Labour Day, known locally as 'Darba Diena', is an official public holiday in Latvia. Celebrated on the 1st of May, it represents and commemorates the historical struggle and accomplishments of the working class. Having roots tracing back to the late 19th century, it plays a significant part in both the social and political spheres of the country, symbolizing the hard-fought rights of workers and the continuous aim of achieving better working conditions.

Historically, it was during the second International in 1889 when Labour Day was formally proclaimed to be a holiday recognising and honouring workers' rights worldwide. Like in many other countries, it was also adopted as a public holiday in Latvia, where it continues to be a day of importance, with various events being organized. Since its independence from the Soviet Union, Latvia has maintained Labour Day as a public holiday, retaining its focus on workers' rights and welfare.

Labour Day in Latvia is typically marked by peaceful demonstrations, marches, and parades across the country, with workers from various industries joining together in a demonstration of solidarity. People also take it as an opportunity to spend time with family and friends, often enjoying outdoor activities if the weather allows. Despite modern changes in the labour market and a shift towards more digital and flexible working conditions, Latvia continues to celebrate Labour Day as a reminder of the importance of workers' rights and social justice.
