If Venus is between the earth and the sun it should not be possible to view venus at certain hours during the night because the observer's view would be facing away from Venus since the observer's view would  be facing away from the sun once one is deep enough into the night.  Now if the distance between Venus and the sun is less than the distance between the earth and the sun at certain times of night it should not be possible to view venus in certain parts of the sky no matter where Venus is positioned within that distance from the sun or less.

Some astronomy guidebooks will tell you that because Venus is a so-called "inferior" planet — a world  that is closer to the sun than Earth — that you can never see it in the middle of the night. But this week, for many locations, Venus will be visible at the witching hour and for some localities well beyond the stroke of midnight!
