Jasna is of Slavic origin, specifically from South Slavic languages like Croatian and Serbian. It translates to "clear" or "bright", deriving from the adjective 'jasan', which means clear or distinct. The name Jasna was particularly popularized in Croatia during the 19th century by the prominent Croatian writer Ivan Mažuranić, who used it for a character in his epic poem "The Death of Smail-Aga Čengić". Today, Jasna is still widely used and appreciated throughout Eastern Europe.
"Jasna was quite popular as a baby girl name in 1980 and 1999 with ten babies named Jasna across those two years."
