"on the far side of the Moon, which is not visible from Earth"

Once a month for the calender new Moon, are we not seeing the dark side of the Moon?

The Moon's rotation is 27 days.

Luna is tidally locked to Earth. We always see (mostly) the same side of it. The far side of the Moon isn’t always dark, any more than the near side is.
