For the 2017–18 season the NHL regular season formula was adjusted to account for the addition of the Vegas Golden Knights. Each team plays either four or five games against the other teams in its division (a total of 26 or 29 games in the Western Conference, 28 games in the Eastern Conference) as well as playing all non-divisional teams in their own conference thrice (21 or 24 games in the west, 24 games in the east). The remaining games of the season are inter-conference play (32 in the west, 30 in the east), allowing every team in the league to play every other team twice. The schedule is structured so that every NHL team plays in every arena at least once per season.
