Anton's name day is widely celebrated, primarily on January 17th in countries including Bulgaria, Estonia, Finland, Norway, Sweden, and the USA. Further observances occur on June 13th in Germany and Slovakia, reflecting regional differences in commemoration. Finally, the name day is also marked on October 24th in Austria.
The name Anton is a firmly masculine name originating from the Roman family name Antonius, typically interpreted to mean "priceless" or "highly commendable." Historically utilized across Germanic and Slavic regions, it maintains a strong, sophisticated mood globally. In the United States, Anton has always been less common than its variant Anthony but is favored for its classic, international elegance. Its short, decisive sound projects a strong personality and professional tone. This European iteration carries centuries of history, connecting bearers to ancient virtues.
