A standard ice hockey game lasts 60 minutes of playing time, divided into three 20-minute periods.
Ever wondered about the clock when watching a fast-paced ice hockey match? Many fans ask, ‘how long does a game of ice hockey last?’ Well, the answer isn’t as simple as just the 60 minutes you see on the scoreboard.
Game time can extend because of stoppages for penalties, goals, and other events, so the actual duration of a game varies. This can make a seemingly simple question a bit more complex.
How Long Does a Game of Ice Hockey Last?
Ever wondered how much time you’d spend cheering during an ice hockey game? It’s not as simple as just a set time like in some other sports. A hockey game is made up of different parts, and sometimes there are extra bits that can make it longer. So, let’s break down the exciting world of hockey time and learn what makes a game tick, time-wise. We will explore a typical game length and the factors that can add or subtract time from the overall clock.
The Standard Game Length: Three Periods of Action
The basic building block of a hockey game is the period. In most professional and major league ice hockey games, like those in the NHL (National Hockey League), there are three periods. Each of these periods is officially 20 minutes long. But this isn’t like a clock that runs straight for 20 minutes.
Here’s the cool part: the clock only runs when the puck is in play. Whenever the whistle blows for a stoppage of play – like a penalty, an offside, or when the puck goes out of play – the clock stops. This means that a 20-minute period of hockey can take much longer than 20 minutes to complete. It could be 30 or more real-time minutes.
So, if we add up the three 20-minute periods, you might think a game lasts 60 minutes. But remember, that’s only the total playing time. We still need to factor in the breaks between periods and any other things that might cause delays.
The Intermissions: Taking a Break
Just like in a school day, there are breaks between the periods, which we call intermissions. These give the players a chance to rest, hydrate, and plan their next move. They also give the Zamboni machine a chance to resurface the ice and make it nice and smooth for the next period of play.
Typically, intermissions are 15 to 18 minutes long. The break between the first and second period will be the same as the break between the second and third period. During these breaks, the players go back to their locker rooms, coaches talk strategies and fans get up for snacks, to stretch out their legs or maybe take a trip to the restroom. These breaks are a crucial part of the flow of a hockey game.
What Happens When Games are Tied? Overtime
Sometimes, after the three periods, teams have scored the same number of goals – a tie! When this happens, most hockey leagues have overtime. Overtime is an extra period to find a winner. How this works can change depending on the league:
Sudden Death Overtime
In many leagues, especially in the playoffs, overtime is played using a “sudden death” format. This means that the first team to score a goal wins the game. This type of overtime is very exciting because it can end the game quickly! The NHL has a form of sudden death overtime in their regular season, but it changes to a sudden death format in the playoffs. Regular season sudden death overtime in the NHL is 5 minutes, but playoff sudden death overtime periods are 20 minutes.
Shootout
In the NHL regular season, if a game is still tied after overtime, it goes to a shootout. In a shootout, each team takes turns having one player try to score against the opposing goalie. If one team scores more goals in the shootout they win the game. In the NHL, overtime in the playoffs is the 20 minute sudden death format described above, and there is no shootout during the playoffs.
Other leagues will often use a sudden-death overtime for both regular season games and playoff games, and they usually will not have a shootout.
Penalties and Stoppages: Time Added On
Remember we said the game clock stops whenever there’s a stoppage in play? There are a lot of things that can stop the clock. Referees call penalties when a player breaks the rules. These can cause delays while the officials determine what happened, and how to punish the infraction. A player has to sit in the penalty box for a set time, and depending on the infraction, they may be in there for two, four, five, or sometimes ten minutes.
Also, whenever a player shoots the puck out of the rink, it results in stoppage time. And even though the game is still running, there may be stoppages for icing. Icing is when a player shoots the puck from behind their own blue line and it travels to the opponent’s goal line without being touched by another player. This rule is meant to reduce stalling. All of these things add extra time to the overall duration of the game.
Different Leagues, Different Rules: Slight Variations
While the basic structure of three 20-minute periods is standard in many major leagues, there can be some slight variations depending on the level of play. For example:
- Youth Hockey: Games for younger kids often have shorter periods, sometimes only 15 minutes long or even less. This is because younger players get tired more quickly. Intermissions can also be shorter for these games.
- International Hockey: International competitions, like the Olympics, follow the same basic three-period format.
- College Hockey: College hockey games will often follow the same structure as the NHL, with three 20-minute periods. However, differences may exist with the overtime procedures.
The Real-Time Clock: How Long Is it Really?
So, if you add up the three 20-minute periods, that’s a total of 60 minutes of playing time. Then you add the two 15-18 minute intermissions, which adds about 30-36 minutes. This alone makes it more like 90-96 minutes, but we haven’t factored in time for penalties, stoppages in play, possible overtime, or shootouts. In reality, most professional ice hockey games usually last around 2 to 2.5 hours. This is the overall time from when the game starts to when the game is officially over, including the stoppages, penalties, and intermissions.
Games that go into overtime will take longer than the average 2 to 2.5 hour span. A game with many penalties will also be a longer game. If a game goes into a long overtime, it could take three hours or more to complete.
Factors Affecting Game Length
Let’s quickly recap the major factors that can change how long a hockey game actually takes:
- Number of Penalties: More penalties mean more stoppages and therefore a longer game.
- Overtime: If a game goes into overtime or a shootout, it will significantly increase the game’s length.
- Play Stoppages: Any time the puck goes out of play, the play is offside, or another type of stoppage occurs, this will increase the length of a game.
- League rules: Differences exist between leagues in regard to the time spent in the penalty box and in overtime.
Average Game Time: A Quick Guide
Here’s a quick table to summarize the time factors in a typical hockey game:
| Element | Time |
|---|---|
| Playing Time (3 periods) | 60 minutes |
| Intermissions (2) | 30-36 minutes |
| Penalties, Stoppages, other delays | Variable (15-45+ minutes) |
| Overtime | Variable (5-20+ minutes, or shootout) |
Keep in mind that these are average timeframes, a game could be longer or shorter. It is always fun to see the game in person, or on TV. Now you have a better idea of what makes the length of a hockey game, and it can give you a better idea of how to plan your time on game day.
Hopefully, this helps to explain the different factors that go into determining the duration of a hockey game. While the basic structure is there, no two games are exactly the same and each one offers a different experience for the viewer and the players. From thrilling overtime periods to tense penalty shootouts, the game is always exciting and interesting to watch!
The Rules of Ice Hockey – EXPLAINED!
Final Thoughts
A standard ice hockey game consists of three 20-minute periods. This excludes stoppages, which commonly add to the game’s total duration. Therefore, the clock stops during penalties, goals, and puck out of play.
Intermissions of 15-18 minutes occur between each period. These breaks allow players rest and regroup. So, the actual time on the clock isn’t the full picture.
Considering these factors, how long does a game of ice hockey last? Usually, a game takes around two and a half to three hours. It is a fast paced sport.
