Tet Nguyen Dan

Tết, also known as Tết Nguyên Đán, is the most important celebration in Vietnamese culture, marking the arrival of spring based on the Vietnamese calendar and typically occurring in January or February in the Gregorian calendar. The festival is based on a lunisolar calendar and is generally celebrated on the same day as Chinese New Year, with the Vietnamese people setting aside the troubles of the past year and hoping for a better and happier upcoming year. Tết has its origins in Chinese customs, but has evolved over time to reflect Vietnam's distinct culture and identity, with unique traditions such as the use of the lunar calendar, the giving of lucky money in red envelopes, and traditional Vietnamese dishes.learn more on wikipedia
