FXX announces a 13-Day Simpsons marathon that will include all 600 episodes in chronological order.

In order to celebrate the feat of reaching 600 episodes, FXX is going to hold a Simpsons marathon starting 12:00 PM on Thursday, November 24.  The marathon will run for 300 hours (13 days) and end on Wednesday, December 6 at midnight.  This will mark the longest-running marathon in television history, beating out FXX’s previous 12-day, 552-episode Simpsons marathon in 2014.

Here’s what FX Networks President and COO Chuck Saftler had to say about the marathon courtesy of Coming Soon.

“The first ‘Every. Simpsons. Ever.’ Marathon was truly so special and landmark in its cultural relevance and impact.  The unprecedented feat of reaching 600 episodes deserves something of that caliber to mark it and celebrate it. Doing this is an act of true fandom, honoring Jim Brooks, Matt Groening, Al Jean, all the writers, artists, directors, people behind the scenes and the ridiculously talented voice actors who have brought this series to life and kept it at the pinnacle of artistic excellence these past 27+ seasons.”
