Return to previous month based on cell value

[herukuncahyono]

hi

I want to make the function to return previous month base on other cell value.
e.g. if A1= jan , B1= dec .

There's a formula based on current date ;

=TEXT(DATE(2004,IF(MONTH(TODAY())-1>0,MONTH(TODAY())-1,12),1),"MMMM")

I expect every suggestion

What does this mean. There can be hundreds of suggestions... how can you "expect" every suggestion. We are here to help not here to meet your expectations.

To best describe or illustrate your problem you would be better off attaching a dummy workbook, the workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook.

If needed supply a before and after sheet in the workbook so the person helping you can see what you are trying to achieve.

Doing this will ensure you get the result you need!

I get the formula above from google( just copy paste), I tried to worksheet and was used only for current date (today).
I want to modified but Which parts should be changed.

Try either:

=EDATE(A1,-1) needs to have Analysis Toolpak Installed through Tools|Addins menu.

or

=DATE(YEAR(A1),MONTH(A1)-1,DAY(A1))

Format cell as custom: MMM

hi NBVC,

The second formula is precise and simple.

Sorry for using the wrong word and thank you for your help
