The first day of May has been observed as a holiday since ancient times. Spring festivals, maypoles and maying are still common, but the political importance of May Day has grown since the 1880s, when it became a workers' day in the US. Now widely observed in countries as a workers' holiday or as a Labor Day. (Bermuda, Canada and the US observe Labor Day in September.) In most European countries, when May Day falls on Saturday or Sunday, the Monday following is observed as a holiday, with bank and store closings, parades and other festivities.
