Here's one way using DateTime.pm and DateTime::Event::Cron, though it does not take into account holidays and assumes Mon-Fri 8 hrs per day. <shrug> :
use strict;
use warnings;
use DateTime;
my $start_date = DateTime->now();
my $end_date = $start_date + DateTime::Duration->new(months => 2);
print $start_date->datetime, "\n", $end_date->datetime, "\n\n";
use DateTime::Event::Cron;
my $crontab = '0 0 * * 1-5';
my $set = DateTime::Event::Cron->from_cron(
cron => $crontab,
start => $start_date,
before => $end_date
# to include $end_date, use 'end' rather than 'before'
);
my @weekdays = $set->as_list;
print scalar @weekdays, " weekdays : ", scalar @weekdays * 8, " work h
+ours\n";
Cheers,
Matt

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
