About Vietnam holiday

By far the largest holiday of the year is Tết, celebration of the New Year (as marked by the lunar calendar), which takes place between late January and March on the Western calendar. In the period leading up to Tết, the country is abuzz with preparations. Guys on motorbikes rush around delivering potted tangerine trees and flowering bushes, the traditional household decorations. People get a little bit stressed out and the elbows get sharper, especially in big cities, where the usual hectic level of traffic becomes almost homicidal. Then a few days before Tết the pace begins to slow down, as thousands of city residents depart for their ancestral home towns in the provinces. Finally on the first day of the new year an abrupt transformation occurs: the streets become quiet, almost deserted. Nearly all shops and restaurants close for three days, (the exception being a few that cater especially to foreign visitors; and hotels operate as usual.)
In the major cities, streets are decorated with lights and public festivities are organized which attract many thousands of residents. But for Vietnamese, Tết is mostly a private, family celebration. On the eve of the new year, families gather together and exchange good wishes (from more junior to more senior) and gifts of “lucky money” (from more senior to more junior). In the first three days of the year, the daytime hours are devoted to visiting — houses of relatives on the first day, closest friends and important colleagues on the second day, and everyone else on the third day. Many people also visit pagodas. The evening hours are spent drinking and gambling (men) or chatting, playing, singing karaoke, and enjoying traditional snacks and candy (women and children.)
Visiting Vietnam during Tết has good points and bad points. On the minus side: modes of transport are jammed just before the holiday as many Vietnamese travel to their home towns; hotels fill up, especially in smaller towns; and your choice of shopping and dining is severely limited in the first days of the new year (with a few places closed up to two weeks). On the plus side, you can observe the preparations and enjoy the public festivities; pagodas are especially active; no admission is charged to those museums and historical sites that stay open; and the foreigner-oriented travel industry of backpacker buses and resort hotels chugs along as usual. Visitors also stand a chance of being invited to join the festivities, especially if you have some local connections or manage to make some Vietnamese friends during your stay. When visiting during Tết, it’s wise to get settled somewhere at least two days before the new year, and don’t try to move again until a couple of days after.
Lesser holidays include May 1, the traditional socialist labor day, September 2, Vietnam’s national day, King Hung celebration on April 12th, commemorating past kings, and Liberation Day on April 30th, marking the fall of Saigon in 1975. Around those times, trains and planes tend to be sold out, and accommodations at the beach or in Dalat are hard to find. Best to book far in advance.
