It is the Will of God that the Moon should keep one face pointed to
the Earth.
The Will of God, see above.
In that case, it would take about 29 1/2 days for the Moon to rotate
once on its axis.
Or, more precisely, 29 days, 12 hours, 44 minutes, and 3 seconds. This
is about 708.734 hours.

so if you wait for the twilight to darken a little bit you may see it

in the year.

You can have old fashioned looking fixtures that are still full cutoff.
There is no-one to see the light that goes skywards so it may as well be
