Hanoi’s Spirit in the Run-Up to Vietnam’s National Day

Why does Hanoi turn red before September 2?

As National Day approaches, Hanoi begins to change. Red flags appear outside homes, on balconies and along streets across the city, while banners and decorations gradually fill public spaces.

For visitors, it is one of the clearest signs that September 2 is drawing near. The red flag with its yellow star is not only a national symbol, but also part of the atmosphere of Hanoi during this special time of year.

2025: A particularly memorable National Day

The atmosphere was especially remarkable in 2025, when Vietnam celebrated the 80th anniversary of National Day.

In the days leading up to September 2, Hanoi hosted large-scale military parade rehearsals. Soldiers, military vehicles and aircraft moved through the capital, turning familiar streets into the setting for one of the year's most anticipated events.

For many people, the rehearsals became an event in themselves. Families and groups of friends arrived hours in advance, lining the streets to watch the formations and military vehicles pass by.

For those who were in Hanoi at the time, the 80th anniversary offered a rare glimpse of the capital marking an important moment in Vietnam's modern history. The flags, crowds, soldiers and aircraft made 2025 an especially memorable National Day.

What is National Day usually like in Hanoi?

Not every year is celebrated on the same scale as 2025. But around September 2, Hanoi still takes on a distinctive atmosphere.

Flags appear throughout the city, central streets become livelier, and places connected to Vietnam's modern history, especially Ba Dinh Square, take on an added significance.

For travellers, it is a chance to see another side of Hanoi: one where everyday life, history and national celebration come together.
