It's time to start setting aside a lot more time for Game of Thrones on Sunday evenings.

Coming into the show's eighth and final season, fans were long promised that while Season 8's episodic count would be smaller than any other season, the run times for the series' closing installments would be much longer than prior years as well. While the first two episodes, "Winterfell" and "A Knight of the Seven Kingdoms," each clocked in at under an hour, now's when that so-called "movie length" we've heard so much about will really start to kick in.

Game of Thrones Season 8 Complete Coverage

Beginning with Sunday's big battle for Winterfell, the remaining four episodes of Game of Thrones will feature much lengthier run-times. In fact, nearly all of them will out-measure the show's previous record-holder, Season 7's finale, "The Dragon and the Wolf," which clocked in at 79 minutes and 43 seconds.

Here's a look at the run-times and air dates for all of Season 8's episodes:

Episode 1 ("Winterfell"): April 14, 54 minutes.
Episode 2 ("A Knight of the Seven Kingdoms"): April 21, 58 minutes.
Episode 3 (Title TBA): April 28, 1 hr. 22 minutes.
Episode 4 (Title TBA): May 5, 1 hr. 18 minutes.
Episode 5 (Title TBA): May 12, 1 hr. 20 minutes.
Episode 6 (Title TBA): May 19, 1 hr. 20 minutes.

In all, by the time Game of Thrones Season 8 is through, fans will have invested at least 432 minutes watching its final episodes — not counting the inevitable re-watches, of course. So far, we've seen just 112 of those minutes, which means that even though we're technically already a third of the way through Game of Thrones' last episodes, we've only watched about a quarter of the final season so far.

To quote Edd, "and now our watch begins."

Game of Thrones airs on Sundays at 9/8c on HBO.
