Hi,
You can use -d to request a date by string, but i think it only uses 'next' or 
'last'.
date -d "last month"
Fri Mar  4 21:00:09 PST 2005

date -d "next sunday"
Sun Apr 10 00:00:00 PDT 2005

You could check if next sunday is the current month:
date -d "next sunday"|awk ' {print $2} ...does it = $thismonth?
That would be a lot easier to check than checking every day.
