QUESTION: I am using Excel 2007.

I would like excel (using a formula)to count the number of entries I make per month when certain conditions are met. I have provided an example and spreadsheet layout below:

If A23 value is any date in Feb and B22 is greater than 1, then B23 should be 1. Now, the second entry I make for Feb in B24, regardless of the date, should be 2, and so on.

Second part:

Then, if A27 value is any date in Apr and B26 is greater than 1, then B27 should be 1. The second entry I make for Apr in B28, regardless of the date, should be 2 and so on. See below.

A B

22 31-Jan-16 33

23 3-Feb-16 1

24 5 Feb-16 2

25 6-Feb-16 3

26 10-Feb-16 4

27 4-Apr-16 1

28 7-Apr-16 2

29 12-Apr-16 3

I would like five months used in the formula: Feb, Apr, May, Jun and Sep.

Hopefully this makes sense. Thank you.

ANSWER: Larry,

Based on your example, I would say what you want is to start counting at 1 whenever the month in that row does not equal the month in the previous row otherwise, increment the value by 1.

So in B23 I would put

=if(month(A22)<>Month(A23),1,B22+1)

then select B23 and drag fill this formula down column B next to your data. Using what you show, I used this formula in B23 and drag filled it down and it reproduced what you show for column B starting with row B23.

QUESTION: Hello Tom, thank you for such a fast response. I am just getting back to you because I had to leave yesterday afternoon. Anyway, if possible, I would like to provide the following additional information.

1) If possible, I would like the formula you sent me to only apply if the months in column A are specifically Feb, Apr, May, Jun or Sep. If the months in column A are Oct, Nov, Dec or Jan, I do not want to start back at one. I would like the count to continue from the previous month. For example, if A23 is the month of Oct, then I want B23 to equal B22+1, then B24 will equal B23+1 and so on until Feb hits again, which at that time it will start back at one. See below example.

2) Also, when I drag down a formula, is it possible for the result in column B to only appear when there is an entry in column A. For example, since nothing has been keyed in A27, then nothing should appear in B27. Please see below.

A B

22 28-Sep-16 45

23 2-Oct-16 46

24 4-Oct-16 47

25 5-Oct-16 48

26 7-Oct-16 49

27

28

29

Thank you again for being so quick.

Larry

Larry,

If you want to send me a copy of your workbook with all your dates I will take a look and see if I can come up with a formula for you. Otherwise, I just have to guess at what I would have to take into consideration.

you can send it to twogilvy@msn.com
