Can "COUNT" and/or "COUNTIF" look at dates?

[DA]

I am trying to count the number of issues opened during a
specific week. The formula is on one worksheet, the date
is on the "abc" sheet and the issues are on the "xyz"
sheet.

Can the Count function actually count "dates" or can it
just count numbers?

Here is my formula that is not working. I know the answer
should be 5 and it is returning 0.

=COUNTIF(xyz!D943,"<=abc!$R$1""and">=abc!$R$2)

Thanks!

DA,

Countif can only cope with one condition and you are using two conditions.
Use
=SUMPRODUCT(--(xyz!D943<=abc!$R$1)*(xyz!D943>=abc!$R$2))

By the way : As far as Excel is concerned Dates *are* just numbers. Excel
is counting day from 1-1-1900 (1) and further.

Hi
try (if R1 and R2 are dates as well as the range D943)
=SUMPRODUCT((xyz!D943<=abc!$R$1)*(xyz!D943>=abc!$R$2))

This worked...THANKS! I should have asked first and not
wasted 2 hours trying to figure it out myself!
