The Perl Advent Calendar, a yearly series of December articles about Perl modules, tools, and practices, running since 2000.
HN commenters note it as the original coding advent calendar, which inspired Advent of Code, and link its articles on tools like cpandoc.
Install cpandoc[1]. It's supercharged perldoc command.
It lets you explore the CPAN ecosystem without installing the modules.
$ cpandoc XML::Twig
[ ... documentation for XML::Twig ...]
[1] Coincidentally, today's Perl Advent article covers cpandoc (http://perladvent.org/2011/2011-12-15.html).
On day 14 of The Perl Advent Calendar Chris Prather continues yesterday's story, revealing how Santa's team used Critical Chain project management alongside No Estimates to identify dependencies and ship NaughtyNice 3.0 on schedule.

Historical note: the original coding advent calendar was the Perl Advent Calendar, started in 2000 and still going.

Advent of Code is awesome also of course -- and was certainly inspired by it.
There is also a separate advent calendar for Perl 5.
