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.
During playoff games, the overtime period lasts for 20 minutes or until a goal is scored. Field hockey varies in length and there are two periods with an intermission in between. Each period lasts for 35 minutes and the interval in between is 5 minutes long. If the game ends in a tie, two 10-minute periods take place to determine the winner. The team with the highest score at the end of the overtime periods wins the game. On occasion, sudden-death overtime is held in field hockey.
