It's the Easter Beagle, Charlie Brown premieres on AppleTV+ on March 26, 2021

It's the Easter Beagle, Charlie Brown will premiere on the Apple TV+ subscription streaming service on Friday, March 26, 2021.

No over-the-air television broadcast of Easter Beagle is scheduled for 2021, and there's no free viewing period like there was for the Thanksgiving and Christmas specials... it's only available to Apple TV+ subscribers.  (Although you can always watch or get it on DVD, too.)
