Labour Day or Labor Day is an annual holiday celebrated all over the world that resulted from the labour union movement, to celebrate the economic and social achievements of workers. The majority of countries celebrate Labour Day on May 1, and it is popularly known as May Day and International Workers‘ Day, while some celebrate on the first Monday of September.
The celebration of Labour Day has its origins in the Eight-hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest.
After the traditional dance into the May last night; today the masses gathered to demonstrate in Berlin-Kreuzberg and other major cities. Like every year the extremely right and left orientated political groups come to demonstrate. This year the Nazis seem to be especially outnumbered. Their routs have been shortened in many cities, due to the large numbers of anti-Nazi demonstrators.
The probably most impressive picture of the day was twittered by Matthias, who uploaded it for a friend:
