G'day devbond,

"i need to find the first day of the first week of a month."

Firstly, that seems an odd way to ask this. I'm assuming, for a given year and month, you want to know what day (e.g. Sunday) the 1st of that month is. If that's not what you meant, please clarify.

There's a plethora of modules on CPAN that can do this type of thing; however, the builtin module, Time::Piece, can also do this and you already have it installed. So, unless you're already using some Date::*, Time::*, etc. module, Time::Piece is probably your best choice. Here's sample code: 

#!/usr/bin/env perl -l

use strict;
use warnings;

use Time::Piece;

# In 2 days it will be Tuesday, 1st October 2013
my $month = 10;
my $year = 2013;
my $day_name = Time::Piece->strptime("$year$month" . '01', '%Y%m%d')->
+fullday;

print "01-Oct-2013 is a $day_name";

Output:

01-Oct-2013 is a Tuesday
