What platform are you on? If linux GNU date will do this for you.

Otherwise - please goto our FAQ and read the 'date arithmetic' thread

Alternatively, if you have Perl in your system, then you can use the Date::Calc module -

Code:
$
$
$ # Date = 22-March-2010 in "YYYYMMDD" format
$ echo "20100322" | perl -M"Date::Calc qw(Gmtime Date_to_Time)" -lne '@x=unpack("A4A2A2A2A2A2"); print ((Gmtime(Date_to_Time(@x)))[6])'
81
$
$ # Date = 31-Dec-2009 9:10:11 AM in "YYYYMMDDHH24MISS" format; MM=month, HH24=24-hour, MI=minute
$ echo "20091231091011" | perl -M"Date::Calc qw(Gmtime Date_to_Time)" -lne '@x=unpack("A4A2A2A2A2A2"); print ((Gmtime(Date_to_Time(@x)))[6])'
365
$
