A naked-eye observer who tracks the rise and set position of the moon on the horizon will see that for half a "month" the position moves farther south each day and then for another half "month" moves farther north each day. How long is this "month"?

This seems copy/pasted. Please forgive me if it's not, but is this a homework question you joined to ask?
It's OK if it is, but it's important for us to know.

When people fight to keep something as basic to human survival as healthcare a privilege, but insist the right to bear arms inviolate, we cease to move forward as a society. -- zapatos

If you had gone to Wikipedia.org and typed "lunar month" you would have gotten your answer. Amazing how much Wiki knows.
Wiki says a lunar month is approx. 29.53 days.
Try Wiki first. If that doesn't work, ask here.

When in doubt, Wiki it out.

It is not a homework question. I am constructing a Ppt on archeoastronomy and I am trying to find the number of days for the moon to go from its most northerly rising or setting point on the horizon to its most southern point, and back again. I am aware of the longer 18.6 year cycle but I have not able to find the length of this shorter cycle. There are several versions of a lunar "month" and I am not sure what this one is.
