The NHL has posted the Conference Finals schedules.
The Penguins (#4 seed) will meet the Carolina Hurricanes (#6 seed), with home ice advantage, at the Mellon Arena beginning Monday, May 18. Game 2 is Thursday, May 21. Games 3 and 4 are at Carolina on Saturday, May 23 and Tuesday, May 26. Game 5 (if necessary) is Friday, May 29 at Mellon Arena; Game 6 (if necessary) is Sunday, May 31 at Carolina, and Game 7 (if necessary) is Tuesday, June 2 at Mellon Arena.
All games are at 7:30pm and will be nationally televised on Versus. Games 1-2 will be on TSN; games 3-7 will be on CBC.
(I’m pretty sure they’re trying to make sure the Stanley Cup Finals will conflict with the WWDC on purpose.)
