Dear Rob

Another way using COUNTIF(). With dates in Column C in date format..

=COUNTIF(C:C,""&DATE(2009,4,21))-COUNTIF(C:C,""&DATE(2009,5,20))

If this post helps click Yes

I want to count the number of cells that have a date entered, in a period of
30 days, in a column with over a thousand cells. Some of the cells are blank
while others have random dates entered spanning a period of many years.

(I.e. How many cells, in the above mentioned column, have a date that falls
in the period between 21-Apr-2009 until 20-May-2009 ?)
