Labor Day is called the "unofficial end of summer" because it marks the end of the
U.S. culture's nominal summer season. Of the 7% of Americans who take two-week vacations, many take their
vacations during the two weeks ending Labor Day weekend. Many fall activities, such as school and sports (particularly
football), begin about this time. In the United States, many school districts resume classes around the Labor Day holiday weekend (see
First day of school). Some begin the week before, making Labor Day weekend the first three-day weekend of the school calendar, while others begin the Tuesday following Labor Day. Many districts across the Midwest are opting to begin school after Labor Day. In the U.S. state of
Virginia, the
amusement park industry successfully lobbied for legislation requiring most school districts in the state to have their first day of school after Labor Day, in order to give families another weekend to visit amusement parks in the state. The relevant statute has been nicknamed the "
Kings Dominion law" after one such park. This law was repealed in 2019. In the U.S. state of
Minnesota, the
State Fair ends on Labor Day. Under state law, public schools normally do not begin until after the holiday. One reason given for this timing was to allow time for schoolchildren to show
4-H projects at the Fair. In U.S. sports, Labor Day weekend marks the beginning of many fall sports.
National Collegiate Athletic Association (NCAA) teams usually play their first games that weekend, and the
National Football League (NFL) traditionally play their
kickoff game the Thursday following Labor Day. The
Southern 500 NASCAR auto race has been held on Labor Day weekend at
Darlington Raceway in
Darlington, South Carolina from 1950 to 2003 and since 2015. At
Indianapolis Raceway Park, the
National Hot Rod Association hold their finals of the
NHRA U.S. Nationals drag race that weekend. Labor Day is the middle point between weeks one and two of the
U.S. Open tennis championships, held in
Flushing Meadows, New York. In the fashion world, Labor Day was once considered the last day it was acceptable to wear white or
seersucker. The source of the tradition lies in part with the migration of wealthy 19th century New Yorkers back from their summer-home
Newport Mansions and accompanying change back from summer clothes. The traditional last day to wear
straw hats moved from around Labor Day (September 1) to September 15. In 1922, the
Straw Hat Riot broke out due to gangs snatching the hats of men violating this rule in New York City. The unofficial beginning of summer, and the summer fashion season in the United States, is
Memorial Day. In the 2020s, some people have approved of wearing white year-round. In Washington, one popular event is the Labor Day Concert at the U.S. Capitol featuring the
National Symphony Orchestra with free attendance. ==Observance dates (1971–2037)==
