In Chinese astrology, particularly within Bazi (八字) or Four Pillars of Destiny, threshold years (起运年 or 大运起始年) refer to the age at which a person begins their first 10-year luck cycle (大运 - Da Yun).
Key Points About Threshold Years: Definition:
It marks the transition from childhood luck to personal luck cycles in Bazi analysis.
The starting age is calculated based on gender, birth year’s heavenly stem, and solar terms.
How It’s Calculated:
Yang Year Males (阳年男) & Yin Year Females (阴年女) → Count forward from birth to next solar term.
Yin Year Males (阴年男) & Yang Year Females (阳年女) → Count backward from birth to previous solar term.
3 days ≈ 1 year (each day represents ~4 months in age).
Example:
If a Yang Male is born 5 days after the Winter Solstice (冬至), his threshold age is 5 ÷ 3 ≈ 1.67 years (starts luck cycle at ~1 year 8 months).
Significance:
Before the threshold year, a person’s fortune is influenced by parental or family luck.
After the threshold, personal Da Yun (大运) cycles begin, shaping career, health, and relationships.
