December 9 is the day to start preparation of the lutefisk to be consumed on Christmas Eve in Sweden as well as Anna’s Day, celebrating all people named Anna in Sweden and Finland.
Researching this day, I found a great site, Behind the Name, which gives name days by country, etymology, popularity, and other interesting things about given names around the world.
