The commonly cited names of the reindeer are Dasher and Dancer, Prancer and Vixen, Comet and Cupid, and Donder and Blitzen. вЂў Many cities across the world celebrate the New Year. The celebrations usually include a firework's display, and other festivities. London, for example, has a major fireworks display along the River Thames, followed by a parade on New Year's Day.
