Date "yyyymm"
 

I have a worksheet were the dates are displayed as 200901 (yyyymm --- no
slash) in column A.
I need to add a formula to cells in colum C that will only substract any
given number of months from this date, such as 200901 minus 13 months will
equal 200811. Now, on the same boat, I would like to show the new date
displayed as 11/01/2008.

Thank you

I guess I don't understand your math.

I would interpret 200901 to be 2009 Jan and, since the day is not specified, to
be the first of Jan. In other words, 200901 -- Jan 1st, 2009

How do you subtract 13 months from that and get Nov 1st, 2008?

If I subtract 13 months, I would think the correct answer should be Dec 1st,
2007.

If my assumptions are incorrect, please clarify.

If your examples are incorrect, then try:

A1: 200901
B1: -13 (months to add/subtract)
C1: =DATE(LEFT(A1,4),RIGHT(A1,2)+B1,1)

Format C1 as mm/dd/yyyy
--ron

Date "yyyymm"
 

First off, 13 months subtracted from January 2009 is not November 2008 (nor
would 3 months be if the 13 were a typo). Staying with you 13 month number,
here is the formula...

=DATE(LEFT(A1,4),RIGHT(A1)-13,1)

You can replace the 13 with whatever you want (or use a cell reference in
its place to make the value changeable). As for how you want to display the
resulting date, just format the cell as desired.

If 200901 was in cell A1, and 13 in B1, this formula:

=DATE(LEFT(A1,4)-INT(B1/12),RIGHT(A1,2)-B1+12*INT(B1/12),1)

should do what you want. I make it 01/12/07 (or 12/01/07 for America...) not
november 08 though.

=DATE(YEAR(A2),MONTH(A2)-13,DAY(A2))
and format the result cell to meet your needs! But 200901 - 13 months
results in 200712 and not 200811. If you want 200711 then
=DATE(YEAR(A2),MONTH(A2)-14,DAY(A2))

Given the flakiness of the web interface I would come back periodically to
look.

See my thread "not receiving notifying e-mails"! I followed Ms-Exl-
