Which ethnic groups in Vietnam do not celebrate Lunar New Year?

TPO - Tet Nguyen Dan is considered the oldest and most important holiday for Vietnamese people. However, not all ethnic groups in our country celebrate the New Year on this occasion. Which ethnic groups are they?

The correct answer is B: The Cham people have two major holidays considered as Tet, which are Pang-Kate (July 1st of the Cham calendar, around September of the solar calendar) and Pang-Chabư (July 16th of the Cham calendar, around February-March of the solar calendar). According to the Cham people's concept, Pang-Kate is a day of worship for the ancient Cham kings who founded the country and guided the construction of farms. This Tet belongs to the father, symbolizes the positive energy and is celebrated in the early morning. Meanwhile, Pang-Chabư Tet is a worship for the Po Giang goddesses. They are the Cham queens and princesses, from the mother's family, symbolize the negative energy so it is celebrated in the evening.
