What about sampling dates and then checking to see if the requested date is available.
use strict;
use Date::Calc qw(Today Add_Delta_YM Month_to_Text);
my @today=Today();
my $months_back;
my @fetchDates;
while ( @fetchDates < 2 ) {
my @calcDate = Add_Delta_YM(@today[0,1],1,0,$months_back);
my $date_str = $calcDate[0] .'-'. Month_to_Text($calcDate[1]);
if ( &dateAvailable($date_str) ) {
push @fetchDates, $date_str
}
$months_back--;
}
print "Retrieving dates:\n".join("\n",@fetchDates)."\n";
sub dateAvailable {
my $date = shift;
# check site of date can be downloaded
return int(rand(2));
}
I used rand just to show how it would work

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
