Start your countdown clocks for Halloween [1] 2017! The Super Bowl teaser ad [2] for Stranger Things [3] season two revealed that's when highly-anticipated new episodes will return, but the most recent teaser (the third, if you're counting!) clarified that the show will actually premiere on Oct. 27.

While you wait, read up on what else we know about season two [4], like the new cast members [5] and when it will be set [6].
