Have you ever wondered just how long a hockey game takes when you are planning your evening around watching your favorite team? Hockey matches are usually 3 to 2.5 hours long, but the game only lasts 60 minutes in three 20-minute shifts..
The game itself takes around 2.5 to 3 hours in total, with 3 20-minute periods (60 minutes of play), two 17-18 minutes intermissions, timeouts, penalties, and possible overtime. There are many reasons why the clock stops during play.

The Problem: Hockey Time Confusion
You look at the TV and note that the Bruins vs Rangers is at 7:00 pm. So the game is over at about 8:00 PM, right? Wrong. At 10:00 PM, you will still be sitting and asking yourself when this will end.
Hockey’s timing system confuses newcomers more than any other major sport. Unlike basketball or football, where you can estimate the end time, hockey games stretch longer because of stops, penalties, and overtime possibilities.
Here’s what actually happens during those “60 minutes” of hockey that somehow take three hours to complete.
How Many Hockey Periods Are in a Game?
There are only three periods in hockey games, and each period has 20 minutes of playing time. This has been the same structure since the inception of professional hockey.
Why Three Periods Instead of Two Halves?
Hockey chose three periods for practical reasons. The ice surface needs regular maintenance, and players need more frequent breaks due to the physical intensity. Three shorter periods also create more excitement with fresh starts and momentum shifts.
Period Length Breakdown
Each period contains:
- 20 minutes of playing time
- Multiple clock stoppages
- Penalty time that extends the period
- TV timeouts for broadcasts
The 20 minute clock will be in operation only when a puck is in play. The clock is stopped with every whistle, and this is why it could take 35-40 minutes in real time to complete a period.
How Long Does a Hockey Game Last: The Real Timeline
Official Playing Time: 60 Minutes
Officially, each game of hockey is one hour long. Three sessions of 20 minutes will amount to 60 minutes. But that is only the tip of the iceberg.
Actual Game Duration: 2.5 to 3 Hours
Here’s where those extra hours come from:
Intermissions Between Periods
- First intermission: 17-18 minutes
- Second intermission: 17-18 minutes
- Players rest, ice gets cleaned, and TV shows commercials
Clock Stoppages During Play
- Penalties and power plays
- Offsides and icing calls
- Goals and celebrations
- Injuries and equipment repairs
- Puck going out of bounds
TV Timeouts
- Commercial breaks during each period
- Usually 2-3 timeouts per period
- Each timeout lasts 1-2 minutes
Breaking Down Hockey Game Components

- 20 minutes of playing time
- Takes about 35 minutes real time
- Multiple stops for penalties, offsides, and TV timeouts
7:40-7:58 PM – First Intermission

8:53-9:30 PM – Third Period
- Final 20 minutes
- Fastest period due to urgency
- Fewer stoppages as teams push for goals
9:30 PM – Game Ends (Maybe)
- If tied, the game goes to overtime

