First, make your query putting in the fields you need to return.
Then, in query design, right-click and select parameters
Add a date/time field called "MyDate" or whatever you want to name it..
then set the Criteria field to be
[MyDate]
if you should need the query to return less than or greater than the date entered just change the criteria to
< [MyDate] or
> [MyDate]
That should take care of it.
