Since 1987, the US Open has been chronologically the fourth and final tennis major comprising the Grand Slam each year; the other three are the Australian Open, French Open and Wimbledon. It is held annually in August and September over a two-week period (the weeks before and after Labor Day weekend). The main tournament consists of five different event championships: men's and women's singles, men's and women's doubles, and mixed doubles, with additional tournaments for senior, junior, and wheelchair players. Since 1978, the tournament has been played on acrylic hard courts at the USTA Billie Jean King National Tennis Center at Flushing Meadows-Corona Park in Queens, New York City.
The US Open has tiebreaks in every set, including the last set. The other three Grand Slam tournaments have tiebreaks in every set other than the last set (i.e. the fifth set for men and third set for women), and therefore their last set continues indefinitely until a two-game lead is reached. The DecoTurf surface at the US Open is a fast surface, having slightly less friction and producing a lower bounce compared to other hard courts (most notably the Rebound Ace surface formerly used at the Australian Open). For this reason, many serve-and-volley players have found success at the US Open.
The main court is located at the 22,547-seat Arthur Ashe Stadium, opened in 1997. It is named after Arthur Ashe, the African American tennis player who won the men's final of the inaugural US Open in 1968. The next largest court is Louis Armstrong Stadium, opened in 1978, extensively renovated from the original Singer Bowl. It was the main stadium from 1978–96, and its peak capacity neared 18,000 seats, but was reduced to 10,200 after the opening of Arthur Ashe Stadium. The third largest court is the 6,000-seat Grandstand Stadium, attached to the Louis Armstrong Stadium. Sidecourts 4, 7, and 11 each have a seating capacity of over 1,000.
