Brazil’s May 1 Labor Day is known as Dia do Trabalho.
The Portuguese name means “Workers’ Day” or “Labor Day.” May 1 is a national public holiday in Brazil and is associated with labor organizations, workers’ rights, and public gatherings.
Brazil’s observance belongs to the wider international tradition of celebrating workers on May 1. The date was adopted internationally after the Second International’s 1889 decision to support demonstrations connected with the eight-hour-day movement.
Brazil is sometimes confused with Portugal because both countries use Portuguese. Portugal also observes May 1, but the question’s country is Brazil, where the holiday is commonly called Dia do Trabalho. Brazil’s national day, Independence Day, is observed on September 7.
