I am going to interpret your question that you have records with a single date on them. Then you want to let the user run a report where they can specify a range of dates.
So just create a regular Table report, which is just a list of records and in the filter section select where the date is or after
And then it should give you a drop-down choice of ask the user
Then put that filter on the report, a second time as a filter and this time where the date is on or before and again choose ask the user.
The effect should be that when you run the report, it will ask you those two questions and you should be able to answer them and get results.
