Lunar New Year (also known as New Year[1], Tet Ta, Lunar New Year, Traditional New Year or simply Tet) is the first festival of the new year according to the lunar calendar of the ethnic groups of East Asia, including including China, Japan, Korea and Vietnam. According to historical fluctuations, the Japanese abandoned the Lunar New Year, while the Chinese, Koreans and Vietnamese still kept the tradition of celebrating this New Year even though they settled in other countries. In Vietnam before Tet, there are customs such as "offering the Tao Quan" (December 23 of the lunar calendar) and "offering the New Year" (December 29 or 30 of the lunar calendar). Because Tet is calculated according to the lunar calendar, Vietnam's Lunar New Year is later than the New Year (or Western New Year). Due to the rule of 3 leap years and a month of the lunar calendar, the first day of the Lunar New Year is never before January 21 and after February 19, but falls between these dates. The entire annual Lunar New Year holiday usually lasts about 7 to 8 days at the end of the old year and the first 7 days of the new year (December 23 to the end of January 7).[2
Every year, Tet is celebrated on the 1st day (or 1st day of January) of the lunar calendar throughout Vietnam and in a few other countries where the Vietnamese community lives. Buying peaches and kumquats in the North, Central or apricot in the South is considered an indispensable preparation in the days leading up to Tet. Then, during Tet, families gather together, visit relatives, give good wishes, celebrate age and worship ancestors.
