Setting up a basketball game clock

Plan periods, breaks, timeouts, overtime, and the shot clock.

A basketball clock setup needs more than a countdown. Decide the number and length of periods, breaks, timeouts, overtime, and whether to use a shot clock before the game starts.

Choose the game format

  • Official competitions commonly use four periods, but period length depends on the league.
  • A casual event might use four 8–10 minute periods or two 10–15 minute halves.
  • Agree on whether the clock stops for each whistle or runs continuously except for selected situations.

Shot clock and timeouts

A 24-second shot clock is common in formal play. Some rules call for a 14-second or 24-second reset after particular possession changes or stoppages. If the event uses a shot clock, assign someone to operate it. Stop the game clock during a timeout and time the timeout separately.
