An ice hockey game consists of three 20-minute periods each, i.e. 60 minutes of actual play time. This universal structure characterizes this dynamic sport where each second counts. We explain everything you need to know about the timing of a game:
- The exact duration and the breakdown of periods
- Planned breaks and intermissions
- Specificities according to professional leagues
- Rules in case of equality and extensions
- Differences between amateur and professional hockey
Understanding this organization will allow you to better appreciate the tactics and intensity of this spectacular sport.
How many times in a hockey game?
Ice hockey follows a universal rule: three play periods. This structure applies to all the world professional leagues, whether the North American NHL, the French Magnus League, or the European championships.
Each period lasts exactly 20 minutes actual time, which means that the chronometer stops during game interruptions. This particularity distinguishes hockey from many other sports where time continues to pass.
The three-thirds division allows teams to manage their effort and line changes optimally. Players usually rotate from 30 to 45 seconds, making this time organization essential to maintain the intensity of the game.
What is the total duration of an ice hockey game?
Although the actual playing time is 60 minutes (3 x 20 minutes), the actual duration of a game usually extends over 2-3 hours. This difference is explained by several factors:
Frequent gambling stops are a key element. The chronometer freezes during off-games, prohibited clearances (icing), penalties, marked goals, or when the blade exits the limits of the rink. These interruptions add about 40 to 50 minutes to the total time.
Both intermissions of 18 minutes each between periods allow players to recover and teams to adjust their strategy. These breaks include the resurfacing of the ice by the zamboni, an essential operation to maintain optimal playing conditions.
Line changes, although allowed at any time, also generate short stops that accumulate throughout the meeting.
How does every game run?
Each period begins with one central deployment (bully) in the centre of the ice rink. The referee launches the pallet between the two centers trying to get it back for their team.
During the 20 actual minutes, the game is characterized by:
Constant intensity : Players evolve at full speed, alternating offensive and defensive phases with very rapid changes of possession.
Changes on the fly : Unlike other sports, replacements can be performed during the game, creating a constant ballet between the ice and the player bench.
Management of penalties : When a player commits a fault, he or she will serve his or her penalty on the bench of the penalized. His team then evolved into a digital inferiority, creating powerplay situations for the adversary.
Arbitration remains very strict on dangerous contacts, back loads, or anti-sport behaviour. Major misconduct may result in a minimum of 10 minutes exclusion.
Are there breaks between periods?
Two 18 minute intermissions separate the three periods. These strategic breaks serve several essential purposes:
Physical recovery : Players can rehydrate themselves, receive care if necessary, and recover from the intense effort provided. Hockey requires exceptional cardiovascular qualities.
Tactical adjustments : The coaches analyze the 20 minutes that have passed, modify their game lines, and adapt their strategy according to the evolution of the score.
rink maintenance : The zamboni performs a complete resurfacing to remove ice chips and maintain a perfectly smooth surface. This operation lasts about 12 minutes.
Mental preparation : The teams use this time to remotivate, visualize future actions, and maintain their concentration.
What are the rules in case of equality after periods?
When the score remains zero after the three regulatory periods, several options exist depending on the competition:
Regular season NHL : An extension from 5 minutes to 3 to 3 (plus the guards). If equality persists, a shooting session to the goal separates the teams.
In the final phase (play-offs) : Extensions from 20 minutes to 5 to 5 to the gold goal (sudden death). The first goal marks the end of the game, creating maximum tension.
In European hockey : Most leagues apply the NHL system with extension and then shots at the goal. Some championships award bonus points according to the winning mode.
This "sudden death" rule makes extensions particularly spectacular, since each action can be decisive.
Duration and structure of the leagues (NHL, Ligue Magnus...)
| League | Periods | Duration | Intermissions | Extensions |
| NHL | 3 | 20 min | 18 min | 5 min 3v3 + shots at goal |
| Magnus League | 3 | 20 min | 15 min | 5 min 4v4 + shots at goal |
| IIHF | 3 | 20 min | 15 min | 5 min 3v3 + shots at goal |
| KHL | 3 | 20 min | 18 min | 5 min 3v3 + shots at goal |
Variations mainly relate to intermissions and extensions. The NHL favours longer breaks for the spectacle aspect, while the European leagues opt for a more condensed format.
How many periods in amateur or junior hockey?
Amateur and junior hockey generally respects the professional structure with three 20-minute periods. Nevertheless, there are some adaptations:
Junior Hockey (under 18) : Three periods of 20 minutes with intermissions reduced to 12-15 minutes. Contact rules are often relaxed to favour technical learning.
Recreational hockey : Some amateur leagues adopt 15 or 18 minute periods to reduce the total duration of matches and facilitate the organization of tournaments.
Female hockey : Structure identical to male hockey, sometimes with minor adaptations depending on the level of practice.
School hockey : Short formats (2 x 15 minutes) can be used to adapt to the time constraints of the establishments.
Duration of a match with stops and extensions
The actual duration varies considerably depending on the progress of the party:
Standard match : 2h30 to 2h45 including 60 minutes of play, intermissions, and natural stops of the game.
Match with extension : 3am to 3:15am if the extension and the shots to the goal are necessary.
Play-offs match : Potentially 4 hours or more in case of multiple extensions. The record belongs to a 1936 match that lasted more than 6 hours!
Factors influencing duration include the number of penalties (each fault generates stops), contact intensity (more off-game), and possible medical interventions.
Tips for progress with this exercise
For those who want to improve their hockey-specific fitness, we recommend interval training that replicates the game structure:
Working in 20-minute blocks : Alternate high intensity exercises (sprint, plyometry) for 30-45 seconds with 15-20 seconds of active recovery, reproducing line changes.
Development of lactic endurance : Chain exercises to solicit hockey energy systems: repeated sprints, work with loads, proprioceptive exercises.
Simulation of intermissions Use 15-20 minute breaks to work on active recovery, stretching, and mental preparation for the next effort.
Specific reinforcement Focus on the muscles required for hockey (quadriceps, buttocks, trunk stabilizers) with exercises reproducing the technical gestures.
This structured approach will allow you to develop the specific endurance necessary to maintain your performance level over all three periods.
