Upper Allen Township and Keystone Marker Trust, a non-profit organization, have collaborated to restore the historic Shepherdstown Keystone Marker located on the Gettysburg Pike.
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.
Our average length of game in 2003-04 was two hours and 19 minutes. So we do not expect games to run longer. The following page has other information about NHL games as well. http://www.nhl.com/nhlhq/cba/relaunch_faqs072205.html. A game that is tied at the end of regulation play will be longer. There is no intermission at the end of regulation. There is a 5-minute maximum (on the play clock) overtime period.
