countif function using dates

[Guest]

I want to calculate the number of entries in a column that are later than one
date and earlier than another.
This is what I thought would work, but doesn't:
=COUNTIF(M3:M158,">30/09/2007"&"<01/11/2007")

Try it this way:

=COUNTIF(M3:M158,">30/09/2007")- COUNTIF(M3:M158,">=01/11/2007")

Hope this helps.

=SUMPRODUCT(--(MONTH(M3:M158)=10))

Will not work if the month is January and if there happens to be some blank
cells
included.

You're absolutely correct. For the month of January must have year included

=SUMPRODUCT(--(MONTH(M3:M158)=1),--(YEAR(M3:M158)=2007)

 

[Guest]

=SUM(COUNTIF(M3:M158,{">2007/9/30",">2007/10/31"})*{1,-1})

 

[Guest]

=SUM(COUNTIF(M3:M158,{">30/09/2007",">31/10/2007"})*{1,-1})
Revised for the date format

And, for the month of January :

=SUMPRODUCT(--(TEXT(M3:M45,"m/yyy")="1/2007"))

It worked! Thanks very much Pete.

Try it this way:

=COUNTIF(M3:M158,">30/09/2007")- COUNTIF(M3:M158,">=01/11/2007")

Hope this helps.
