In Lithuania, the Second Day of Christmas is often regarded as an extension of Christmas Day and is intended to extend the spirit of love, kindness, and generosity. It is a day dedicated to spending time with family, visiting relatives and friends and giving and receiving presents.

Holidays like the Second Day of Christmas are deeply embedded in Lithuanian culture and traditions. The day is often marked by sharing traditional Lithuanian foods, singing Christmas carols, and enjoying the warmth of each other's company. Although the country is well known for its Christian heritage, the holiday is celebrated by both Christians and non-Christians, as it primarily focuses on family and community ties.

Lithuanians traditionally also pay a lot of attention to Christmas decorations, particularly Christmas trees which are often adorned with handmade ornaments. On the Second Day of Christmas, families traditionally layout a lavish spread that predominantly consists of twelve meat-free dishes, signifying the twelve apostles. Overall, it is an opportunity for Lithuanians to cherish their loved ones, continue the celebrations, and carry forward the spirit and joy of Christmas.
