Labor Day in Vietnam is celebrated on May 1st each year unless the day falls on a weekend day then the holiday is observed on the following Monday. This day celebrates the workers movement as well as the changing season from Winter to Spring.
People will spend the day relaxing with family and friends. Some will attend a union or workers parade event to celebrate the advancement of workers rights.
Labor Day is a relatively new holiday because the workers movement did not get much attention until the late eighteenth and early nineteenth centuries when factory workers human rights were violated with extreme work conditions.
