Anyway the solution was obviously to include the month name. My first reaction was to change FLDTYPES.xml, then to create a custom field type, and finally it soon became obvious a calculated field should do the trick.

So I searched a minute for a formula to render the date with the month name in the middle… I didn’t find any so I created it.

It is a piece of cake to do it in VB and C#, but what does a calculated field provide? As it turns out quite a lot. Everybody knows your classic [Today], LTrim, etc… but what I didn’t know it that it supports a lot of Excel functions (not the VBA ones).

Before we get to the list of functions, here’s how to write the month name formula:

=TEXT([DateField],”dd”) &”/”& TEXT([DateField],”mmm”) &”/”& TEXT([DateField],”yyyy”)

or

=DAY([DateField]) &”/”& TEXT([DateField],”mmm”) &”/”& YEAR([DateField])

or better

=IF(NOT(ISBLANK([DateField])),DAY([DateField])&” “&TEXT([DateField],”mmm”)&” “&YEAR([DateField]),””)

Now here’s probably what your here for, a list of SharePoint Calculated Field/Column functions:
