, and later life in Bazi analysis. Some practitioners use rectification techniques to estimate the birth time based on major life events, but this requires consultation with an experienced Bazi expert.
