Stop what you're doing and turn on PBS! There's a Downton Abbey marathon airing today (Sunday, February 17) in advance of the finale, which will air from 9 to 11 p.m. on PBS.

The marathon starts at 1 p.m. and includes all the episodes of Season 3, including what the Brits called the "Christmas special" since it aired at Christmas for them. We get it in February so we're basically just calling it the finale. That's the last new episode of Downton Abbey we'll get until the Season 4 premiere. Season 4 is filming right now, but we're probably not going to get to see it until January 2014. Yes, it's frustrating!

But you can read some teaser spoilers now, if you want some scoop on what will happen. The scoop will be better after Season 4 airs in the U.K. Right now it's just general intel.
