Etymology

from Latin Januarius "first month of the year," from Janus, a Roman god

Word Origin
Among the many gods worshipped by the ancient Romans was one named Janus. He was believed to have two faces, one looking forward and one looking back. Janus was associated with doors, gates, and all beginnings. Because of that, when the Romans changed their calendar and added two months to the beginning of the year, they named the first one Januarius to honor Janus. The English January comes from Latin Januarius.
