The myth associated with him is that he is a baby at the beginning of his year, but Baby New Year quickly grows up until he is an elderly bearded man like Father Time at the end of his year. At this point, he hands over his duties to the next Baby New Year.
In addition to being a mythical figure, the Baby New Year is sometimes a real person. The first baby born in any village or city in a certain year may be honored by being labeled as the official Baby New Year for that year. The official Baby New Year can be male or female, even though the mythical Baby New Year is nearly always male. Attempts to name an official Baby New Year for an entire country have sometimes been made, but generally there are multiple contenders and no single Baby New Year can be confirmed.
