Today's name: January
January is an English month name which comes from the old god Janus, god of gateways and transitions. It last ranked in popularity in 1979 at #749, and in 2010 there were 23 baby girls named January. January can be shortened to Jan, Jannie, Jana, JJ, or Ary/Arie. The most popular namesake at the moment is January Jones, who named her son Zander Dane. Although January is seen as a feminine choice, all of the international variants are decidedly masculine. Like December (nn Ember!), January is more refreshing and unique than other month name choices like April and May, yet not as "out there" as October and July.
