Hello Sec,

Sorry for the late reply, but I just noticed your reply.

Here is a sample of the same process and module by using French as everyone is providing you:?

#!/usr/bin/perl
use strict;
use warnings;
use Date::Manip;
use feature 'say';

Date_Init("Language=French");
say UnixDate(DateCalc(
         ParseDate("aujourd'hui"),
         $_ . " jours plus tard") , '%A') for (1..7);

__END__

$ perl test.pl
mardi
mercredi
jeudi
vendredi
samedi
dimanche
lundi
[download]

More information regarding the languages that the module can support Date::Manip::Lang.

Hope this helps, BR.
