When I first started watching hockey, I couldn’t help but wonder how the game was structured. It’s fast-paced, intense, and full of action, but what about the timing? Unlike sports with halves or quarters, hockey has its own unique setup that might surprise you if you’re new to the game.
If you’ve ever found yourself asking how many periods there are in hockey or why they’re divided the way they are, you’re not alone. It’s one of those questions that pops up when you’re trying to make sense of the sport. Let me break it down for you so you’ll know exactly what to expect the next time you tune in.
Understanding The Basics Of Hockey Periods
Hockey games consist of three regulation periods. Each period lasts 20 minutes of game time, making the total standard duration 60 minutes. The clock stops for penalties, goals, and other interruptions, so games usually take longer in real time.
Between each period, there’s an intermission. These intermissions last 15-20 minutes, giving players time to rest and teams a chance to adjust strategies.
If the score is tied at the end of the third period, overtime rules come into play. In most leagues, including the NHL, a sudden-death overtime period is played to determine the winner.
How Many Periods Are There In Hockey?

Hockey has a unique structure compared to many other sports. Professional games include three periods, each lasting 20 minutes of play.
Standard Rules In Professional Hockey
In professional hockey leagues like the NHL, there are three periods of regulation time. Each period is 20 minutes long, with intermissions of 15-20 minutes between them. The game clock stops during interruptions, such as goals, penalties, and other play stoppages, so games often take longer in real time.
Overtime is played if the score is tied at the end of the third period. In regular season NHL games, this involves a five-minute sudden-death period, followed by a shootout if necessary. Playoff games, however, use 20-minute overtime periods until a winner is determined.
Variations In Recreational And Amateur Hockey
Recreational and amateur hockey leagues may follow different formats. Some games feature shorter periods, such as 15 or 10 minutes, depending on the league or rink schedule. In youth hockey, two-period games are common, often with each period lasting 20-25 minutes of running time. Overtime rules can also vary, with some leagues opting for shorter sudden-death overtime or directly deciding games through shootouts.
How Long Is Each Hockey Period?

Each hockey period in a standard game lasts 20 minutes of playtime. However, interruptions like penalties and goals stop the game clock, making the actual time longer.
Professional Hockey Period Duration
In leagues like the NHL, games consist of three regulation periods of 20 minutes each. These periods are played with a running clock, except when play stops due to rules such as icing, penalties, or scoring. Between periods, there are intermissions of 15-20 minutes. The 20-minute duration applies to most professional and international leagues.
Overtime And Shootouts
If a game ends in a tie score after three periods, overtime steps in to determine a winner. Regular-season NHL games feature a five-minute, sudden-death overtime played with three skaters and one goalie per team. If no team scores during this period, a shootout follows. Playoff games use a different format, adding 20-minute sudden-death overtime periods until a team scores. Other leagues may alter the overtime structure, sometimes including shorter overtime periods or progressing directly to a shootout.
The History Behind Hockey Periods

Hockey’s three-period structure originated in the early 20th century. Initially, games were played in two halves, similar to sports like soccer. However, players and officials found extended halves challenging due to the physical demands and ice quality deterioration.
In 1910, the National Hockey Association (NHA) decided to divide games into three 20-minute periods. This adjustment improved ice maintenance during intermissions and gave players time to recuperate. The change also enhanced the overall pace and strategy of the game.
Over time, this format became the standard for professional and international leagues. The three-period system remains a key aspect of hockey’s identity, balancing physical endurance with tactical gameplay.
Why Periods Are Divided Into Three In Professional Hockey
The three-period format enhances the game’s quality by balancing action and rest. Players exert intense energy during shifts, which usually last 45-90 seconds. Dividing the game into three periods ensures players can recover and maintain peak performance throughout the game.
Ice maintenance significantly impacts game quality. With two intermissions between periods, crews can resurface the rink twice, ensuring consistent ice conditions for smoother gameplay and fewer safety concerns.
Strategic adjustments play a crucial role in a fast-paced sport like hockey. Ending periods allows teams to regroup, analyze opponents’ strategies, and make tactical changes, improving overall competitiveness.
This format originates from early 20th-century efforts to improve the game. Halves made ice surfaces deteriorate faster, while three shorter periods allowed better maintenance and player endurance, shaping modern hockey standards.
Conclusion
Hockey’s three-period structure is such a fascinating blend of strategy, endurance, and tradition. It’s one of those unique aspects that sets the game apart and keeps it exciting for players and fans alike. Whether you’re watching a professional NHL game or a local amateur match, understanding how the periods work adds so much more to the experience.
I hope this breakdown helps you feel more confident the next time you’re watching or discussing hockey. There’s so much to appreciate about the sport, and knowing these details makes it even more enjoyable to follow.
