The first day in "the lovely month of May" (Camelot) is a national holiday in Germany, Austria, and most of Europe. International Workers' Day is observed in many countries around the globe on May 1. But there are other German May customs that reflect the end of winter and the arrival of warmer days.
Oddly, the widespread custom of celebrating Labor Day on the first of May (am ersten Mai) was inspired by events in the United States, one of the few countries that does not observe Labor Day in May! In 1889, a congress of world socialist parties was held in Paris. The attendees, sympathizing with striking workers in Chicago in 1886, voted to support the United States labor movement's demands for an 8-hour day. They selected May 1, 1890 as a day of commemoration for the Chicago strikers. In many countries around the world May 1 became an official holiday called Labor Day—but not in the U.S., where that holiday is observed on the first Monday in September. Historically the holiday has had special importance in socialist and communist countries, which is one reason it is not observed in May in America. The U.S. federal holiday was first observed in 1894. Canadians also have observed their Labor Day since
