On Monday night, Americans will get their first shot to see presidential hopefuls Donald Trump and Hillary Clinton face off in a debate. With the presidential debate scheduled to begin at 9 p.m. EDT, TV fans will have to deal with some changes to their favorite shows. 

Fortunately, shows such as “The Big Bang Theory,” “Kevin Can Wait” and “Gotham” will still air at their usual times, while other shows will be shorter than normal. Other fall shows such as “2 Broke Girls,” “Conviction” and “Timeless” have yet to air their season premieres, so they will not be affected. 

“Dancing with the Stars” on ABC at 8 p.m.

Dancing with the Stars” is usually a two-hour show on Mondays due to its results and performance segments, but tonight the show will only run for one hour from 8 p.m. to 9 p.m. The show will have a two-hour episode on Tuesday night.

“The Voice” on NBC at 8 p.m.

Just like “Dancing With The Stars,” NBC’s “The Voice” will cut its usual two-hour show down to a one-hour episode. But don’t worry, you’ll still be able to watch some of the blind auditions tonight. A two-hour episode will air on Tuesday night.

“Lucifer” on Fox at 8 p.m.

The only show not airing due to the debate will be Fox’s “Lucifer.” The show, which had its Season 2 premiere last week, will bump episode 2 to Oct. 3.

Tonight’s debate, which will take place at Hofstra University in Hempstead, New York, will air on all major cable and broadcast networks including ABC, CBS, NBC, CNN, MSNBC and Fox News. The debate will also be streamed on Facebook Live by ABC News, while CNN and Bloomberg Television will stream the debate on Twitter.
