Your question is unclear. Do you mean a date range [e.g., 5th to 9th] or a list of dates [e.g., 5th, 11th, 14th, 15th, ...]?
It looks like you still have dates and times strored as strings in your data table. Again, this is going to slow down performance and what you are trying to do in this question will make it worse. You really need to fix this as suggested in the answers to your previous questions on this query.
