Hey, been busy lately but I finally addressed the problem you pointed out as follows:

```#!/usr/bin/perl

use strict;
use warnings;

use Date::Calc qw(check_date Add_Delta_Days Monday_of_Week Week_of_Yea
+r Compress Today Date_to_Text Weeks_in_Year);

if (check_date(@ARGV)) {
# If there are 52 weeks in the year, I have odd Fridays off.
# If there are 53, I have even Fridays off.
my \$mod = (Weeks_in_Year(\$ARGV[1]) eq 52) ? 2 : 1;
+);
my (\$week, \$year) = Week_of_Year(@friday);
my \$present = Compress(@friday) > Compress(Today());
printf "You %s have %s off.\n",
(\$present ? "DO" : "DID") . (\$week % \$mod ? "" : "N'T"),
Date_to_Text(@friday);
}
else {
print "Usage.\n";
}

```   my \$mod = (Weeks_in_Year(\$ARGV[1]) eq 52) ? 2 : 1;
...
(\$present ? "DO" : "DID") . (\$week % \$mod ? "" : "N'T")

Hmmm. When \$mod is 1, % is always zero - and you "DON'T/DIDN'T" have off.

Hmm yeah, I wasn't thinking. This is a weird case, I'll have to think more about it.
