Any way to change the day headings in Calendar?

[GB]

At the moment each column (in week view) is headed by the date in the format
'16 September'. Can I alter that to show 'Thurs 16 Sept' or something
similar? Also, can I have a bold heading for today's column?

Well, I found that Outlook uses the Windows default long date format for
that, which can be altered in the Regional Settings applet in Control Panel.
Ofc that affects lots of other programs too.
