Tennis

Tennis has the most legible calendar of any sport: the Australian Open in January, Roland-Garros in late May, Wimbledon in late June and the US Open in late August, with the Masters events between them — Indian Wells and Miami in March, Monte-Carlo in April, Madrid and Rome in May, Queen's in June — and the season finals in November. The Grand Slams last a fortnight and their second weeks are the social ones; Wimbledon's is the center of the London season and the US Open's finals weekend closes the New York summer.

Tickets are by ballot, sale or hospitality; the grounds of every Slam are open to anyone with a ground pass, and the qualifying weeks are free or nearly so. Dates are published a year ahead and rarely move.
