Assumption Day, known as Zoline in Lithuania, is a significant religious holiday celebrated in Lithuania on the 15th of August each year. The day commemorates the belief in the Christian art of the Blessed Virgin Mary’s ascent to heaven. It is observed as a holy day of obligation within the Roman Catholic Church, which means the faithful are expected to attend mass. It is also designated as a public holiday in Lithuania allowing the Lithuanians to observe the event.

In Lithuania, Assumption Day is celebrated with faith and fervor. The festival is often marked by feasts, processions, and traditions that blend Christian and pagan influences. For instance, in rural areas, farmers honor the holiday by refraining from field work and instead celebrate with abundant feasting, music, and dancing. A notable tradition unique to Lithuania is that of blessing herbs and crops on Assumption Day. The blessed plants are believed to have copious powers and are preserved for use during less prosperous times.

An iconic event that takes place on Assumption Day in Lithuania is the pilgrimage to the Shrine of Our Lady of Šiluva. Every year, thousands of people undertake this pilgrimage, seeking forgiveness, healing, and spiritual fulfillment. The shrine, believed to be the site of an apparition of the Virgin Mary, serves as a potent spiritual symbol during the Assumption Day celebrations. This day provides a deep insight into the devoutness and unwavering faith of Lithuanians and signifies the intertwining of Catholic beliefs with Lithuanian traditions and culture.
