What day does this conversation take place?

Man: Were you home last night? Did you watch TV?
Woman: No, I was out having dinner with some friends. Did I miss a good program?
Man: Yes, there’s a great comedy on every Wednesday at six. You know, that one that everyone is always talking about. It’s really funny.
Woman: I know the one you mean, but I’ve never had the chance to see it. Six o’clock is a bit early for me to watch TV. I usually don’t get home until seven.
