Hi All,

Is there an easy way of counting the number of instances certain dates appear in a range?

I am using this formula:
{=(COUNTIF(LABS!$A$5:$A$21,">=1/5/2006")-COUNTIF(LABS!$A$5:$A$21,">=1/6/2006"))}
to count the number of times any date in May 2006 appears in the range.

It seems overly complicated!

Any suggestions?
 

Excel Facts

Difference between two dates
Secret function! Use =DATEDIF(A2,B2,"Y")&" years"&=DATEDIF(A2,B2,"YM")&" months"&=DATEDIF(A2,B2,"MD")&" days"

Here is another suggestion, but it is not much (if any) simpler than your solution:
=SUMPRODUCT(--(MONTH(LABS!$A$5:$A$21)=5),--(YEAR(LABS!$A$5:$A$21)=2006))

Not sure what you mean by overly complicated, but entered with just Enter

=SUMPRODUCT(($A$5:$A$21-DAY($A$5:$A$21)+1=$B1)+0)

Where B1 houses the first day of the month you're trying to count.
