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.
Field Hockey: A regulation field hockey match at international standard consists of 2 halves of 35 minutes, with a halftime of up to 10 minutes. Timestops can add a lot to this-sometimes up to 20 minutes, but normally around 5 - for a total of around an hour and a half on average. For playoff games, after a 5-minute rest from full time, golden goal time is normally either 7.5 minutes or 15 minutes (2 x 7.5 with no break between).
