compare table dates to measure date

[ajm]

how does one compare the dates in a table to a sliver date stored as a measure?

surprisingly good answer came from chatGPT. i am not wanting to be, but am, impressed.

with my slicer, which displayed dates from a date fact table, and my table (Forward Plan) which holds project date incl start and finish dates. Chat GPT came up with the basics and i copied to create the working measure.

Active Projects = 
VAR SelectedStartDate = MIN('ExtXLFileDates'[Date])
VAR SelectedEndDate = MAX('ExtXLFileDates'[Date])
RETURN
CALCULATE(
    DISTINCTCOUNT('ForwardPlan'[Description]),
    FILTER(
        'ForwardPlan',
        ('ForwardPlan'[Activity Start] <= SelectedEndDate && ('ForwardPlan'[Activity End] >= SelectedStartDate))
       ||('ForwardPlan'[Activity Start] >= SelectedEndDate && ('ForwardPlan'[Activity End] <= SelectedStartDate))
   ||('ForwardPlan'[Activity Start] < SelectedStartDate && 'ForwardPlan'[Activity End] <= SelectedEndDate && ('ForwardPlan'[Activity End] >= SelectedStartDate)) 
    ||('ForwardPlan'[Activity Start] > SelectedStartDate && 'ForwardPlan'[Activity Start] <= SelectedEndDate && ('ForwardPlan'[Activity End] >= SelectedEndDate)) 
    ))
