Stranger in Our House (1978)

Does anyone know if there is a way to tell when the second showing of Stranger in Our House was? This was the made for TV witch movie with Linda Blair and directed by Wes Craven. It premiered on October 31, 1978 (same night as Devil Dog: The Hound of Hell on a different network). I didn't see it then, but it was rerun some time later, I think probably in the summer or fall of '79. That's when I saw it. I'm trying to determine the exact date because it was the same day as soemthing else that happened to me that I'm including in a written work.
