I'm using Excel 2007 but I need this to work also on Excel 2003.

I want to set up a spreadsheet where I can automatically populate a set of
cells with incremental dates in the format MMM-YY.

When I use the MM-DD-YY format, I can do the following:

Cell 1: Enter starting date
Cell 2: = [Cell 1] + 1

With this, Cell 2 will increment the date from Cell 1. I can propagate this
way through the spreadsheet.

But, if I configure the cells for the date format of MMM-YY, it wont
increment. Can anyone tell me if I can use a simple formula to increment
dates in the format MMM-YY?
