Each NHL game features 60 minutes of playing time, broken down into three 20-minute periods. The league also mandates a 17-minute intermission after the first and second periods to flood and ice and provide the players with a rest period.
a professional hockey game is comprised of three 20 minute portions called periods there are short breaks in between periods for the ice to be resurfaced and the players to get a little breather the duration of a game from start to finish varies but usually lasts somewhere between 2 1 2 and 3 hourso 2 3 hours but most often an nhl game is 2 5 hours in previous years games took a lot longer because players used to take their sweet time to get back to the face off circle
