It’s a traditional holiday for our Anglosphere cousins: apparently it originated as being an opportunity for the upper class to both shower largess upon the lower class, and reinforce class distinctions via some Lord of Misrule activities*. This is, of course, why we don’t celebrate the holiday ourselves; if Americans wanted to reinforce class distinctions our ancestors wouldn’t have moved.
Ach, well, it’s also an opportunity to spend those Amazon.com gift certificates that you got for Christmas. Have at it, and happy holiday!
*Admittedly, I’m basing this latter observation on a M*A*S*H episode.
