Jerry: There's two functionality in the above.

First: How many of a particular DOW are in a
period. This is just a matter of dividing the
total days by seven then adding one if
needed. If a function were added for this,
then I imagine its more a part of
DateTime::Span rather than DateTime itself.

Secondly you ask about getting the weekday of
the month. There's already a function in
DateTime for this:
$dt-weekday_of_month();

Test it with this:
perl -MDateTime -e 'print DateTime-new( year
= 2003, month = 9, day =
20)-weekday_of_month()'

I already said this. :)

Yes - but if we add the above functionality to DT::Span I think we should also have 
weekday_of_span() or a similar method for finding your location relativity to the 
start of the span (and not just the current month).
