Celebrated under the glow of a full moon, the Vietnamese Moon Festival—locally known as Tet Trung Thu—is a cherished tradition deeply rooted in the culture of Vietnam. This celebration takes place annually on the 15th day of the 8th lunar month, typically falling in September or October. Drawing inspiration from ancient moon worship customs, the festival is also called the Middle Autumn Festival in Vietnam, symbolizing reunion, gratitude, and abundance.

Let’s dive into the origin, customs, and magical experiences that make Tet Trung Thu one of Vietnam’s most enchanting holidays.

When is the Vietnamese Moon Festival in 2025?

The middle autumn festival in Vietnam is set according to the lunar calendar and will fall on Monday, October 6, 2025. This date marks the brightest full moon of the year, which is believed to bring good fortune and happiness.

Travelers are encouraged to explore Vietnam one to two weeks before or after the official date. Streets are adorned with lanterns, stalls brim with traditional treats, and lively performances create an electric atmosphere. It’s a time when communities gather, and visitors can fully immerse themselves in the festive spirit.

Origins and Cultural Significance

Vietnam’s agrarian society has long been influenced by the moon’s cycles. For over 4,000 years, Vietnamese farmers have used the lunar calendar to guide their agricultural activities, including rice planting and harvesting.

The Vietnamese moon festival originated as a celebration of successful harvests and communal harmony. The full moon in mid-autumn was seen as the most beautiful and auspicious, symbolizing completeness and unity. This period became a perfect opportunity to pay homage to the moon and share joy with loved ones.

One famous legend often told during this time is the story of Cuội, a woodcutter who was lifted to the moon with a magical banyan tree. This tale adds a mystical dimension to the festival and is especially beloved by children.

A Festival Dedicated to Children

What makes the middle autumn festival in Vietnam unique compared to similar celebrations in other Asian countries is its strong focus on children. Often referred to as the “Children’s Festival,” Tet Trung Thu is a joyous occasion where kids receive gifts, wear new outfits, and take part in colorful lantern parades.

In the evening, children light up the streets with handmade lanterns shaped like stars, butterflies, and animals. The five-pointed red star lantern is especially iconic, believed to represent purity and innocence.

Another highlight is the lion dance, or múa lân, performed to the rhythm of beating drums. A dancer wearing the mask of Ông Địa—the jovial Earth God—entertains children by playfully interacting with the lion. These performances captivate both kids and adults, making it a memorable evening for all.

Moon Cakes: The Symbol of Tet Trung Thu

No Vietnamese moon festival is complete without Bánh Trung Thu, or moon cakes. These rich pastries are essential offerings during the holiday, often placed on ancestral altars alongside a tray of five fruits to honor family traditions.

There are two main types:

• Bánh dẻo: soft, white, and made from glutinous rice.

• Bánh nướng: golden-brown and aromatic.

Fillings vary widely. Sweet versions include mung bean or lotus seed paste, while savory ones feature complex combinations of salted eggs, sausages, nuts, and dried fruits. Moon cakes are traditionally sliced and shared, often enjoyed with hot green tea.

Besides family celebrations, these delicacies are also gifted to friends, business partners, and colleagues as a gesture of respect and goodwill.

These images, preserved at the Albert Kahn Museum in France, showcase early 20th-century Tet Trung Thu celebrations in Hanoi—children playing with handcrafted lanterns and toys on Hang Gai Street.

Busy’s work documents a vibrant cultural heritage, including other iconic Hanoi landmarks such as Long Bien Bridge and the Temple of Literature, offering us a visual bridge to the traditions of old Vietnam.
