The Grand Slam tournaments, also called majors, are the four most important annual tennis events. They offer the most ranking points, prize money, public and media attention, the greatest strength and size of field, and greater number of "best of" sets for men, which is 5. The Grand Slam itinerary consists of the Australian Open in mid January, the French Open from around late May to early June, Wimbledon in June–July, and the US Open in August–September. Each tournament is played over a two-week period. The Australian and United States tournaments are played on hard courts, the French on clay, and Wimbledon on grass. Wimbledon is the oldest, founded in 1877, followed by the US in 1881, the French in 1891, and the Australian in 1905. However the French Championships was not considered a major before 1924–25, when all four became designated Grand Slam tournaments. Skipping majors—especially the Australian Open because of the remoteness, the inconvenient dates and the low prize money—was not unusual before 1982.
