After day 20, when the husband died, and the son came back home, it is impossible to steer around the house.
My save is currently on day 23, nothing can be done around the house, the camera can not be moved. After the talk about the burial (the same as on day 22), the game automatically progresses into night, with the son as a playable character in the church. Nothing in the church is interactive, though, and there is no way to end day.
