1may

1 May, or May 1, is the first day of May in the Gregorian calendar. It is observed in many countries with a range of public holidays, celebrations, and cultural events. The date is most widely associated with International Workers' Day, also known as May Day, a day for labor rights demonstrations and workers’ celebrations. The modern observance grew from 19th-century labor movements seeking an eight-hour workday, and in 1889 the Second International proclaimed May 1 as a day of international workers' solidarity.

Public observance varies by country. In many European, Asian, African, and Latin American nations, May 1 is a public holiday or a day of national or local celebration. In some places it is marked with parades, political events, or family gatherings. In the United States and Canada, Labour Day is celebrated on the first Monday of September, and May 1 is not a federal holiday, though some communities hold events or historical commemorations.

Historical notes: May 1 has been associated with several notable events, including the Act of Union 1707 taking effect on 1 May, and the labor movement events around 1886 that helped establish May Day as International Workers' Day. In cultural contexts, May 1 is also linked to spring festivals such as Beltane in parts of Europe.
