When is Labour Day?
In 2026, Labour Day falls on Friday, May 1, 2026. It is classified here as a national public holiday.
History of Labour Day
Labour Day links Argentina to the international May Day tradition of worker solidarity. It honours the people whose work sustains homes, farms, factories, shops, schools, hospitals and the many formal and informal parts of the economy.
Trade unions, social organisations and political movements have made May 1 an important date for both celebration and demands: better wages, safe workplaces, social protections and collective bargaining remain live questions rather than only historical ones.
Law 27,399 lists May 1 as an immovable national holiday. Marches and rallies may be held in major cities, but the day also functions as a family break, particularly when it creates a long autumn weekend.
Argentina’s labour movement has shaped national politics through unions, collective bargaining, social legislation and repeated struggles over working conditions. May Day events therefore speak to current economic life as well as nineteenth-century international labour history. Essential services continue and not every worker receives an uninterrupted break, while applicable labour law governs compensation and substitute rest.
How Labour Day is observed
