The Second day of Christmas, also known as Boxing Day in some countries, is a public holiday in Romania and is celebrated on December 26th every year. This holiday serves as an extended celebration of the birth of Jesus Christ following Christmas Day. Traditionally, it is a day when employers give gifts to their employees, and when people give presents to postmen, dustmen, and other service providers.

In Romania, the Second day of Christmas is just as important as the first, and is marked by continuation of family gatherings and feasts. Romanian people traditionally prepare special meals and pastries for the two-day Christmas celebration. Many Romanians spend the day visiting friends and neighbors, and those of the Orthodox faith may attend church services. It is also common for carolers to continue singing traditional Romanian Christmas songs.

The Second day of Christmas in Romania is also associated with the celebration of Saint Stephen's Day. Saint Stephen is the patron saint of horses in Romania, hence horse parades and horse blessing ceremonies are typical. There are a number of regional customs associated with this day, but it is generally seen as a time to relax and enjoy the festive season with family and friends before heading back to work. All in all, it's a day to extend the joy and spirit of Christmas.
