Well, Hellfire Club, it’s finally upon us. The very, very conclusion of Stranger Things, after nearly 10 years and five seasons of the Duffer Brothers’ hit Netflix series. We’ve pedaled our bikes through Scoops Ahoy sundaes and Spider Monster confrontations in the Starcourt Mall, through Billy’s Mind Flayer enlistment, all the way to jamming Metallica in the Upside Down and gazing into the Abyss.

The ultimate showdown with Vecna (Jamie Campbell Bower) approaches for our Hawkins heroes, with the penultimate episode gathering everyone at the Squawk radio station, poised to confront the mind-bending antagonist once and for all. But when, precisely, can you curl up with your Demogorgon plushie for the final showdown?

What time does the Stranger Things finale air?

The series finale of Stranger Things debuts Dec. 31 at 8 p.m. ET / 5 p.m. PT on Netflix. Naturally, you can also catch it in theaters (but by this point, you might be fortunate to secure a seat).
