Labor Day was first celebrated in New York City on Tuesday, September 5, 1882. By 1894, 23 other states had adopted the day of celebration, dedicated to the American workforce. It was signed into law as a national holiday that year by President Grover Cleveland. 

Fun fact: Labor Day is actually older than the U.S. Labor Department itself, by about 20 years.
