Christmas Day or 'Kaledos' in Lithuania is a prominent holiday celebrated on the 25th of December, marking the birth of Jesus Christ. It is a widely recognized public holiday where families gather for special feasts and exchanges of gifts. Similar to the traditions of many Western countries, Lithuanians decorate their homes with Christmas trees, lights, and ornaments. But a unique tradition is the centuries-old practice of constructing detailed miniature nativity scenes, or 'szopka', which includes figures of baby Jesus, the holy family, shepherds, and the Magi.

The celebration of Christmas in Lithuania usually begins with the Advent season, the four-week period leading up to Christmas Day. Churches throughout the country hold special services and organize charity events for the less privileged. On Christmas Eve, families partake in the 'Kucios', a traditional meatless meal that symbolizes the Last Supper of Jesus Christ. This dinner usually consists of twelve dishes, representing the twelve apostles, including beet soup, herring, various types of fish, poppy milk and Christmas Eve biscuits, with each dish carrying its specific symbolic meaning.

As Christmas approaches in Lithuania, the spirit of goodwill is everywhere. People open their hearts to kindness and generosity, giving to charities, sharing meals with family and friends, and exchanging good wishes. Lithuanians also maintain the old tradition of caroling, with groups of people going from house to house to sing Christmas songs or 'Kaledines dainos', spreading holiday cheer. This holiday offers a unique blend of Christian and pagan rituals that highlight the authentic cultural identity of Lithuania.
