1. What is the Date of the Moon Festival in 2025?

The Mid-Autumn Festival, celebrated on the full moon day of the 15th day of the 8th lunar month, is a great festival in many Asian countries. In 2025, the Moon Festival will take place on Monday, October 6.

Plan your visit to the Mid-Autumn Festival in 2025 one to three weeks before or one to two weeks after it begins. During this season, streets and shops are adorned with bright red and yellow decorations, lanterns, and joyful markets. The atmosphere is exciting, with lion dances, cultural performances, and an abundance of mooncakes to savor.

2. The history of the moon festival in Vietnam

With a civilization largely based on rice farming for over 4,000 years, the Vietnamese hold various festivals following the lunar calendar to celebrate harvest prosperity.

The largest Vietnamese festival, Tet or the Lunar New Year, was once celebrated at the beginning of a new rice season. It was a time when farmers planted rice and plowed fields to ensure sufficient harvests for autumn.

A good harvest allowed farmers to avoid food shortages and have a stable financial situation. To celebrate rice and its nourishing and commercial virtues, the Vietnamese created the Harvest Festival - Tet Trung Thu.

You might wonder, what is the connection between the autumn full moon and rice harvests? Unlike the sun, the moon changes its face throughout the month and can even change shape from day to day. The deeply religious Vietnamese believe that the moon symbolizes the unity of the Vietnamese people, united and supportive.

The bright full moon in mid-autumn, the most beautiful night of the year, has even more significance as it represents the concept of completeness. Thus, the Mid-Autumn Festival is a perfect occasion to gather family members and celebrate a good agricultural harvest.

The Legend of Cuội 

Cuội, a woodcutter, discovered a magical tree that could bring the dead back to life. One day, he saw a mother tiger use its leaves to revive her cubs. Cuội took the tree home and saved many lives with its leaves.

Cuội’s fame grew, and he even revived a rich man’s daughter, marrying her. However, while Cuội was away, invaders killed his wife. His loyal dog offered its entrails to replace hers, and she lived, but became forgetful.

One evening, Cuội’s wife, not remembering his warning, used dirty water that had been used to wash feet to water the sacred tree. The ground shook, and the tree began to uproot. Cuội tried to save the tree, but it lifted him to the moon. Since then, Cuội has lived on the moon with his tree.

3. Tet Trung Thu, the Children’s Festival in Vietnam

Observing the Mid-Autumn Festival in other Asian countries, the traditions and rituals seem quite similar. However, notable differences exist in Vietnam as Tet Trung Thu is both a reunion event and a festival dedicated to children.

Indeed, this day can remind us of Children’s Day because kids receive lovely gifts or new clothes from their parents. In the evening, under a shining moon, children parade through the streets singing and carrying colorful lanterns of various sizes and shapes, such as star, butterfly, or fish-shaped lanterns. Some lanterns are red stars, the emblem of this festival, as the Vietnamese believe the star’s twinkling light symbolizes purity, like children’s innocence.

Good to know: September in Vietnam is Mid-Autumn season - one of the best times to visit and explore.
The traditional lion dance (múa lân) is a Mid-Autumn highlight. Acrobatic dancers bring the lion to life with drumbeats, its big head and bulging eyes looking both playful and a little scary under the full moon. In the parade, a masked dancer as Ông Địa (the Earth God) entertains the crowd, especially children.

Afterward, families share a festive banquet of fruits, sweets, and, of course, mooncakes: the stars of the Mid-Autumn Festival.

4. The Moon Cake Festival

Moon cakes, known as “Banh Trung Thu” in Vietnamese, are directly associated with the Mid-Autumn Festival in Vietnam. Across the country, families celebrate Tet Trung Thu by placing a tray of five fruits and several moon cakes on the ancestral altar to express their gratitude.

The two most popular moon cakes are Bánh Dẻo (soft, sticky cakes with a glutinous rice crust) and Bánh Nướng (baked cakes with a golden crust). Shaped into rounds or squares, they feature intricate designs like flowers, carp, or geometric patterns. The fillings of Bánh Trung Thu come in a variety of sweet and savory options.

The savory moon cake recipe is more complex than the sweet one, consisting of a dozen ingredients such as pork fat, sausages, jams, and various types of seeds and nuts. The sweet filling, on the other hand, is made from a single ingredient: mung bean paste or lotus seed paste. The moon cake is usually cut into small pieces and shared among family members. This sweet cake is traditionally accompanied by a hot cup of green tea.

During the Mid-Autumn Festival in Vietnam, moon cakes are generally given as gifts to family and friends. However, the Vietnamese also exchange moon cakes between clients and colleagues to demonstrate loyalty, sincerity, and commitment.

6. Mid-Autumn Festival in Vietnam 100 Years Ago

The color photographs of Mid-Autumn toys on Hang Gai Street, Hanoi in 1915, captured by photographer Léon Busy, open a gateway to the past. These are among the first color photos with high accuracy, showcasing skilled use of angles, character positioning, and lighting.

The Mid-Autumn toys, entirely handmade by Vietnamese ancestors, were intricate and aesthetically pleasing.
Besides the series on Mid-Autumn toys, Léon Busy also captured scenes of Hang Chen, Hang Thiec, Long Bien Bridge, Tran Vu Pagoda gate, the Temple of Literature, and Ngoc Son Temple in 1915. These are among the earliest color photos of Hanoi using autochrome technology. 

Today, 1,382 color photos of Vietnam and some early 20th-century film footage are preserved at the Albert Kahn Museum in France.
Albert Kahn, a French banker passionate about color photography for its vivid representation of life, funded equipment and hired photographers to capture color images from around the world. Léon Busy was sent by the Albert Kahn Museum to Vietnam to document daily life in Northern Vietnam from 1914 to 1917, giving us the chance to see ancient Vietnam.
