Another option is to use a dedicated TV schedule website or app. There are several out there that aggregate TV schedules from various sources. Just search for 'A Christmas Story' on these platforms, and they should show you the relevant airing times based on your location.
You can usually check your local TV guide, either the printed version that comes with your newspaper or the digital guide on your cable or satellite TV provider's interface.
Some streaming platforms might also have information about when 'A Christmas Story' is scheduled to air. For example, if it's available on a service like Hulu or Amazon Prime Video, they may list any upcoming showtimes. Additionally, the official website of the network that has the rights to air the movie might have a schedule section specifically for it.
