The Late Show with Stephen Colbert is taking its spring break, as no new episodes of the late night talk show are going to air for the week of April 21-25. Reruns of The Late Show will instead air all week at the show's usual time, 11:35 pm ET/PT on CBS.
As for why The Late Show is not airing new episodes this week, Stephen Colbert offered no specific reasoning on his most recent show on April 16, nor has Paramount/CBS, so this just seems like it’s a scheduled break for the show, ones they take from time to time throughout the year. The last week-long break for The Late Show came back in March, during the first week of the March Madness college basketball tournament where games aired late into the night.
