Da Yun Starting Time: How to Calculate the First Cycle
What Starting Time Means
Anchoring the First Grand Fortune
The start time (Qi Yun) of Grand Fortune is determined by the time gap between birth and the nearest solar term. Direction uses the Yin-Yang of the birth year with gender, and the calculation uses solar terms (not qi). The traditional conversion is three days for one year, one day for four months, and one hour for ten days.
Why Start Time Changes Outcomes
Career & Wealth
A slightly different start age can shift which decade aligns with major career windows.
Love & Relationship
Relationship timing may appear earlier or later depending on start time accuracy.
Personality
The natal core does not change, but the age of expression can shift.
Use accurate starting time to plan high-effort phases and recovery cycles.

Consistency matters. If you adopt another lineage, keep it consistent across all readings.
Precision matters most near boundary hours or when the nearest solar term is close.
