Annually observed on May 1st, this global day honors workers’ contributions and labor movements. While most countries declare a national holiday with rallies and cultural events, some nations mark it differently due to historical contexts. The International Labor Organization sets annual themes addressing contemporary workplace challenges, though the 2025 focus remains forthcoming amidst evolving labor landscapes worldwide.

International Labor Day, also referred to as May Day, is celebrated every year on 1st May. This day is celebrated for the remembrance of hardworking and dedicated people around the world. International Labor Day-a.k.a. International Workers’ Day or May Day-has grown into a forceful symbol of solidarity, social justice, and the continuous struggle for workers’ rights. Let’s look at its date, expected theme, and the fascinating variations in its observance worldwide as we count down to International Labor Day 2025.
Labor Day’s history dates to the late 19th-century American labor movement. American workers called for an eight-hour workday on May 1, 1886, when they went on a nationwide strike. The movement came to a turning point in the Haymarket Affair in Chicago when a peaceful rally was marred by violence after someone included a bomb, killing police officers and civilians. This event served as a rallying call for workers’ rights and gave rise to declaring May 1 as International Workers’ Day across most nations.
The initial official International Workers’ Day was celebrated in 1890 in accordance with a resolution by the Second International, which was a federation of socialist and labor parties, to mark the Chicago demonstrations. May Day has since evolved into an International Day of Action, remembrance, and commemoration for the working class.
When is International Labor Day 2025?
International Labor Day 2025 is on Thursday, May 1st. This date has meant a lot since 1889, when the Second International proclaimed May 1st as a day to celebrate the Haymarket Affair in Chicago and to advance the cause of the eight-hour workday. From then on, it has become an international event, celebrated with rallies, parades, speeches, and cultural activities.

Stay tuned: The theme for 2025 will be declared in a few days and is likely to be something that relates to the pressing issues of today’s world facing workers, such as climate action, technological change, or recovery from the pandemic.

Why the Difference?
The reasons for these differences are rooted in history and politics. For example:
United States and Canada: After the Haymarket Affair, authorities moved themselves away from the socialist and anarchist connotations of May Day, opting for a September date.
