Traditional Tet is one of the most essential festivals of Vietnam. Traditional New Year's Day is called Lunar New Year or Lunar New Year, and is considered the most important moment of a year. The time starts on the 1st day of the 1st lunar month of the new year. The Lunar New Year usually falls between the end of January and the middle of February of a calendar year. Normally in Vietnam, every occasion to prepare for the Lunar New Year, everyone, whether working or going to school, has a holiday schedule. Normally, the time off is from one working week or more (for employees) and two to three days before December 30th. To prepare for the important Tet holiday of this year, every family often buys a lot of new things, cleans the house, prepares a tray of rice to worship ancestors. And yet, on the traditional New Year's Day, there is also a custom to visit the elderly, family members, friends and neighbors every time Tet comes. At that time, homeowners or adults will give lucky money to children and elders with wishes at the beginning of the new year of peace, prosperity, and everything as desired. This is not only a custom but also a cultural beauty of the Vietnamese people, to show concern and hope for a full and peaceful life for everyone.
