Grand Slam tournaments are among the small number of events that last two weeks, the others being the Indian Wells Masters and the Miami Masters. In the event of a rain delay, darkness or other external conditions halting play, the match is resumed at a later time, with the same score as at the time of the delay, and the players at the same end of the court when rain halted play, or at the same position north or south if play is resumed on a different court.

The referee, who is usually located off the court, is the final authority about tennis rules. Andre Agassi chose to skip Wimbledon from through citing the event's traditionalism, particularly its "predominantly white" dress code.
