Zi Wei Dou Shu Algorithm & Python Library Guide: Chart Calculation, Open Source Tools & Implementation

Keywords: zi wei dou shu, ziwei

1. History and Applications of Zi Wei Dou Shu

Zi Wei Dou Shu is an important branch of Chinese traditional astrology, originating from the integration of ancient I Ching principles and astronomical observations. As a destiny interpretation system based on celestial bodies and stellar configurations, it has been widely inherited by imperial nobility and folk scholars throughout history.

Applications:

• Personal Destiny Analysis: Helps individuals understand their personality, potential, health, marriage, wealth, and other aspects of life.
• Career Planning and Decision Making: Provides guidance on career changes and timing choices for job seekers and entrepreneurs.
• Cultural and Psychological Adaptation: Under modern life pressures, offers a path for self-understanding and internal adjustment through traditional astrology.
• Technology and Tradition Integration: In recent years, with the development of Big Data and AI, more astrological tools use algorithms for automated chart report generation, improving analysis efficiency and result readability.

2. Differences from Four Pillars of Destiny

While both Zi Wei Dou Shu and Four Pillars of Destiny are important systems in Chinese astrology, they have significant differences in principles and methodology:

• Theoretical Foundation:
  • Zi Wei Dou Shu primarily relies on stellar configurations, palace analysis, and four transformations theory.
  • Four Pillars of Destiny is based on the relationships between Heavenly Stems, Earthly Branches, and Five Elements.
• Chart Creation Method:
  • Zi Wei Dou Shu requires determining the destiny palace and placing stars in their respective positions.
  • Four Pillars focuses on calculating the eight characters based on birth date and time.
• Interpretation Perspective:
  • Zi Wei Dou Shu uses visual relationships between palaces and stars.
  • Four Pillars uses the balance of five elements and ten gods configuration.

3. Importance of Automation

With the rapid development of information technology, chart calculation automation has become crucial:

• Efficiency Improvement: Traditional manual calculation is time-consuming and error-prone.
• Standardization: Automated processes ensure consistency in calculations.
• Personalized Analysis: Software algorithms can quickly generate targeted reports.
• Data Collection: Automation facilitates data gathering for algorithm optimization.
• Multi-platform Access: Integration with various online tools and mobile applications.

1. Main Elements of the Chart

A complete Zi Wei Dou Shu chart consists of:

• Destiny Palace and 12 Palaces
• Major Stars and Minor Stars
• Four Transformation Stars
• Palace Stems and Body Palace
• Year, Month, and Day Cycles

2. Input Data Requirements

Required data for chart generation:

• Birth Date (Solar/Lunar Calendar)
• Birth Time (12-Hour System)
• Gender
• Optional: Birth Location

3. Core Calculation Steps

The calculation process includes:

• Calendar Conversion
• Destiny Palace Determination
• Star Placement
• Four Transformations Calculation
• Palace Relationships Analysis

1. Core Algorithm Challenges

While the Zi Wei Dou Shu chart generation process appears straightforward conceptually, several technical challenges need to be addressed:

a. Solar-Lunar Calendar Conversion

• Complex lunar calendar logic:
  • Leap month determination
  • Solar term divisions
  • Historical calendar rule coverage (from 1900 to present)

b. Solar Term Precision

• Star placement often depends on solar terms rather than fixed dates
• Requires precise calculation of 24 solar term transition times
• Needs high-precision astronomical calendar support

c. Star Placement Rule Variations

• Different schools (traditional vs. modern) have varying placement details
• Some support "full day chart" while others distinguish between "first/second half of night"
• Need configuration options or plugin mechanism for different algorithm branches

d. Body Palace and Lords Determination

• Multiple methods for body palace calculation across different schools
• Destiny and body lords selection involves year stem, birth hour, and gender
• Lack of standardized unified logic

2. Implementation Solutions

To address these challenges, consider the following solutions:

a. Calendar System

• Use established astronomical libraries
• Implement comprehensive validation
• Maintain detailed conversion tables

b. Calculation Precision

• Extensible Module Structure: Star calculations and chart logic can be implemented modularly for easy testing and optimization.
• Seamless API/Web Service Integration: Easy to return results in JSON format for frontend display or mobile app calls.

2. Module Structure Design

The Zi Wei Dou Shu calculation process can be divided into several functional modules:

Module Name	Function Description
lunar_converter.py	Solar ⇄ Lunar calendar conversion, solar term identification
time_utils.py	Timezone handling, true solar time correction
palace_locator.py	Determine destiny palace, body palace, palace sequence
star_allocator.py	Place major and minor stars according to rules
transformation_calc.py	Calculate four transformations based on year stem
chart_builder.py	Build final chart object (12 palaces, stars, transformations)

3. Example Implementation

Sample code for destiny palace location:

def locate_main_palace(year, month, day, hour, gender):
    """
    Locate destiny palace position (0-11, corresponding to twelve palaces)
    Parameters:
        year, month, day : birth date (solar)
        hour : birth hour (0-23)
        gender : "male" or "female"
    Returns:
        palace index
    """
    lunar_info = solar_to_lunar(year, month, day)
    lunar_month = lunar_info.month
    hour_index = get_hour_branch_index(hour)  # Zi = 0, Chou = 1 ...
    base_index = get_base_from_lunar_month(lunar_month)
    
    if gender == "male":
        palace_index = (base_index + hour_index) % 12
    else:
        palace_index = (base_index - hour_index + 12) % 12
    
    return palace_index

4. Technical Considerations
