COUNTIF between dates and if value = "y"
I have been using the COUNTIF function to count the occurences of dates that
fall between a particular set of dates. Is there a way to count these dates, only if a cell on the same row as the counted date equals 'Y" This is the formula that I have been using to count occurences between Dec.31-06 and Dec.31-07. =COUNTIF(A1:A5,"<=12/31/07")-COUNTIF(A1:A5,"<=12/31/06") Can I add to this in order to count the cells that also contain a "y" on the same row? Column A are the dates, Column B are the Y or N values. A B 1 Sept-08-06 Y 2 Oct-24-05 N 3 Jul-21-07 N 4 Aug-10-07 Y 5 Jan-01-05 Y The date COUNTIF formula shown above would result in 2. (A3 and A4) The result I am looking for (with the "y") should be 1. (A4 only) Any ideas ? Thx. |

Try this:
=SUMPRODUCT(--(A1:A5=DATE(2006,12,31)),--(A1:A5<=DATE(2007,12,31)),--(B1:B5="Y")) Better to use cells to hold the criteria.

I think that 12/31/06 should be excluded given the countif formula the OP
posted, that means it can be done using YEAR -- Regards, Peo Sjoblom "T. Valko" wrote in message ...

Yeah, when I see a posted formula like:
=COUNTIF(A1:A5,"<=12/31/07")-COUNTIF(A1:A5,"<=12/31/06") I always assume (for better or worse!!!) they meant = and <=.

This works quite nicely. Thanks very much.
However, I will need to swap out my COUNTIF formula to the SUMPRODUCT formula shown below in order to keep my values consistant. =SUMPRODUCT(--(A1:A5=DATE(2006,12,31)),--(A1:A5<=DATE(2007,12,31))) All I did was remove the "Y" array.

Hello,
Just some clarification... The formula below subtracts all of the dates that are <= 12/31/06 from all dates that are <= 12/31/07. This will give me a count of all the dates from 01/01/07 to 12/31/07. I wasn't aware that a conditional like " <= and = " could be used in a COUNTIF. If it can be....great. "T.

What's wrong with using the YEAR on one array instead of = and <= on 2
arrays? -- Regards, Peo Sjoblom "JohnLVand" wrote in message ... Hello, Just some clarification...

I misinterpreted your intentions. Since all you want to do is count entries
for the year 2007 Peo's suggestion is the best solution. I understand the logic of subtracting <= and <= but it seems more intuitive (to me) to use = and <= -- Biff Microsoft Excel MVP "JohnLVand" wrote in message ... This works quite nicely.
