A professional basketball game typically lasts about 2 to 2.5 hours, including breaks, timeouts, and halftime. The actual playing time is usually 48 minutes in the NBA, divided into four 12-minute quarters. Other leagues, like FIBA (international basketball), have 40-minute games (four 10-minute quarters).
However, the clock stops for fouls, timeouts, and other breaks, so the total duration of the game is longer than the actual playing time. Halftime is generally 15 minutes, and additional time may be added for overtime if the game is tied at the end of regulation. Overtime periods are usually 5 minutes long.
