As Star Wars fans go about their business this holiday season, they might hear an unusual salutation: "Happy Life Day!" For anyone who's never heard of Life Day, it's a Wookie holiday with a rather mortifying origin. While it's a holiday set in a galaxy far, far away on the planet of Kashyyyk, it does bear a passing resemblance to a popular Earth holiday as it involves singing, feasting, and gathering around a tree with lights and loved ones.
