General definition and rule of 24-second shot clock
The 24-second shot clock is a digital device that begins at a countdown of 24 seconds and continues until it reaches its final number of 0.
Additionally, the 24-second shot clock rule in the game of basketball requires an offensive team to attempt a field goal within 24 seconds of their current possession.
Typical outcome when 24-second shot clock reaches zero
When the 24-second shot clock reaches zero on the timer, the device will usually sound an alarm, typically in the form of a horn that would also be unique in relation to the scoreboard’s or game clock’s audible sound, which normally consists of an alternative buzzer type of sound.
From that point, if the offensive team in possession of the ball did not attempt a proper field goal, particularly one that made contact with the rim, then that would lead to a penalty for breaking the 24-second shot clock rule, which is a shot clock violation.
Once a shot clock violation occurs, the team that failed to attempt the valid field goal in time would lose possession of the ball via turnover to the opposing team, who would typically receive it at the nearest sideline where the play was stopped but not as close to the baseline as the free throw line extended.
General time when 24-second shot clock starts
In general, the 24-second shot clock starts once a player gains possession of the basketball, which also means that same player’s team is in control of the ball
Afterwards, the offensive player in possession of the ball as well as other offensive teammates on the court would then have 24 seconds to attempt a field goal before the 24-second shot clock reaches zero.
Nevertheless, it should be stated that during a throw-in, also known as an inbound pass, the shot clock starts when the ball comes in legal contact by any player on the court.
In other words, during the throw-in, a player does not necessarily need to gain full control of the ball to start/continue the 24-second shot clock.
Also, after a jump ball or missed free throw, the 24-second shot clock starts or continues again once any player on the court is in control of the ball.
General time when 24-second shot clock stops
Generally speaking, the 24-second shot clock stops when a defensive player is the last to touch the ball and at the same time, the ball goes out of bounds or gets batted into the basket ring from below.
If that happens, the offensive team should receive the ball for a throw-in opportunity but the 24-second shot clock should not reset either.
Essentially, the offensive team would have whatever time was remaining on the shot clock before the defensive team last touched the ball.
However, it should be noted though that if the 24-second shot clock reaches 0 at the same time the defensive team touches the ball last, it would still result in a shot clock violation.
Example of basketball play for 24-second shot clock
This is an example of a basketball play that emphasizes quick hitting actions that are generally designed to produce scoring opportunities near the basket or around perimeter areas of the court, particularly before the 24-second shot clock reaches zero.
Furthermore, each of the offensive players on the diagrams below are generally represented by the standard basketball positions, unless otherwise noted.
In essence, 1 is the point guard; 2 is the shooting guard; 3 is the small forward; 4 is the power forward; 5 is the center.
Part 1
In terms of the setup: 1 is at the top with possession of the ball; 2 occupies the right side low post area; 3 and 4 fill the left side and right side wing areas respectively; 5 occupies the left side low post area.
To begin, 1 passes the ball, represented by the dotted arrow, with 4 as the recipient.
After that, 5 cuts toward the right side of the lane via a cross screen set by 2. At the same time, 3 cuts to the top via an away screen set by 1.
From there, 5 could receive the ball from 4 and quickly score via a layup at the rim.
Alternatively, 3 could receive the ball instead and take a three-point shot if that is open.
If that shot is not available, then 2 can swiftly cut out to the left side corner while 1 and 5 fill the low post areas.
Part 2
Next, while 3 still has control of the ball, 2 cuts through from the left corner to the right side wing area via triple screens set by 1, 5, and 4.
Following that, 2 receives the ball from 3 and promptly takes the open three-point shot.
Otherwise, if the three-pointer is not there, then 2 can utilize their own playmaking ability to produce a field goal attempt for themselves or other teammates prior to the shot clock reaching zero.

Notable leagues/organizations that implement 24-second shot clock
The 24-second shot clock is primarily implemented in professional leagues such as the National Basketball Association, also known as the NBA, the Women’s National Basketball Association, also referred to as the WNBA, as well as within the International Basketball Federation, commonly abbreviated as FIBA.
General functionality of 24-second shot clock when team possession changes with less than 24 seconds in the game
In general, if there are less than 24 seconds remaining on the game clock in a period of play, then the 24-second shot clock should not be active during a change of possession from one team to another.
As a brief example, let’s say that Team A has possession of the ball with 27 seconds remaining on the game clock in a quarter while there are 12 seconds counting down on the shot clock.
Afterwards, let’s say that Team A attempts a field goal four seconds later with 23 seconds remaining on the game clock.
Next, let’s say that Team B secures the ball via a defensive rebound. At that point, Team B is in control of the ball but since there are less than 24 seconds remaining in the period of play, the 24-second shot clock would not be active at that time.
Possible instances when 24-second shot clock could reset to 24 or 14 seconds
This section contains potential instances when the 24-second shot clock could reset to either 24 seconds or 14 seconds, depending on the situation.
Change of possession
The 24-second shot clock could reset to 24 seconds when possession of the ball changes from one team to the other team.
Personal foul or other types of violations during inbound pass in the backcourt
The 24-second shot clock could reset to 24 seconds when a person foul or other types of violations occur during an inbound pass in the backcourt.
Certain types of jump ball situations
The 24-second shot clock could reset to 24 seconds during certain types of jump ball situations that are not the result of a held ball caused by the defensive team.
Flagrant fouls
The 24-second shot clock could reset to 24 seconds when flagrant fouls occur during the basketball game.
Offensive team gains possession of the ball following missed free throw or field goal attempt
The 24-second shot clock could reset to 14 seconds when the offensive team is the first to gain possession of the ball, typically via offensive rebound, after a missed free throw attempt that stays in play or a missed field goal attempt that touches the basket ring.
Offensive team keeps possession of the ball after it goes out of bounds following missed free throw or field goal attempt
The 24-second shot clock could reset to 14 seconds when the offensive team is able to keep possession of the ball after it goes out of bounds following a missed free throw attempt that stays in play or after a missed field goal attempt that touches the basket ring.
Loose ball foul on the defense
The 24-second shot clock could reset to 14 seconds when the defensive team gets called for a loose ball foul during the time of a missed free throw attempt that stays in play or a missed field goal attempt that touches the basket ring.
This applies when, as a result of the loose ball foul, the offensive team is able to execute an inbound pass in their frontcourt.
