Excel/Counting unique dates between 2 dates


Hi Tom,
I am trying to determine the unique days that fall between two dates in a list of total dates.

I have a list of dates represented by named range 'DateCount'.
I have a starting date for the formula in C39.
I have an ending date for the formula in E39.

I am trying to determine the unique days in this list of dates, that also fall between the two dates in C39 and E39.

I tried using this array formula but something wasn't working out.
Do you see any errors in the formula or do you perhaps have a better way of solving the problem?


Thanks for the help,


same suggestion I gave to your previous question.  I have modified your formula to include that concept and it worked fine for me.
