The CW has announced its midseason schedule, setting a premiere date of Thursday, January 21 for its post-apocalyptic drama “The 100” and new series “Legends of Tomorrow.”

As a result, the network’s current Thursday lineup of “The Vampire Diaries” and “The Originals” will move to Fridays and will continue with new episodes the following week, on Friday, Jan. 29.

The move to Fridays comes after “Reign” wraps up its winter finale on Jan. 22. The rest of the season of the Adelaide Kane-led drama will return later, with a premiere date to be announced.
