A hockey game features three 20-minute periods, adding up to 60 minutes of regulation play. With two intermissions lasting around 15-18 minutes each, plus stoppages, timeouts, and possible overtime, the total duration typically ranges from 2 to 2.5 hours. In playoff scenarios, games can extend significantly due to unlimited sudden-death overtime until a winning goal is scored.
