Januarius is the name of the Roman god Janus, who was the god of beginnings, transitions, gates, doorways, passages, time, duality, and endings. He was often depicted with two faces, looking forward and backward, symbolizing the past and the future.
The month of January was named after Janus because it was considered the beginning of the year in the Roman calendar.
Here's the breakdown:
* Janus: The Roman god of beginnings.
* Januarius: The Latin adjective form of "Janus".
* January: The English word adopted from "Januarius".
