How Many Hours to Watch It's Always Sunny in Philadelphia? Here's the Full Breakdown

But for anyone planning a full binge, the time commitment is massive.

Total runtime:

• With commercials: 3 days, 16 hours, 30 minutes
• Without commercials: 2 days, 14 hours, 38 minutes

That's every single episode from Season 1's 2005 debut to the end of Season 17 in August 2025 — all before the already-confirmed Season 18 arrives.

How long will Sunny run?

Fans are split on the show's eventual endpoint. Many want it to hit at least 20 seasons.

"You gotta do 20," one fan wrote. "Then afterwards you can do whatever… hopefully continue the show beyond 20 seasons."

Rob McElhenney, who plays Mac and co-created the series alongside Charlie Day and Glenn Howerton, has said it will keep going "as long as people still want to watch it." But the cast's other commitments — from acting roles to McElhenney's co-ownership of Wrexham AFC with Ryan Reynolds — add uncertainty.

Danny DeVito, who joined in Season 2 and is now 80, is often cited as a key factor in the show's longevity. Some fans believe it should end with him, while others propose creative send-offs.

"Whenever Danny retires or moves on they should stop," one comment read. "I saw a great fan idea… if Danny were to die in real life, they would have secretly filmed the final episode already with Danny where every other character dies and Frank is the sole survivor."

DeVito himself has said he'll keep acting until he dies, a fact that reassures some and alarms others. "I hope they keep it going till Danny passes, and then call it a wrap in his honor," another fan wrote, adding that the loss would hit "just as hard if not worse than when Robin Williams passed away."

The quality debate

The show's creative consistency is another flashpoint. One commenter argued, "Everyone just needs to look at the state The Simpsons are in. Shows need to end." That sparked heated pushback:

"One of the most epic and brilliant episodes was 'Dennis Takes a Mental Day' — the very last episode of last season. So 'quality over time' debunked, dummy!"

Others countered that money drives the decision more than artistic integrity. "They still have a dedicated fan base who enjoy the show and they're creating generational wealth for their families. They'd be dumb as hell to give that up just because a few randos say they should," one user said. Another shot back,

"If you're doing it just for the money it will show. And in my opinion, it already has."

The fandom remains fiercely loyal, with some defending the series as still "miles better than other comedies on right now" and praising its ability to fund cast members' more experimental projects. But even die-hards admit that if the fun stops for the cast, Sunny will end — whether that's at Season 18, 20, or far beyond.

For now, anyone looking to watch it all before the next season better set aside at least two and a half days — and maybe some rum ham.
