Januariusz is in Origin.

Januariusz is the Polish form of Latin Ianuarius, an adjectival name meaning “of Janus” or “belonging to January.” It derives from the Roman god Janus, guardian of doorways and beginnings (Latin ianua, “door”), so the name carries connotations of thresholds, renewal, and the turn of the year.

The best‑known bearer is the 4th‑century bishop-martyr St. Januarius (Italian San Gennaro) of Naples, whose long‑standing cult helped spread the name across Catholic lands. In Poland, Januariusz appears sporadically in ecclesiastical calendars and older baptismal registers but has remained a rare, scholarly‑sounding choice. International variants include Latin/English Januarius, Italian Gennaro, Spanish Genaro, Portuguese Januário (feminine Januária), French Janvier, and East Slavic Yanuariy/Януарий; a modern English offshoot is the month name January. Related Polish names are not direct equivalents, so Januariusz stands apart as a distinctive, tradition‑laden option.
