A typical hockey game, at the professional level, lasts about two and a half hours in total, including stoppages and intermissions. The game is divided into three periods, each lasting twenty minutes of actual playtime. However, it is important to note that the clock stops for various reasons, such as penalties, goals, and injuries, meaning that the actual gameplay can take considerably longer in real time. Between the first and second periods, and the second and third periods, there are intermissions that usually last around fifteen to eighteen minutes. This structure allows for team strategy adjustments and provides players some rest. If the game is tied at the end of the three periods, overtime may be played, adding even more time to the overall duration.
