a: A message with a blank content is likely to be rejected or ignored. The
subject line is just for a brief description, and the detail (which is sadly
lacking in this message) should be in the message body.
b: Postings all in UPPER CASE are regarded as SHOUTING, and a breach of
netiquette.
c: Dates within Excel are stored as numbers, so in general it can't
distinguish between a date and another number. You may be able to
distinguish an integer from a non-integer number (which would represent a
date and time). You may be able to define a rule such as dates in the 21st
century or within another window.
d: If you are adding two dates, such as 22 Sep 2007 and 23 Sep 2007, do you
want the result to appear as 16 Jun 2115 or as 78695?

You may wish to reformulate your question?
