Why is Labor Day celebrated in September in the United States?
In most parts of the world, Labour Day is traditionally celebrated on May 1st and strongly associated with labour unions. Demonstrations, manifestations and political speeches are common. In northern Europe, May 1st also have an older significance as a holiday since various spring celebrations centred on this early spring date in traditional rural communities. In the United States and neighbouring Canada, Labor Day is instead celebrated on the first Monday of September and marks the summer vacation season rather than commemorating labour history.
