When you precompute info about the moon (with one app or so) often is mentioned the phase and age of the moon.
For instance on 26-1-2020 at 51°N 04°E a program gives Phase=0,3 Age=2.
I looked outside on the given time, direction and height and, no moon visible. (No clouds off course)
So I wondered from which Phase/Age is the moon visible for the naked eye?
