In Serbia, Bulgaria and other Balkan Orthodox countries the feast is popularly known by a name meaning Little Lady Day, distinguishing it in the folk calendar from the Assumption or Dormition in mid-August, called Great Lady Day in the same regional tradition, and it has long served in rural Balkan folk custom as an informal marker for the end of the main summer agricultural labour season, the point at which the heaviest harvest work was traditionally considered complete and a shift toward autumn tasks began.
This folk seasonal marker sits alongside, rather than replacing, the feast's formal liturgical content honouring Mary's birth, illustrating a pattern found across many of the fixed-date saints' feasts and Marian observances covered in this atlas: a church calendar date fixed for strictly theological and liturgical reasons in late antiquity or the early medieval period frequently acquired, over centuries of rural use, a second and entirely practical life as a seasonal and agricultural marker for communities whose working year the church calendar came to structure well beyond its original devotional purpose.
The same "Little Lady" naming convention crosses the Catholic-Orthodox divide in the Balkans and along the Adriatic: Catholic Croatia keeps the feast as Mala Gospa, using an equivalent term to the Orthodox Balkan usage described above even though the two churches otherwise differ on the Marian feast's theological framing, showing that the folk name for the day spread across a shared regional culture rather than following confessional boundaries.
