45．Every year，families throughout China gather together to enjoy some snacks and entertainment under the light of the full moon for the Mid-Autumn Festival，which is on the 15th day of the eighth month of the Chinese calendar.This year the holiday falls on September 13，less than two weeks away.While many families throughout the country and abroad celebrate the holiday in slightly different ways，one of most common and best-preserved tradition is devouring delicious moon-cakes containing all manner of fillings.People often give mooncakes to their family and friends as gifts，while many companies in China hand out the festive pastry to employees as well.
While the tradition of shangyue was practiced by many Chinese during the full moon of the eighth month - often considered to be the brightest and most beautiful full moon of the year - in ancient times，the tradition didn't become a fixed festival until the Tang Dynasty （618-907）.
