Calculating total unique days with multiple entries and date range overlap

[Bearcat22]

I am having trouble with a utilization report I am trying to build in calculating the total number of unique days an Object was in service. My table contains a start and an end date for each ObjectCode but an object can have two entries in a single day, or have an overlap in the date range for example :

7/27 has two entries and therefore would give me an extra day if I were to sum this column by the selected month. How can I find a count for only the unique days in the selected month?

@Bearcat22 An apporach would be to expand out your dates, so instead of the start and end of the range, show by each day in that range, called say InServiceDate. Now you can count rows per InServiceDate. Optionally you could add a Date table to your model. Join The Date table to the InServiceDate.
