Hi Chuck,
>I think it's just a display issue in Excel. If you look the cells the dates are filled in and if you delete the "overflow" values in Excel and pagedown then up again, to refresh the screen, you will see the dates are display correctly.
Yes, it seems that's what's happening. If you select cel, say, D14 of the spredsheet and enter =C14 Excel displays cel C14's value correctly.
