Result Based on Date Criteria

[Guest]

Hi,

This is my first post but I want to thank everyone who has posted before me
as I have been able to learn so much from previous questions.

I have a column in a spreadsheet (H7:H129) that covers a range of dates -
and these dates can go across more than one year. I have learnt how to count
the number of times a certain month appears but now I want to count the
months dependent on the year, eg count how many entries there are for July
2006, September 2006, November 2006 etc.

This spreadsheet will be used for years into the future so I want it to
automatically read the year from the worksheet. There is already a cell in
the worksheet where the date is manually inserted at the start of the month.
It displays as mmm-yy.

Any assistance will be greatly appreciated.

Thanks in advance.

Hi,

This is a little verbose but it will give you the month and year of a date...
you can then do your analysis on this column.

=LOOKUP(MONTH(A15),{1,2,3,4,5,6,7,8,9,10,11,12},{"January","February","March",
"April","May","June","July","August","September","October","November",
"December"})&" "&YEAR(A15)

If you don't care about having January then simple =month(A15)&" "&YEAR(A15)
will work.

One way to count the January 2006 dates:

=SUMPRODUCT(--(TEXT(H7:H129,"yyyymm")="200601"))

You may want to learn more about pivottables. You can group by month and year
and get a count for all your data pretty quickly.

ps.

Adjust the ranges to match--but you can't use whole columns.

=sumproduct() likes to work with numbers. The -- stuff changes trues and falses
to 1's and 0's.

Bob Phillips explains =sumproduct() in much more detail here:

You could use a pivot table to accomplish this. One advantage is that pivot
tables have built functionality when grouping date fields that will group
records by month and year.

Fantastic. Thanks Dave that worked as a short term measure - I don't want to
have to keep changing the year date for the results.
Will now look and learn about pivot tables as has been suggested.
