Biljana is a name of Slavic origin, specifically from the South Slavic branch. It is derived from the name Biliana, which is ultimately derived from the Slavic word 'bilja', meaning 'flax' or 'linen'. This name has been used predominantly in Bulgaria and among the Serbs and Croats. Biljana was a popular choice during the 20th century but its usage has since declined. It is considered a traditional, somewhat old-fashioned name in contemporary times. The spelling and pronunciation of Biljana can vary across different languages and regions. In Serbian Cyrillic, it is written as Бilјана, and in Serbian Latin, it is Biljana. Pronunciation typically follows the stressed pattern "Bi-LYA-na", with the stress on the third syllable.
No significant increase or decrease over time for the name Biljana since it only appears once in the annual birth records with five births in 1974.
