The main show courts, Centre Court and No. 1 Court, are normally used for only two weeks a year, during the Championships, but play can extend into a third week in exceptional circumstances. The remaining 17 courts are regularly used for other events hosted by the club. The show courts were in action for the second time in three months in 2012 as Wimbledon hosted the tennis events of the 2012 Olympic Games. One of the show courts is also used for home ties of the GB teams in the Davis Cup on occasions.
