The one-line summary

May Day on May 1 is observed worldwide as both International Workers Day and a traditional spring festival. Public holiday in most countries outside the United States.

The Haymarket affair

May Day's modern political weight derives from the Haymarket affair in Chicago, Illinois. On May 1, 1886, US unions began a national campaign for the eight-hour workday. The campaign led to rallies on May 3 and a large demonstration on May 4 in Haymarket Square; as police tried to disperse the crowd, an unknown person threw a bomb, killing one officer and wounding several. The police then opened fire on the crowd; seven officers and four civilians died in the incident. Eight anarchists were tried; four were hanged (November 11, 1887). The affair became a defining event for the international labour movement.

In 1889 the Second International, meeting in Paris, proclaimed May 1 as International Workers Day in memory of the Haymarket martyrs. The first international May Day was observed on May 1, 1890. The choice of May 1 was politically symbolic: it aligned the new labour holiday with the spring season of renewal and with the dates of the Haymarket campaign itself.

Origin

May Day on May 1 is observed worldwide as both International Workers Day (a labour movement commemoration since 1890) and a traditional spring festival (May Day / Beltane in Celtic cultures, Maifest in Germanic cultures). The earlier forms of the festival predate the labour observance by centuries.

Pre-industrial May Day traditions

May Day traditions in Europe predate the modern labour observance by centuries. The maypole: a tall pole is erected in a village green, around which dancers weave ribbons in complex patterns. May Day baskets: small baskets of flowers or sweets are left anonymously at neighbours' doors. The May Queen: a girl chosen to preside over village May Day celebrations. Morris dancing: traditional English folk dance. The dew gathering: in some Celtic traditions, washing one's face in May dew on May Day morning for beauty. The Celtic Beltane: a fire festival observed on May Eve (April 30) in Ireland and Scotland, with bonfires and cattle being driven between two bonfires for purification.

The Germanic Maifest, traditionally observed on May 1, is associated with the maypole (Maibaum), the crowning of a May Queen (Maikönigin), and the raising of May arches over village gates. The tradition is strongest in Bavaria, Baden-Württemberg, and Austria; many German Biergartens open for the season on May 1.

How May Day is observed

In labour-tradition countries (Germany, France, Italy, Russia, China, India, Bangladesh), the day is marked by large union rallies, often in city centres. In spring-tradition countries (UK, Ireland, Scandinavia), the day is more modest and maypole-centred. In the United States, May Day is observed as a working day (except in some states that have moved the Labour Day observance to early May informally); the principal US May Day activity is the immigration-rights "A Day Without an Immigrant" boycott, which has been organised since 2006.

May Day is a public holiday in Germany (Tag der Arbeit or Maifeiertag), France (Fête du Travail), Italy (Festa del Lavoro), Spain, Portugal, Austria, Switzerland, Belgium, Netherlands, Poland, Greece, Russia, China, India, Bangladesh, and most of Latin America. It is not a federal public holiday in the United States (where Labor Day is observed in September), nor in Canada (where Labour Day is also in September), nor in the UK (where the May Day bank holiday is the first Monday of May, not May 1 itself).

The UK versus continental calendar

In the UK, the May Day bank holiday is the first Monday of May (the Early May Bank Holiday, established by the Banking and Financial Dealings Act 1971). The UK specifically did not move to a May 1 observance to avoid aligning with the Soviet-aligned labour tradition. The distinction persists today, with the UK's Early May Bank Holiday on the first Monday of May and most continental European countries observing the strict May 1 date.

Where it is contested

Discussions focus on three areas. First, the political symbolism of May 1 has produced polarised celebrations in countries with strong leftist traditions (the annual Russian Communist Party march; French CGT rallies). Second, the relationship between the labour-tradition May Day and the spring-tradition May Day has produced different emphases in different countries. Third, the use of May 1 by immigration rights movements in the US has generated debate about whether May 1 should be a federal holiday there.

In other countries

May Day is observed worldwide. In Latin America, May 1 was historically suppressed in countries under military rule (Argentina, Chile, Brazil) and re-emerged as a principal public holiday with the return to civilian rule. In Russia, May 1 is observed as the Spring and Labour Day (Prazdnik Vesny i Truda) since the Soviet calendar reform of 1991. In Cuba, May 1 is celebrated with major demonstrations in Havana's Plaza de la Revolución.

History of May Day

May 1 is observed as a public holiday in many countries as International Workers' Day, commemorating the 1886 Haymarket affair in Chicago. The Second International declared May 1 as International Workers' Day in 1889. The day has been a focal point for labour movements worldwide.

In parallel, May Day has ancient European roots as a spring festival, marked by maypole dancing, May Queen crowning, and gatherings. The two traditions often overlap in modern celebrations.

How it is observed

International Workers' Day is a public holiday in dozens of countries, including China, Russia, most European countries, and many others. The day is marked by rallies, marches, speeches, and cultural events organised by trade unions and labour movements.

May Day as a spring festival is observed in the UK, Germany, France, Finland, Sweden, and other countries with maypole dancing, traditional flower crowns, and community events. The traditions often merge in modern celebrations.

Preguntas frecuentes

When is May Day 2026?

Friday, May 1, 2026. May Day is fixed at May 1 every year. It is a public holiday in most countries outside the United States; the US observes Labor Day on the first Monday of September instead.

Why is May 1 International Workers Day?

May 1 was chosen as International Workers Day at the 1889 congress of the Second International in Paris, to commemorate the Haymarket affair in Chicago (May 4, 1886), when a labour demonstration turned violent. The first international May Day was observed on May 1, 1890. The date also has older labour roots: on May 1, 1886, US unions began campaigning for the eight-hour workday; the campaign led to the Haymarket violence. By 1900, May Day was the central annual demonstration of the international labour movement.

Is May Day a public holiday?

Yes in most countries. May Day is a gesetzlicher Feiertag in Germany (where it is called Tag der Arbeit or Maifeiertag), France (Fete du Travail), Italy (Festa del Lavoro), Spain, Portugal, Austria, Switzerland, Belgium, Netherlands, Poland, Greece, Russia, China, India, Bangladesh, and most of Latin America. It is not a federal public holiday in the United States (where Labor Day is observed in September), nor in Canada (where Labour Day is also in September), nor in the UK (where the May Day bank holiday is the first Monday of May, not May 1 itself).

Why does the UK May Day fall on the first Monday of May instead of May 1?

In the UK, the May Day bank holiday is the first Monday of May, not May 1 itself. In 2026 the UK May Day bank holiday falls on Monday, May 4. In most other countries, May Day is strictly May 1. The distinction matters because the May 1 date preserves the historical link to the Haymarket affair and the Second International; the floating Monday bank holiday was chosen to give workers a long weekend.

What is the labour tradition of May Day?

On May 1, workers and unions around the world hold rallies, marches, and demonstrations. Major annual May Day events include Beijing (where the government organizes large rallies), Moscow (where the Communist Party traditionally marches), Berlin (where the DGB trade union federation organizes a major rally), Paris (where the CGT union traditionally marches), and Manila. In countries with weaker labour traditions, May Day is observed as a public holiday but with limited public demonstration.
