The dark side of the moon NEVER faces the earth. It's in a state that they call "Tidal Lock". You and I can never see the dark side of the moon unless it's a picture taken from beyond or in orbit of the moon. Sometimes you can see the moon during the daylight if the conditions are right, but usually the sunlight washes it out from view.
If the side of the moon that is dark was always facing away from us we would never see anything but a full moon. The moon is tidally locked with the earth, so one side is always facing away from us, but the same side of the moon is not always darkened.
When the moon is passing in front of the sun the dark side is facing us. And it is daytime. That is why you don't see it.
