Janus, derived from Latin, is an ancient Roman deity whose very name signifies 'doorway' or 'arch'. In Roman mythology, Janus is recognized as the god of beginnings and transitions, appropriately positioned at the gates of heaven and hel. He is typically depicted with two faces, one looking forward to the future and the other gazing back into the past, symbolizing his role as a guardian of doorways, bridges, and thresholds. The month of January, the first month in the Roman calendar, is named after Janus, reflecting his association with new beginnings.
"The name Janus saw its popularity peak in the mid-1950s with a high of 16 births recorded in 1956. However, it has consistently remained quite rare, with fewer than 10 births per year for most decades."
