Historical re-enactors dressed as 1812-era French horsemen ride during a reenactment of the French Invasion of Russia in 1812, during celebrations to mark the Russian Orthodox Christmas in St. Petersburg, Russia, Jan. 7, 2013. Christmas falls on Jan. 7 for Orthodox Christians who rely on the old Julian calendar rather than the Gregorian calendar adopted by Catholics and Protestants. (Dmitry Lovetsky/AP Photo)
