1) “Ghosts,” 9 p.m., CBS. It’s been a long time since anyone held a dinner party in this big old house. When the new owners (shown here, foreground) invite the nosy neighbors, the ghosts want to join in; they soon create problems … and a solution. That’s in a fairly good, all-rerun night for the CBS comedies, starting with “Young Sheldon” being a lab assistant.
2) “Station 19,” 8 p.m., ABC. This holiday episode has some quick crises and a chance for a Christmas miracle. But overriding everything is the recent death of Dean Miller, a popular firefighter.

4) “Women of Worth,” 8 p.m., NBC. Here are non-celebrities making a difference: A med student works on solutions to the rising bias against Asian-Americans … a public relations person brings attention to the underreporting of missing Blacks … a mom honors her late son by bringing attention to depression among youths. Those and seven more are interviewed in Paris and their home towns.
5) “Dogs of the Year,” 8 p.m., CW. We meet Levi, the official dog of Pennsylvania … and Ricochet the surfing pup … and Sampson, the only dog with access to a University of Illinois chemistry lab. There are others, including Mercy (scent-detection), Clover (a hero) and more
