Help finding the sum of blank cells in a row that needs to never end

[mikeycantrell]

Basically I am trying to calculate how many blank cells are in a row of dates. The tricky part is that I need the formula to reflect added dates in the future so I do not have to edit it every time a new date is added.


I apologize in advance if this has been posted before or if have broken any forum rules. I am a noob here so any guidance or help would be greatly appreciated.

I'm assuming you mean the number of blanks between the first and last dates in the row. This is for row 4, change as necessary:

=COUNTBLANK(A4:INDEX(4:4,MATCH(9.99999999E+307,4:4)))
