1) “25 Days of Christmas” begins, Freeform. Ever since 1996, Freeform has turned December into a Christmas marathon. That seemed big at the time … and almost modest now. Still, there’s a lot to see here. “Eloise at Christmas” (11 a.m.) has lovely visuals and Julie Andrews (shown here). “The Star” (1 p.m.), is a cartoon about animals at the nativity. Then Jim Carrey is Scrooge and the Grinch (3 and 5 p.m.), followed at 7 by “Home Alone” films.
2) More Christmas. Hallmark has been going global lately; “My Norwegian Holiday” (8 p.m.) has a woman treveling to trace the background of a troll figure. There’s more, on streaming: Apple TV+ (the home of “A Charlie Brown Christmas”) adds Christmas specials from “The Snoopy Show” and “Frog and Toad.” Amazon Prime has “Candy Cane Lane,” an action comedy with Eddie Murphy desperate to win a home-decoration contest.
3) Pac-12 championship game, 8 p.m.. ET, ABC. Here’s the football finale for what was known as the “conference of champions,” the leader in overall national titles in team sports. Ten schools are leaving Aug. 2 for three other conferences; the two that remain are suing for conference assets. For now, Washington and Oregon (ranked No. 4 and 6 in the nation) collide; they’ll be in the Big Ten next year.
4) More streaming. “The Shepherd” (Disney+) has John Travolta as a mysterious figure, guiding a pilot home on Christmas Eve. “May December” (Netflix) is a fictional version of a true story: A teacher, 34, was convicted of having sex with her student, 12; they later married. In this version, Julianne Moore plays a woman now married to her young lover; Natalie Portman plays a writer, trying to learn more.
5) ALSO: There’s another conference-championship game tonight, with Liberty (ranked No. 25) hosting New Mexico State, at 7 p.m. ET on the CBS Sports Network. And at 9 p.m., CW’s “FBoy Island” is a week from its finale. The guys in “limbro” are let out to “mansplain” themselves.
