Excel/Formula to add 1 to the number every month


We have a column that tracks number of months in care for each client.  I would like to have Excel add one (+1) on the first day of each month.

Currently the cell contains a number, not a formula.

Also, we use MSExcel 2003.


For that to occur automatically via formula would require a reference cell to store the "starting date".  So, if in D2 you listed the starting date as 2/1/2012 (Feb 1, 2012), then in E2 this formula would tell you how many months have passed since then:

    =DATEDIF(D2, TODAY(), "m")

You have to decide if you want the result to be INCLUSIVE of February.  So on Feb 2, you would still want the formula to result in 1, then the formula would be:

    =DATEDIF(D2, TODAY(), "m") + 1
