It's known as Vietnamese Lunar New Year by foreigners. Tet takes place from the first day of the first month based on Vietnamese calendar (Âm Lịch) until the third day, but usually we celebrate Lunar New Year for a week more. Vietnamese people prepare for Tet by cleaning the house and cooking some special dishes like "Bánh Chưng", "Bánh Dày", "Bánh Tét", "Thịt kho Tàu", "Xôi", "Chè",... The preparation begins one week before the last night of the old year. I find that week tired but really fun and warm because everyone works hard to decorate the house beautifully to celebrate the arrival of spring. New Year means all the troubles of the past year gone and we hope for better upcoming year. That is why Tet is so meaningful and considered the national holiday in Viet Nam. Furthermore, Tet is the time for the whole family to gather and get to see each other. Sons and daughters who work far away from home will return to meet their parents and relatives. They will greet each other and wish them all the best in new year. Especially, people, usually young people will receive red envelop with money in it (lì xì), so I'm really excited when Tet occurs. During Tet holiday, it's Vietnamese traditional culture to worship at the family altar or visit the graves of their ancestors. The first day of Tet is reserved for family, i have a big family so we always have animated conversation when we gather. Those subsequent days are for relatives and friends, we have party all day long, sing and dance. Wonderful time!
