What is the meaning of the name Janus ?

Janus is Latin in Origin.

Janus is a Latin theonym-turned-given-name derived from Ianus, name of the Roman god of doorways, thresholds, transitions, and beginnings. Etymologically connected to Latin ianua “door, gate” and ianus “covered passage,” it conveys ideas of entry, departure, and duality - the god is famously two-faced, looking to past and future. The month January (Ianuarius) commemorates him, reinforcing associations with new starts.

As a personal name, Janus appears in medieval and Renaissance Europe, often as a learned or Latinized form adopted by scholars and clerics; examples include the Hungarian poet Janus Pannonius and the Dutch humanist Janus Dousa. It persists in limited modern use, particularly in Denmark and the Netherlands, while remaining uncommon in English-speaking countries. Spelled Ianus in Classical contexts, related forms include Italian Giano and the month-name Ianuarius/January. Not to be confused with Slavic Janusz, which derives from John (Jan/Ioannes) rather than the Roman deity.
