Baby New Year is the Anthropomorphic Personification of the new year. This also makes him the Holiday Personification of New Year's Eve and/or New Year's Day by default. He also more generally symbolizes rebirth (i.e. the "birth" of a new year and the "death" of the old one).
Baby New Year is almost always depicted as a baby boy wearing nothing but a top hat, a diaper, and a sash across his chest displaying either the words "Happy New Year" or the year he represents. He also sometimes holds an hourglass or noisemaker. Oftentimes, he's not a genuine newborn and instead more closely resembles a toddler due to frequently standing on his own (as opposed to crawling or just barely walking) and having a small amount of scalp hair. Sometimes, especially in older depictions, he will be portrayed arriving by Delivery Stork.
