Happy winter solstice! December 21 (or in some years, December 22) marks the winter solstice, the shortest day of the year. Solstices happen due to the tilting of the Earth on its axis. Did you know that below the Equator, it is summer right now? Where did I get all of this great information? From the World Book Online For Kids. You can access this great online resource for free; all you need is your library card!
