Hockey is played in periods, however a common question is: how many quarters or halves are in a hockey game?
If you are new to hockey one of the first things you will want to know is how the actual structure of the game works. Hockey is different from football, basketball and soccer in how it is timed and structured, and has periods and not quarters or halves.
How many periods are there in hockey? In a game of ice hockey is divided into three periods of twenty minutes each with two fifteen minute intermissions in-between the periods. If the game is tied at the end of three periods in the regular season, it is followed by a 5 minute overtime and then (possibly) a shootout.
Whereas, in the playoffs if the game is tied at the end of regulation additional periods of 20 minutes each with intermissions in between will be added until someone scores, which immediately ends the game.
Let’s take a look at why hockey has periods and not halves or quarters (with a few exceptions), and the typical flow of how a game go in real time.Embed from Getty Images
Why three periods and not two halves?
Hockey has not always been played in three 20-minute periods. Originally, the game started with two 30-minute halves with an intermission in-between. It is hard to know when the switch from two halves to three periods was made, but likely in the early 1900s.
The concept of three periods was an innovation that was part of the NHA, a competitor and predecessor to the NHL.
The reason the change was made from two halves to three periods, and why it still is kept today, has everything to do with the quality of the ice.
During the intermission (the 15 minutes of time between the periods), the ice is resurfaced by a machine called a zamboni. The resurfacing of the ice allows any small holes, skate marks, or snow that has been piled up to be fixed. After the resurfacing of the ice, the ice quality is greatly improved and, ideally, the ice is fresh and new.Embed from Getty Images
When hockey was played in two 30-minute halves, there was too much wear and tear on the ice. It was determined that the hockey players skating on the ice were just too hard on the ice and the quality of the ice by the end of the half was becoming too poor to play.
If you are watching on tv or are at a game, you can spot poor quality ice by watching to see if the puck is ‘bouncing’. The puck will have a harder time staying flat on the ice and as the players pass and shoot the puck you can see that the puck does not stay still. This creates difficulty for the players and a poorer quality of game.
Does hockey ever have two halves or four quarters? A couple of exceptions!
At the professional level of hockey or any other high-level of hockey the answer to this would be no (with one exception that will will get to in a second).
However, at an amateur or recreational level hockey is often divided into two halves often.
For example, a game is often slotted at the local ice rink for about one hour. Instead, of having three periods, which wastes extra time with an extra stoppage and teams changing sides, the game will only have two halves of 30 minutes each. Each team will switch once so each team will play from each side, and the game will have two halves.
The one example of two halves you will see at the NHL level is the NHL all-star game. The NHL all-star game is not like a regular NHL game – they play 3-on-3 instead of 5-on-5, the game is 40 minutes not 60, and they play two halves and do not have 3 periods.Embed from Getty Images
All of this is done to create a laid back atmosphere for the players where there can be a lot of scoring changes and a lot of goals. For better or worst, the NHL is doing this 100% to try to get as much scoring as possible, and not to showcase the game as it is regularly played.
Let’s get back to the flow of the game of a regular professional game with three periods.
After each period: Intermission and ice resurfacing.
Playing hockey in three periods makes perfect sense from an ice quality viewpoint. Instead of only having one opportunity to resurface the ice, having three periods allows the ice to be resurfaced twice: once between the 1st and 2nd period and the other time between the 2nd and 3rd period.
Once the ice is resurfaced by the zamboni machine, the quality of the ice significantly increases. The middle of the ice will also be resurfaced before a shootout takes place.Embed from Getty Images
The intermission length of 15 minutes does correspond with the ability of the ice to be cleaned and resurfaced. It does not take the whole 15 minutes as many NHL teams will have on ice entertainment between periods.
Even with the additional ice resurfacing that having three periods allows, the quality of the ice still deteriorates as the game goes on. This is mostly due to the effect of the temperature in the building being raised — having 15,000 – 20,000 people in the building creates some heat!
Ice does not do as well when the temperature rises 🙂
How long does it take to play a period in real time?
In real time a period will take approximately 40 minutes to play. This accounts for stoppages in play and tv timeouts so the network televising the game can show their commercials (there are two of these each period).
If each period takes about 40 minutes then the total game play will be 120 minutes with 30 minutes total for the intermissions gives a total of 150 minutes, or 2.5 hours. So from the time the puck is dropped to the final horn sounds it is 2.5 hours.
Sometimes the game will be a bit longer, but it is often not shorter than this.
Here is a real time flow of how the periods of hockey will flow at a professional game:
|7:00 pm||National Anthem|
|7:05||Puck Drop for Start of First Period|
|8:00||Puck Drop for Start of Second Period|
|8:55||Puck Drop for Start of Third Period|
|9:35||End of Game|
When I am watching a hockey game at home this is the general guideline that I go by. If I don’t want to watch the pre-game show or the intermissions I know that I roughly need to be in my chair at 7:05, 8:00 and 9:00 to make sure that I catch most of the action.
Of course, with streaming tv that you can pause and pick up when you want it makes it easier than ever. But I am a little old school and like to watch it live as much as possible.
Additional periods: Overtime
In a regular season game, if the game is tied at the end of regulation (end of the three periods), then an overtime period with 5 additional minutes will be added onto the game.
There is no intermission between the 3rd period and overtime and play starts within a few minutes from the end of regulation. If no team scores during this 5 additional minutes, then a game will be decided by a shootout.Embed from Getty Images
When the game goes to a shootout they will do a quick resurface of the middle of the ice. Each arena has two zambonis which will take a lap up and down the centre of the ice to smooth out the shooting areas for the players – this allows for the players to do more highly skilled moves on their shootout attempts and not simply be forced to shoot it because of poor ice conditions.
In the playoffs, if the game is tied at the end of regulation, then there will be a full intermission followed by another full period of twenty minutes.
This pattern will continue until somebody scores to end the game (sudden death). It has been common for multiple overtime periods to be played in the Stanley Cup Playoffs. To give you an idea, here is a list of the longest games in NHL Playoffs history:
Most Periods ever in an NHL game
|March 24, 1936||Detroit 1, Montreal Maroons 0||116 minutes |
|April 3, 1933||Toronto 1, Boston 0||104 minutes |
|May 4, 2000||Philadelphia 2, Pittsburgh 1||92 minutes |
|April 24, 2003||Anaheim 4, Dallas 3||80 minutes |
|April 24, 1996||Pittsburgh 3, Washington 2||79 minutes |
|April 11, 2007||Vancouver 5, Dallas 4||78 minutes |
|March 23, 1943||Toronto 3, Detroit 2||70 minutes |
|May 4, 2008||Dallas 2, San Jose 1||69 minutes |
|March 28, 1930||Montreal Canadiens 2, NY Rangers 1||68 minutes |
|April 18, 1987||NY Islanders 3, Washington 2||68 minutes |
Wow, those are long games!
Do they clean the ice during periods in recreational hockey?
It depends on the level, but usually not. The game will still be divided into three periods, but the end of the period will be simply a break for the team. A period in recreational hockey is usually played 20 minutes runtime, which means that during stoppages of play the clock will keep on running.
Therefore, the maximum actual time length of a game will be 60 minutes. This is usually fine given the nature of the players (they are not as hard on the ice as professionals).
The ice is then resurfaced at the end of the game, before the next game takes place.
In higher end leagues, it is common for the teams to play 20 minutes stop time per period – just like the pros. However, the ice will only be cleaned between the 2nd and 3rd period. These buildings are usually kept cooler than NHL rinks, so the ice stands up better during the course of a game.
