December 15

Zamenhof Day honors the December 15, 1859 birth of L. L. Zamenhof, who introduced Esperanto as a universal second language. Esperantists worldwide organize gatherings, language workshops, and cultural events to promote Zamenhof’s vision of international understanding. Conferences and online meetings feature lectures on Esperanto’s history, its literary works, and modern applications. Schools and clubs host essay contests, music performances, and film screenings that showcase Esperanto’s cultural heritage. The day fosters intercultural dialogue, celebrates linguistic diversity, and encourages the growth of the global Esperanto community.
