how long is the ball in play in soccer
Association football A standard adult football match consists of two halves of 45 minutes each. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time.[94] The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called additional time in FIFA documents,[95][96] but is most commonly referred to as stoppage time or injury time, while lost time can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. Stoppage time does not fully compensate for the time in which the ball is out of play, and a 90-minute game typically involves about an hour of "effective playing time".[97] The referee alone signals the end of the match. In matches where a fourth official is appointed, towards the end of the half the referee signals how many minutes of stoppage time he intends to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee.[94] Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa. Trailing 1–0 and with just two minutes remaining, Stoke were awarded a penalty. Villa's goalkeeper kicked the ball out of the ground, and by the time the ball had been recovered, the 90 minutes had elapsed and the game was over.[98] The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed, thus no game shall end with a penalty to be taken.[99]
FIFA World Cup The current format of the competition involves a qualification phase, which currently takes place over the preceding three years, to determine which teams qualify for the tournament phase, which is often called the World Cup Finals. After this, 32 teams, including the automatically qualifying host nation(s), compete in the tournament phase for the title at venues within the host nation(s) over a period of about a month.
Basketball Games are played in four quarters of 10 (FIBA)[34] or 12 minutes (NBA).[35] College men's games use two 20-minute halves,[36] college women's games use 10-minute quarters,[37] and United States high school varsity games use 8 minute quarters.[38] 15 minutes are allowed for a half-time break under FIBA, NBA, and NCAA rules[36][39][40] and 10 minutes in United States high schools.[38] Overtime periods are five minutes in length[36][41][42] except for high school, which is four minutes in length.[38] Teams exchange baskets for the second half. The time allowed is actual playing time; the clock is stopped while the play is not active. Therefore, games generally take much longer to complete than the allotted game time, typically about two hours.
Rugby union Games are divided into 40-minute halves, with a break in the middle.[63] The sides exchange ends of the field after the half-time break.[63] Stoppages for injury or to allow the referee to take disciplinary action do not count as part of the playing time, so that the elapsed time is usually longer than 80 minutes.[63] The referee is responsible for keeping time, even when—as in many professional tournaments—he is assisted by an official time-keeper.[63] If time expires while the ball is in play, the game continues until the ball is "dead", and only then will the referee blow the whistle to signal half-time or full-time; but if the referee awards a penalty or free-kick, the game continues.[63]
