Hi Daniel,
The difference is your cell formatting before using Ctrl+;
The 14/May would have a cell format of dd/mmm
but the 14/5/2007 probably had a default cell format
of General the entry is a date so it used your
short regional date format the probably looks like d/m/yyyy
in your Control Panel, Dates

For more information on Date and Time see

I was able to use Ctrl+; with cells formatted dd/mmm in Excel 2003 and the
result was e.go. 14/May.

Now with similar cell formatting I get 14/5/2007 when I use the Ctrl+;

Does anyone know what is going on?
TIA
