If you right click on your date field:

1.  Select Custom Style at the bottom of the date list

2.  Click on the Customize button.

3.  On the Custom Style input screen do the following:

     a.  Change the default order to DMY

     b.  Change the month format to "Mar"

     c.  In the Separators section change the SECOND separator to " "... you will have to type that in.  the drop down box does not have that as an option.

     d.  Put a formula in for the first separator (do this my clicking on the x-2 button.  the formula should be:

 

if Mid (ToText (day({@D}),0),2,1) in ["1"] then "st "
else
if Mid (ToText (day({@D}),0),2,1)in ["2"] then "nd "
else
"th "

 

That will give you what you want.

 

Kindest regards,
