What is the position of the moon in a month?

The orientation of the moon, that is, the orientation of the convex surface of the crescent.

Change of orientation within one month (lunar calendar):

In the first half of the month, the moon appeared in the middle of the night, and the sun had set in the west, so the convex surface of the crescent moon faced west.

In the second half of the month, the moon appears in the middle of the night and the sun is about to rise, so the convex surface of the crescent moon faces east.

Please note: both the moon phase map and the sky constellation map are "left east to west", which is opposite to the map direction!
