Last day of summer takes place on September 06 in 2021, which also is marking the federal holiday Labor Day in the United States. This unofficial end of summer is held on the first Monday in September each year. Even though the summer season actually lasts until the Autumnal equinox at the end of September, almost every summer related activity shuts down after Labor Day.
Labor Day therefore is like the real finish line of summer. Americans celebrate the unofficial last day of summer on a three-day weekend to join BBQs or go to the beach for the last time before autumn and winter. The holiday might also be filled with parades, music, and sports as well as family gatherings.
