How about one query where you specify the date range?

In the criteria "cell" under your Date fields enter the following.

Between DateSerial([Enter Year Number],[Enter Month Number],1) and
DateSerial([Enter Year Number],[Enter Month Number]+1,1-1)

Make sure you spell Enter Year Number and Enter Month Number the same in
both places.
When you run the query it will ask you for a Year number and a month number
and then will construct the dates using the DateSerial function.

Explanation of DateSerial
DateSerial needs a year number, month number and day number to create a
date.

To get the last day of the month we've used a bit of "magic".  The last day
of the month is also the zero day of the next month (Day 1 minus 1 = 0), so
we've added one to the month (+1) and then subtracted 1 (1-1 = 0) day.
