Grand Fortune Starting Time Theory

Focus on precise calculation of Grand Fortune starting time in Bazi. Detailed explanation of gender differences, yin-yang year rules, solar term calculations, and the traditional 3-day=1-year conversion formula.

What is Starting Time?

In BaZi divination, there is a transition period from birth to entering the first Grand Fortune cycle, this point is called 'Starting Time'

Basic Concept

Starting time refers to the duration from birth to the beginning of the first Grand Fortune, usually expressed as 'X years X months'

Why It's Important

Starting time determines the starting points of various Grand Fortune stages in life, affecting the timing judgment of the entire BaZi pattern

How to Calculate

Based on birth time and the nearest solar term time difference, calculated through specific formulas to determine the accurate starting time

For example:If the calculated starting time is '3 years 6 months', it means:

  • For the first 3 years and 6 months after birth, fortune is mainly influenced by the original chart (birth BaZi)
  • After 3 years and 6 months, enter the first Grand Fortune (the first 10-year cycle)
  • After 13 years and 6 months, enter the second Grand Fortune, and so on

Calculation Principles of Starting Time

The calculation of starting time is based on the relationship between birth time and solar terms, requiring several steps

Detailed Steps:
Follow these steps to gradually calculate the starting time of fortune
1
Determine Year Stem Yin-Yang
Find the birth year's heavenly stem and determine if it's Yang or Yin stem
Yang Stems: Jia, Bing, Wu, Geng, Ren
Yin Stems: Yi, Ding, Ji, Xin, Gui
2
Determine Forward or Backward
Based on gender and year stem Yin-Yang, determine whether to go forward (find next term) or backward (find previous term)
Male Yang/Female Yin → Forward
Male Yin/Female Yang → Backward
3
Find Corresponding Solar Term
Forward finds the nearest solar term after birth, backward finds the nearest solar term before birth (only "Terms" not "Qi")
Why only "Terms"?
Because the 12 "Terms" are the standard for dividing months, each "Term" represents the beginning of a month, while "Qi" is the midpoint of the month
12 Solar Terms:Beginning of Spring, Insects Awaken, Clear and Bright, Beginning of Summer, Grain in Ear, Slight Heat, Beginning of Autumn, White Dew, Cold Dew, Beginning of Winter, Heavy Snow, Slight Cold
4
Calculate Time Difference
Calculate the time difference from birth time to solar term time, accurate to days (can have decimals)
5
Apply Conversion Formula
Use traditional conversion formula to convert days into starting age
Conversion Formula
Step 1: Calculate Years (3 days = 1 year)
Years = Days ÷ 3 (round down)
Step 2: Calculate Months (1 day = 4 months)
Months = (Days % 3) × 4 (round down)
Ex
Actual Calculation: 8.75 days
Years = 8.75 ÷ 3 = 2.916... = 2 years
Months = (8.75 % 3) × 4 = 2.75 × 4 = 11 months
Final Result: 2 years 11 months

Practical Case Studies

Understand the complete calculation process of fortune starting time through specific examples

Case 1: Male Born in Ji Year
Born January 1, 1990 00:00
Year Stem:Ji (Yin)
Gender:Male
Rule:Male Yin Reverse
Find Solar Term:Previous solar term (Major Snow)
Time Difference:24.53 days
Calculation: 24.53 ÷ 3 = 8.18 years = 8 years 2 months
Fortune Starting: 8 years 2 months
Case 2: Female Born in Ji Year
Born January 1, 1990 00:00
Year Stem:Ji (Yin)
Gender:Female
Rule:Female Yin Forward
Find Solar Term:Next solar term (Minor Cold)
Time Difference:4.94 days
Calculation: 4.94 ÷ 3 = 1.65 years = 1 year 7 months
Fortune Starting: 1 year 7 months

Ancient Fortune Wisdom

Though wealth and nobility are determined by the original pattern, poverty and prosperity depend entirely on fortune periods.

—— Di Tian Sui (《滴天髓》)

This quote from the classic text 'Di Tian Sui' explains that while one's potential for wealth and status is born in the original BaZi pattern, the actual realization of poverty or prosperity depends completely on Grand Fortune and annual fortune periods. It emphasizes the crucial role of starting time in BaZi analysis.
