Jaanus

Jaanus is an Estonian masculine given name derived from the Latin Janus, the ancient Roman god of beginnings, gates, and transitions, whose name is itself connected to the Latin word for door or passage. The Roman deity gave his name to the month of January, reflecting his association with new starts. Jaanus is the distinctly Estonian form of the broader name family that includes Johannes and its many European descendants, though in Estonian usage it stands as an independent given name rather than a direct variant of John. Related forms include Jaan, the common Estonian equivalent of John, as well as the Latvian Jānis and Finnish Janne.
