Yang, Fang (12. september 2011). «Mid-Autumn Festival and its traditions». Xinhua News Agency. Besøkt 12. september 2011. «The festival, celebrated on the 15th day of the eighth month in the Chinese calendar, has no fixed date on the Western calendar, but the day always coincides with a full moon. It is also known as the Moon Festival. Descriptions of "Mid-Autumn" first appeared in "Rites of the Zhou," a collection of ritual matters of the Western Zhou Dynasty 3,000 years ago. It described the eighth lunar month, the second month of autumn, as "mid autumn." The Chinese began celebrating the Mid-Autumn Festival in the early Tang Dynasty (618-907), a period of material abundance and cultural blossoming.»
