BBC America has announced the premiere dates for both "Doctor Who" and its spinoff, "Class."

"Doctor Who" will return for its latest season on BBC America at 9 p.m. ET on April 15, as reported Monday by Entertainment Weekly. Immediately following the season premiere of "Doctor Who" will be the pilot episode of "Class," an episode that includes the Twelfth Doctor making a guest appearance.

This news comes only hours after actor Peter Capaldi, who currently stars as the Twelfth Doctor on "Doctor Who," will be departing the series following this year's Christmas special. Capaldi, like actors Matt Smith and David Tennant before him, has starred in three series of "Doctor Who." When asked back in December whether he'd continue on as the Doctor, Capaldi revealed he wasn't entirely sure, and that he was trying to avoid making that decision. That has since clearly changed.

Fans of the series will also see plenty of changes behind the camera when the series returns with its Thirteenth -- and final? -- Doctor, as current showrunner Steven Moffat will also say goodbye to the series. As previously reported, Moffat will be replaced by “Broadchurch” executive producer Chris Chibnall in 2018.

Joining Capaldi for his final turn as the Doctor is newcomer Pearl Mackie, who will play his new companion Bill. Returning this season are Matt Lucas (Nardole) and Michelle Gomez (Missy).

"Class" is the second "Doctor Who" spinoff, following "Torchwood," that starred John Barrowman as Captain Jack Harkness and ran from 2006 to 2011, and "The Sarah Jane Adventures," which ran from 2007 to 2011. This latest spinoff is the work of author Patrick Ness ("A Monster Calls"), and is set at Coal Hill School, featuring the students trying to save the world from "extraterrestrial baddies." The show stars Greg Austin, Fady Elsayed, Sophie Hopkins, Vivian Oparah, and Katherine Kelly, and starts its run in the UK back in October.
