What the result means
Three astronomical-calendar layers.
Sexagenary day
The Heavenly Stem and Earthly Branch identify the day within the repeating 60-day cycle.
Month Establishment
The solar-term month branch establishes the reference point from which the Officer sequence is determined.
Operating quality
The resulting Officer describes the day’s broad mode of action and must still be matched to a specific objective.
Professional note: the displayed solar ecliptic longitude, λ⊙, supports auditing around solar-month boundaries. Consecutive Officers can legitimately occur during a month rollover.

Use the result well
Match the Officer to the exact action.
“Start,” “sign,” “launch,” “collect,” and “close” are different actions. Use the detailed Officer guidance to distinguish them before making a timing decision.
