About the name Jan
Jan belongs to the German and Scandinavian tradition. Its roots are documented, even though its precise meaning is not recorded in the standard references — an honest gap we prefer to a confident guess.
In the United States, Jan first appears in Social Security records in 1902. It climbed to its best-ever rank of #247 in 1944, and in 2024 65 babies received the name — 22,355 in total since 1880. Those are the official counts, not estimates.
