The simplest solution to defeating this annoying date feature is
1)
Save your workbook defaults in the workbook template file “Book1.xtlm” in the XLSTART folder
a.
Search for the
XLSTART folder in explorer; every computer is different
b.
Paste a shortcut to the XLSTART folder on your desktop (you will thank me)
c.
You will probably edit all the defaults several times;
number format, gridlines on, horizontal display etc..; so the desktop shortcut helps
2)
Since you cannot create a worksheet template file in 2010 (you can in 2003 & 2007); then record
a macro to insert sheets with your defaults
a.
Give it a useful name like “InsertSheet_MyDefaults1”;
b.
so record macro, give it name, F11, select all, select your formats (number, etc…); stop recording
3)
Now when you want to enter dates instead of numbers you should block reformat the cells and format them to the date format you like best
a.
You could record a macro for that as well
4)
Store all your macros in “personnel.xlsm” and save in XLSTART
a.
If all your macros are in this folder in XLSTART; then they are available to every sheet when you enter excel; once again the desktop shortcut helps
Good luck
