You could change the locale of your bibliography and see if that solves
things. To change the locale, right click on your bibliography and select
"Edit Field...". You will see something like "BIBLIOGRAPHY \l 1033". What
you have to do is change "1033" for the value you wish to use. "2057" is
normally the UK one, but the whole list can be found at

Note that changing the locale might influence other strings in your
bibliography!
If changing the locale does not fit give you the result you want, you will
probably have to rewrite that part of the style which does the date
formatting. It requires some xslt knowledge though. If you post details
about the style you are using, I might be able to help you with that.
