Bazi Master: Full-Chain Destiny Analysis

Automating Traditional Destiny Chart Construction

Manual Bazi (Eight Characters) charting involves tedious and error-prone steps such as checking almanacs, applying true solar time corrections, and dividing the year and month pillars based on solar terms. This skill encapsulates classical theories like the Zi Ping Zhen Quan into an executable analysis pipeline. Its core purpose is to solve the precise transformation problem from birth time data to a complete destiny chart structure. It is not merely a lookup tool but a computational system capable of handling complex cases like lunar-solar conversion, geographic time differences, and solar term boundaries.

From Four Pillars to Major Luck: The Core Computation Pipeline

The skill begins by processing the input birthday. Key steps include:

1. True Solar Time Correction: It uses the Baidu Geocoding API to obtain the birthplace's longitude and calculates the offset from Beijing Time (120°E). The birth time is automatically adjusted, which is fundamental for accurately determining the Day Pillar and Hour Pillar.
2. Solar Term-Boundary Pillar Calculation: The Year Pillar and Month Pillar are strictly divided by Lichun (Start of Spring) and the monthly Jie (solar term), respectively, not by the Gregorian calendar dates. The skill relies on an almanac API to fetch precise solar term times as the calculation basis.
3. Full-Chain Gan-Zhi Computation: Based on the corrected time, it automatically calculates the four pillars (GanZhiYear, GanZhiMonth, GanZhiDay, GanZhiHour) and their Nayin, and further computes the complete sequences of Da Yun (Major Luck), Liu Nian (Annual Luck), and Liu Yue (Monthly Luck).
4. Pattern and Useful God Analysis: After constructing the chart, the skill follows the core principle of the Zi Ping Zhen Quan that "the Useful God is specialized to depend on the Month Command." It provides a multi-dimensional Useful God selection logic—from Month Command appears in the Heavenly Stems to Balance/Restraint and Seasonal Adjustment—and outputs a comprehensive judgment of the Day Master's strength (身强身弱).

Analytical Framework and Caveats

This skill offers traditional analytical modules ranging from Shen Sha (spiritual stars, e.g., Tianyi Nobleman, Yang Blade) to Six Relations and the Twelve Life Stages. It is crucial to understand that all outputs are inferences based on the classical theoretical framework. All analysis results are for reference only. Due to the inherent complexity of destiny studies, tools like Shen Sha are supplementary; specific judgments require flexible analysis integrated with the overall chart and should never be mechanically applied. The calculation scope is limited by the almanac API and solar term algorithms used (e.g., the lunardate library supports years 1900-2100).
