Vietnam's New Year is celebrated according to the lunar calendar. It is officially known as Tet Nguyen Dan, or Tet. The Lunar New Year begins between January the twenty-first and February the nineteen. The exact date changes from year to year. Vietnamese people usually make preparations for the holiday several weeks beforehand. They tidy their houses, cook special food, clean and make offerings on the family altars. On the New Year's Eve, people sit up to midnight as they want to see New Year in. Then, they put on new clothes and give one another the greetings of the season. Tet lasts for ten days. The first three days are the most important. Vietnamese people believe that how people act during those days will influence the whole year. They make every effort to avoid arguments and smile as much as possible.
