A shot clock is a countdown timer used in a variety of games and sports, proving a set amount of time that a team may possess the object of play before attempting to score a goal. Shot clocks are used in several sports including basketball, water polo, lacrosse, poker, ringette, korfball, tennis, ten-pin bowling, and various cue sports. It is analogous with the play clock used in American and Canadian football, and the pitch clock used in baseball. This article deals chiefly with the shot clock used in basketball.
At most professional and collegiate basketball courts the shot clock is displayed to the players and spectators in large red numerals below the game clock on a display mounted atop each backboard. In some collegiate and amateur facilities this display might be located on the floor or mounted to a wall behind the end line. A shot clock is used in conjunction with a game clock but is distinct from the game clock which displays the time remaining in the period of play. 076b4e4f54
