Countif using dates

[Guest]

In column A I have dates in the following format;
01-Apr-05 right through until the end of March 2006
On a different sheet in my workbook I want to summarise the information by
counting the number of appointments between certain dates to get monthly
totals. I just don't know how to say that I want all dates between 01-Apr-05
until say 30-Apr-05p and so on. Is it possible to do this - the formula I
was trying with was;
=COUNT(IF('Master
Sheet'!$A$2:$A$10000=DATEVALUE("01/04/2005:30/04/2005"),1,0))
But this isn't working!

=SUMPRODUCT(--(A2:A1000>=DATE(2005,04,01)),--(A2:A1000<=DATE(2005,04,20))

If you are just looking for a month, you can use

=SUMPRODUCT(--(MONTH(A2:A1000)=4))

or if there can be multiple yers, then

=SUMPRODUCT(--(YEAR(A2:A1000)=2005),--(MONTH(A2:A1000)=4))

or

=SUMPRODUCT(--(TEXT(A2:A1000,"yyyymm")="200504")

Try...

=SUMPRODUCT(--('Master Sheet'!$A$2:$A$10000>=DATE(2005,4,1)),--('Master
Sheet'!$A$2:$A$10000<=DATE(2005,4,30)))

or

=SUMPRODUCT(--('Master Sheet'!$A$2:$A$10000-DAY('Master
Sheet'!$A$2:$A$10000)+1)=DATE(2005,4,1))

Hope this helps!

This also works:
=SUMPRODUCT(--(A2:A1000>="4/1/05"),--(A2:A1000<="4/20/05"))

 

[Bob Phillips]

Maybe, but we don't format dates like that in the UK, far better to use an
unambiguous way IMO, such as I showed or even

=SUMPRODUCT(--(A2:A1000>=--"2005-04-01")),--(A2:A1000<=--"2005-04-30"))

Bob - thanks for you prompt response - I'm still having problems, do you
think it's how I've formatted the cells with the dates in? I've got them so
that however the user inputs the date it comes up "01-Apr-05" format?

 

[Bob Phillips]

If they are dates, the format should not matter at all.

What problems are you experiencing? Do you get 0 or an answer which you
can't see the reason for?

Bob - spot on, I'm getting a '0' which I can't see the reason for!

Thanks - still puzzling over this as I copied and pasted the formula and am
now getting #ref

I'm sure this is me rather than you but I just can't understand it!

 

[Guest]

Thank you for all your help - have now found out the reason for my problems
when using all the suggested formulas....am VERY sorry to admit that I'd put
in the wrong date when trying it out so it was a simple case of user error on
my part. Thanks once again for all time taken from everyone!

 

[Domenic]

Make sure that the sheet name referenced in the formula matches exactly
the sheet name in your file.

 

[Bob Phillips]

Sounds like the dates are not real dates
