Count of Items within a specified date range

[JLambs20]

Hello,

Recently I got help from some great community members with a measure that shows all data points inside of a selected date range (but not using a start or end date in the filter visual).  That was successful but I'd like to take it one step further.  I would like to be able to count the items that show up within a specified range (whether that be by year, quarter, month, or day).  For example, I have selected Q3 in my filter and this is returned in my Gantt chart:

 

As we can see, there are 5 items that "exist" in Q3 (even though part of the tasks exist outside of the date range) so I would like to have a matrix that could show that number.  Here is the code that was used in my previous post:

Is Task Visible=

VAR startDate =

     SELECTEDVALUE ( 'SD Time Off'[Time Off Start Date] )

VAR endDate =

     SELECTEDVALUE ( 'SD Time Off'[Time Off End Date] )

RETURN

IF (

       startDate <= MAX ( 'All Dates'[fulldate] )

             && (

                      ISBLANK ( endDate )

                             || endDate >= MIN ( 'All Dates'[fulldate] )

                ),

       1,

       0

   )

This formula was used on the gantt in this way: 

I then use a date field from a date table in my filter to select the desired dates. 

That all being said, how do I write a measure to be able to count the items? Any assistance would be greatly appreciated!

@JLambs20 , Try new measure like

countx(Filter('SD Time Off', 'SD Time Off'[Time Off Start Date] <= MAX ( 'All Dates'[fulldate] ) && (
ISBLANK ( 'SD Time Off'[Time Off End Date] )
|| 'SD Time Off'[Time Off End Date] >= MIN ( 'All Dates'[fulldate] ))
), 'SD Time Off'[Time Off Start Date])
