IO SATVRNALIA is so last year, how about Merry Modraniht?
The Anglo-Saxon year begins with the Yule-tide feasts (Modranect, or Mother's Night), in which warriors make their vows for the coming year (the origin of New Year's resolutions). As well as celebrating Midwinter, Modranect also marked the birth of Ing (Proto-Germanic *Ingwaz, meaning "son"), one of the three sons of Mannus (meaning "man"), and the progenitor of all North Sea germanic people (Frisians, Saxons, Jutes, and Angles).
As the often-quoted Bede said, Modranect/módraniht was observed on the very same day as Christmas, although I am pretty sure it was observed all over december/january with the rest of Yuletide, and was only set to 24th/25th of December when Julian calendar was adopted.
The sons of Mannus (Ing, Irmin, Istaev) in the 1893 edition of the Poetic Edda. Some people say these three became known later as Freyr (aka Yngvi), Odin (aka Jormun), and Thor.
