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 regulation hockey game consists of 3 periods that last 20 minutes each and 15 minute intermissions between periods each period with stoppages can go for about an average of 30 35 minutestherefore a hockey game will typically last about an hour and a half to two hoursn average high school football game lasts about an hour 1 2 2 hours they last longer if they go into overtime a regular game provided there is no overtime involved is 12 minutes per quarter 4 quarters with a 15 minute halftime but the final time depends greatly on how many times they stop the clock
