Labor Day is a U.S. federal holiday observed on the first Monday in September. It became a federal holiday in 1894 to celebrate workers and their achievements. It has also become the “unofficial”end of summer as by this time schools have reopened and most summer vacations have ended. Also by this time the days (in the northern hemisphere) are starting to get shorter as we get closer to the autumnal equinox. As all fifty states observe the holiday, state and local government offices are closed as well. Banks are closed as are the U.S. financial markets. Most people who work in office jobs get the day off but retail stores do not observe the holiday usually offering special “Labor Day Sales” to draw customers in.
