Many do not know that the origins of the month we know as "January" came from the Roman calendar month Januarius (January), named for Janus, god of beginnings and doorways.

Janus is the Roman god of gates and doors (ianua), beginnings and endings, and hence represented with a double-faced head, each looking in opposite directions. He was worshipped at the beginning of the harvest time, planting, marriage, birth, and other types of beginnings, especially the beginnings of important events in a person's life. Janus also represents the transition between primitive life and civilization, between the countryside and the city, peace and war, and the growing-up of young people.
