Reference excerpt

The Mid-Autumn Festival, also known as the Moon Festival or Mooncake Festival, is a harvest festival celebrated in Chinese culture. It occurs on the 15th day of the 8th month of the Chinese lunisolar calendar and can fall between 7 September and 8 October (inclusive) of the Gregorian calendar. On this day, the Chinese believe that the moon is at its fullest and brightest, coinciding with the time of harvest in the middle of autumn. The Mid-Autumn Festival is one of the most important holidays and celebrations in Chinese culture. The history of the festival dates back now over 3,000 years. Similar festivals are celebrated by other cultures in East and Southeast Asia. During the festival, lanterns of all sizes and shapes – symbolizing beacons that light the path toward prosperity and good fortune for the people – are carried and displayed. Mooncakes, a rich pastry typically filled with sweet-bean or lotus-seed paste, are eaten during this festival. The Mid-Autumn Festival is based on the legend of Chang'e, the Moon goddess in Chinese mythology. It is an official holiday in both China and Taiwan and the day after the Mid-Autumn Festival is an official holiday in both Hong Kong and Macau.

Etymology The festival is so-named as it is held around the autumn equinox on the 15th of the 8th lunisolar month in the Chinese calendar. Its name varies among Sinitic languages, with the most common one being Mid-Autumn Festival or simply Mid-Autumn (中秋), as well as its traditional calendar date, either Fifteenth of the Eighth Month or Half of the Eighth Month, which is more regional. Other regional names include Eighth Month Festival, used in places such as Northeast China, Southern Fujian, and Jianghuai; Festival of Unity (simplified Chinese: 团圆节; traditional Chinese: 團圓節; Wugniu: doe2-yoe2-ciq7; Nanjingese: tuang2 üän2 zie5), used in Shanghai and Nanjing; and Mooncake Festival (simplified Chinese: 月饼节; traditional Chinese: 月餅節; Jyutping: jyut6 beng2 zit3), used in Guangdong and Hong Kong. Outside China, there are several other names for the festival:

Chuseok (추석; 秋夕; lit. ''autumn eve''), Korean festival celebrated on the same day in the Chinese and other East Asian lunisolar calendars. Tsukimi (月見; lit. 'moon viewing'), Japanese variant of the Mid-Autumn Festival celebrated on the same day in the Chinese lunisolar calendar. Moon Festival or Harvest Moon Festival, because of the celebration's association with the full moon on this night, as well as the traditions of Moon worship and Moon viewing. Tết Trung Thu (節中秋 in Chữ Nôm), in Vietnam. Also known as The Children's Festival in Vietnam. Most festival songs are sung by the children. Lantern Festival, a term sometimes used in Singapore, Malaysia and Indonesia, which is not to be confused with the Lantern Festival in China that occurs on the 15th day of the first month of the Chinese calendar. However, 'Mid-Autumn Festival' is more widely used by locals when referring to the festival in English and 'Zhōngqiū Jié' is used when referring to the festival in Chinese. Bon Om Touk, or The Water and Moon Festival in Cambodian. The festival is held each year in November for 3 days.

Meanings The festival celebrates three fundamental concepts that are closely connected:

Gathering: Such as family and friends coming together, or harvesting crops for the festival. It is said that the Moon is the brightest and roundest on this day which means family reunion. Consequently, this is the main reason why the festival is thought to be important. Giving thanks: To give thanks for the harvest, or for harmonious unions through activities like giving mooncakes to each other. Praying (asking for conceptual or material satisfaction): Praying for things such as babies, a spouse, beauty, longevity, or a good future Traditions and myths surrounding the festival are formed around these concepts, although traditions have changed over time due to changes in technology, science, economy, culture, and religion.

Origins and development The Chinese have celebrated the harvest during the autumn full moon since the Shang dynasty (c. 1600–1046 BCE). The term mid-autumn (中秋) first appeared in Rites of Zhou, a written collection of rituals of the Western Zhou dynasty (1046–771 BCE). As for the royal court, it was dedicated to the goddess Taiyinxingjun (太陰星君; Tàiyīn xīng jūn). This is still true for Taoism and Chinese folk religion. The celebration as a festival only started to gain popularity during the early Tang dynasty (618–907 CE). One legend explains that Emperor Xuanzong of Tang started to hold formal celebrations in his palace after having explored the Moon-Palace. By the Ming and Qing Dynasties, the Mid-Autumn Festival had become one of the main folk festivals in China. The Empress Dowager Cixi (late 19th century) enjoyed celebrating Mid-Autumn Festival so much that she would spend the period between the thirteenth and seventeenth day of the eighth month staging elaborate rituals.

Moon worship An important part of the festival celebration is Moon worship. The ancient Chinese believed in rejuvenation being associated with the Moon and water, and connected this concept to menstruation, calling it "monthly water". The Zhuang people, for example, have an ancient fable saying the Sun and Moon are a couple and the stars are their children, and when the Moon is pregnant, it becomes round, and then becomes crescent after giving birth to a child. These beliefs made it popular among women to worship and give offerings to the Moon on this evening. In some areas of China, there are still customs in which the "men do not worship the moon and the women do not offer sacrifices to the kitchen gods." In China, the Mid-Autumn Festival symbolizes the family reunion and on this day, all families will appreciate the Moon in the evening, because it is the 15th day of the eighth month of the Chinese lunisolar calendar, when the moon is at its fullest. Offerings are also made to a more well-known lunar deity, Chang'e, known as the Moon Goddess of Immortality. The myths associated with Chang'e explain the origin of Moon worship during this day. One version of the story is as follows, as described in Lihui Yang's Handbook of Chinese Mythology:

Worked examples

Example 1 — a first encounter with Mid-Autumn Festival

Start with the simplest possible case. Write down what Mid-Autumn Festival claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mid-Autumn Festival before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mid-Autumn Festival ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mid-Autumn Festival

In research: Mid-Autumn Festival appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mid-Autumn Festival in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mid-Autumn Festival is common in secondary-school and first-year university syllabi. It links to neighbouring topics Autumn equinox, Autumn in China, Buddhist festivals, so understanding it makes those chapters shorter.
In everyday life: Look for Mid-Autumn Festival outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