- Victory celebrations and interviews
Overtime and Shootout Duration
Regular Season Overtime
- 3-on-3 sudden death
- Lasts a maximum of 5 minutes
- First goal wins
- Adds 10-15 minutes to total game time
Shootout
- Happens if overtime ends scoreless
- Best of three rounds initially
- Can go to sudden death rounds
- Adds 5-10 minutes to the game
Playoff Overtime
- Full 5-on-5 hockey
- 20-minute sudden death periods
- Continues until someone scores
- Can add hours to playoff games
Factors That Make Hockey Games Longer
Penalties and Power Plays
Penalties stop the clock and extend periods significantly. A major penalty keeps one team short-handed for five full minutes of playing time. With clock stoppages, this could take 8-10 minutes of real time.
Fighting and Scrums
Though less common now, fights and post-whistle scrums add time. Referees need to sort out penalties, and TV loves to replay the action during extended stoppages.
Injury Timeouts
Serious injuries can stop play for 5-10 minutes while the medical staff attends to the players. The clock stays stopped during these delays.
Equipment Problems
The loose helmets, broken sticks, and goalie equipment cause mini-stoppages during the game. All these little delays combine to more than 60 minutes.
Video Reviews
The review of goals and the challenges by the coach may require 2-5 minutes to complete. The footage is viewed by referees to confirm the goals, offside and goaltender interference.
Different Hockey Leagues and Their Durations
NHL (National Hockey League)
Standard duration as described above. Most predictable timing among professional leagues.
College Hockey
Similar structure but with some differences:
- Longer intermissions (20 minutes)
- Different overtime rules
- Games often run 3+ hours
Junior Hockey
- Three 20-minute periods
- Shorter intermissions (15 minutes)
- Less TV commercial time
- Usually 2.5 hours total
International Hockey
- IIHF rules vary slightly
- Longer overtime periods in tournaments
- Different penalty systems affect timing
Tips for Planning Around Hockey Games
Arriving at the Arena
Get there 30 minutes before the listed start time. Parking, security lines, and finding seats take longer than you think.
Watching at Home
Don’t plan important activities right after the scheduled end time. Always add at least 30 minutes buffer for overtime possibilities.
Recording Games
Set your DVR to record an extra hour beyond the scheduled end time. Nothing worse than missing overtime goals because your recording stopped.
Why Hockey Takes Longer Than Other Sports
Compared to Basketball
Basketball has a running clock for most of the game. Hockey stops the clock for everything, making periods drag longer than expected.
Compared to Baseball
Baseball has no time limit but consistent pacing. Hockey’s constant stops and starts make timing unpredictable.
Compared to Football
Football builds stoppages into the broadcast schedule. Hockey’s natural stoppages are harder to predict and control.
Frequently Asked Questions About Hockey Game Duration
How Long is Each Hockey Period?
Each hockey period lasts exactly 20 minutes of playing time. However, real-time duration ranges from 30-40 minutes due to clock stoppages for penalties, offsides, goals, and TV timeouts.
How Many Hockey Periods Are in a Professional Game?
Professional hockey games have three periods of 20 minutes each. This applies to NHL, AHL, and most other professional leagues worldwide.
What’s the Longest Hockey Game Ever Played?
The longest NHL game lasted 176 minutes and 30 seconds of playing time (nearly three full games worth). The Detroit Red Wings beat the Montreal Maroons 1-0 in 1936 after six overtime periods.
Do Hockey Games Ever End Early?
No, hockey games never end before the full 60 minutes unless abandoned due to extreme circumstances like arena emergencies or severe weather affecting outdoor games.
How Long Are Hockey Intermissions?
NHL intermissions last 17-18 minutes between each period. This gives players time to rest while arena crews clean and maintain the ice surface.
Why Do Hockey Clocks Stop So Much?
The clock stops for penalties, offsides, icing, goals, injuries, puck out of play, and TV timeouts. This ensures teams get full 20-minute periods of actual playing time.
How Long Does Overtime Last in Hockey?
Regular-season NHL overtime lasts 5 minutes, with a maximum of 3-on-3 sudden death. Playoff overtime uses full 20-minute sudden-death periods until someone scores.
Can Hockey Games End in Ties?
Not in the NHL. Regular-season games tied after overtime go to a shootout. Playoff games continue with 20-minute sudden-death periods until there’s a winner.
Making the Most of Hockey Game Length
Embrace the Social Aspect
Hockey’s length makes it perfect for social viewing. Use intermissions to grab food, discuss strategy, and connect with other fans.
Learn to Read Game Flow
Experienced fans can predict when periods will end faster. Late in close games, there are fewer stoppages as teams avoid penalties.
Plan Your Snacks
Two intermissions mean two perfect snack opportunities. Many fans time their concession runs with the breaks.
Conclusion: Hockey Time is Different
Knowledge of the duration of the hockey games allows you to organize your watching schedules. You can spend those three hours with your head on the action, and it can be a drag when you spend the time seeing what the clock says.
The 2.5-3-hour playing time with a 60-minute game gives hockey another rhythm that distinguishes the sport from the rest. Intermissions create tension, and repetitive clock stops keep the tension at an even footing in every period.
When somebody tells you how many periods are in hockey, or how long the game is, you can tell them both the easy version (three 20-minute periods) and the hard version (three hours of your evening).
No matter your level of expertise (a new fan who is learning the ropes or just trying to fit games in with your personal schedule), it is important to remember that hockey runs on its schedule. Relish the pace and the breaks and never end up having less than half a minute left to hopeful overtime.
