Vietnam uses both the solar or Gregorian calendar (dương lịch) and lunisolar calendar (âm lịch) like most other Asian countries. However, most practical matters in daily life are based on and move in time with the solar calendar.

The lunisolar calendar is used to establish important seasonal holidays, important historic events, or to celebrate Vietnamese festivals and traditions. Some holidays vary from year to year because of the time difference between the lunisolar and solar calendars.

Tết Nguyên Đán or Tết (Vietnamese New Year) is the most important annual holiday and the only time of the year when people return to their ancestral hometown to celebrate the New Year with family and friends.

The window for Tet varies from year-to-year; from the last two days of the last lunisolar month, to the first three or four days of the new month (January or February depending on the year). Expect to find most businesses closed for a week from the beginning of this period. A lot of expats and foreigners also come from all over to see the activities that takes place during this season. You can find demonstration and rituals being done in temples and the street flooding with colorful traditional food and items for Tet.

Other than official public holidays, some foreign offices and embassies may observe extra bank holidays according to their countries of origin but if you’re looking for long weekends to schedule your vacations, you won’t find much of that here.
