Overview

International Workers' Day, often called Labour Day, celebrates the achievements and contributions of working people. Most countries observe it on 1 May in connection with the labour movement's fight for the eight-hour workday, while the United States and Canada instead mark Labour Day on the first Monday of September, a tradition with separate 19th-century origins.

What It Is

Where it falls in early September, Labour Day marks the unofficial end of summer with a public holiday, parades, and long weekends. Many workers get the day off, and communities in Canada and the United States hold parades honoring organized labour, a tradition that traces back to 19th-century demonstrations in Toronto and New York. In places observing the 1 May date instead, the day typically features rallies, marches, and public events organized around labour and workers' rights.

Why It Matters

The holiday grew out of the 19th-century labour movement's campaign for an eight-hour day: eight hours for work, eight hours for recreation, and eight hours for rest. Internationally, 1 May was chosen to commemorate the 1886 general strike that culminated in Chicago's Haymarket affair. Separately, Canada's Labour Day traces to an 1872 Toronto demonstration supporting striking printers, which led directly to the Trade Union Act legalizing unions, and to a large 1882 labour parade that inspired similar September parades across North America. Both traditions mark the same underlying struggle for workers' rights and dignified working conditions, even though they developed independently and settled on different calendar dates.
