Juliane is a feminine given name of Latin origin, derived from the Latin 'Iulianus', which means 'youthful'. It is a variant spelling of Julie and Julia, both of which are also derived from the same Latin root. Juliane gained popularity as a standalone name in the mid-20th century, often used alongside its more traditional counterparts. In some languages, such as German, it is considered a more formal or sophisticated version of Julia.
"The name Juliane experienced a significant rise in popularity from the mid-40s to the late 60s, peaking around 1963 with 33 births. However, it has since seen a steady decline, with only 8 births recorded in 2017 and 5 in 2019."
