What are the four Grand Slams in tennis?
The four Grand Slams are the Australian Open, the French Open (Roland Garros), Wimbledon and the US Open. They are tennis's biggest tournaments.
The season begins with the Australian Open in Melbourne in January, played on hard courts. The French Open in Paris follows in May and June on red clay, then Wimbledon in London in late June and July on grass. The US Open in New York ends the Grand Slam season in late August and September on hard courts.
Each tournament has singles events with 128 players in the main draw, plus doubles and mixed doubles. Men's singles matches are best of five sets, and women's best of three.
What is a calendar Grand Slam?
Winning all four in the same year is called a calendar Grand Slam. Only a few players have done it in singles, including Rod Laver in 1962 and 1969 and Steffi Graf in 1988. Graf also won Olympic gold that year, a feat called the Golden Slam.

Wimbledon is the oldest Grand Slam, first held in 1877, and the only one still played on grass.
