Origin and history of January

January(n.)

late 13c., Ieneuer (early 12c. in Anglo-French), from Old North French Genever, Old French Jenvier (Modern French Janvier), from Latin Ianuarius (mensis) "(the month) of Janus" (q.v.), to whom the month was sacred as the beginning of the year according to later Roman reckoning (cognates: Italian Gennaio, Provençal Genovier, Spanish Enero, Portuguese Janeiro). The form was gradually Latinized by c. 1400. Replaced Old English geola se æfterra "Later Yule." In Chaucer, a type-name for an old man.

also from late 13c.

Entries linking to January

Janus

ancient Italic deity, to the Romans the guardian god of portals, doors, and gates; patron of beginnings and endings, c. 1500, from Latin Ianus, literally "gate, arched passageway," perhaps from PIE root *ei- "to go" (cognates: Sanskrit yanah "path," Old Church Slavonic jado "to travel"). He is shown as having two faces, one in front the other in back (they may represent sunrise and sunset and reflect an original role as a solar deity). His temple in Rome was closed only in times of peace. Related: Janian.

Rio de Janeiro

literally "January River," named by explorer Amerigo Vespucci because he discovered it on Jan. 1, 1502, and so called because he incorrectly thought the bay was the estuary of a large river. See January.
