Seasonal context
A local account should identify the community, event year and calendar used. A lunar festival near Shuangjiang must not automatically be assigned to the astronomical term’s Gregorian date.
The seasonal word “autumn” here follows the traditional Northern Hemisphere calendar. The Hong Kong Observatory relates many term names to ancient central Chinese weather and agriculture. Local weather and plant development may differ; Southern Hemisphere seasonal timing is reversed.
Regional example and limits
Local customs vary between communities and are distinct from the astronomical definition. The calendar definition alone cannot establish a persimmon custom, a ritual date or the practices of every Zhuang community.
