Periods are called "sets" in volleyball and instead of being measured by time length they are measured by points. Each set usually goes until one team reaches 25 points, except the fifth set of a game which only goes to 15 points. A team must win 3 out of 5 of these sets in order to win a game (this differs in tournaments).
