Thanks all for the overwhelming response!! I cracked this one with the CPAN modules Date::Simple and Date::Range. I was able to get the dates in the format I wanted and put all of them in an array.

May be this implementation is a bit "noobish" or elaborate... but it worked! I will definitely make note of all your suggestions, and perhaps, may be get to use it when I face a similar problem in future.

Okay! Here's what I did :D .....

my $date1 = $ARGV[0]; my $date2 = $ARGV[1]; my ( $start, $end ) = ( date($date1), date($date2) ); my $range = Date::Range->new( $start, $end ); my @all_dates = $range->dates; my %hash=("01"=>"Jan","02"=>"Feb","03"=>"Mar","04"=>"Apr","05"=>"May", +"06"=>"Jun","07"=>"Jul","08"=>"Aug","09"=>"Sep","10"=>"Oct","11"=>"No +v","12"=>"Dec"); foreach my $numericDate (@all_dates) { while ( my ($key, $value) = each(%hash) ) { $numericDate =~ s/\-$key-/\-$value\-/g; } } my @tempArray; foreach my $reverseDate (@all_dates) { split (/-/,$reverseDate); my $correctFormat = $_[2]."-".$_[1]."-".$_[0]; push (@tempArray, $correctFormat); } print "\n@tempArray\n";

So, the output looks something like this:

$ ./test.pl 2011-12-10 2011-12-13 ============================== 10-Nov-2011 11-Nov-2011 12-Nov-2011 13-Nov-2011 14-Nov-2011 15-Nov-201 +1 16-Nov-2011 17-Nov-2011 18-Nov-2011 19-Nov-2011 20-Nov-2011 21-Nov- +2011 22-Nov-2011 23-Nov-2011 24-Nov-2011 25-Nov-2011 26-Nov-2011 27-N +ov-2011 28-Nov-2011 29-Nov-2011 30-Nov-2011 01-Dec-2011 02-Dec-2011 0 +3-Dec-2011 04-Dec-2011 05-Dec-2011 06-Dec-2011 07-Dec-2011 08-Dec-201 +1 09-Dec-2011 10-Dec-2011 11-Dec-2011 12-Dec-2011 13-Dec-2011 ==============================
Thanks a ton for all your suggestions!
