If you don't need formulas and you are XL2002 or better then select the 2
date. Drag them as usual. When complete select the Fill options at the bottom
right of the filled cells. Choose months... You can get the same thing
dragging with the right mouse button and choosing months.

I need to create column headers that show a date progression through several

everything in my fill series options, but nothing is working (I even tried
".5 months")
Is there a simple answer to this?

Thanks for your help.
