Ireland

Wrenboys on Wren Day in Dingle, County Kerry, Ireland.

In the Republic of Ireland, the day is one of ten official public holidays.^[5] Its name is sometimes shortened to "Stephen's Day", particularly in informal contexts.^[6]

In Irish, it is called Lá Fhéile Stiofáin or Lá an Dreoilín, meaning the Wren Day. When used in this context, "wren" is often pronounced "ran".^[7] This name alludes to several legends, including those found in Irish mythology, linking episodes in the life of Jesus to the wren. People dress up in old clothes, wear straw hats and travel from door to door with fake wrens (previously real wrens were killed) and they dance, sing and play music. This tradition is less common than it was a couple of generations ago.^[8] Depending on which region of the country, they are called "wrenboys" and mummers. A Mummer's Festival is held at this time every year in the village of New Inn, County Galway, and Dingle in County Kerry. Mumming is also a big tradition in County Fermanagh in Ulster. Saint Stephen's Day is a popular day for visiting family members and going to the theatre to see a pantomime.^[9]

In most of Ulster in the north of Ireland, the day is usually known as Boxing Day, especially in Northern Ireland and County Donegal.^[10][11][12]

Wales

Saint Stephen's Day in Wales is known as Gŵyl San Steffan, celebrated every year on 26 December. One ancient Welsh custom, discontinued in the 19th century, included bleeding of livestock and "holming" by beating with holly branches of late risers and female servants. The ceremony reputedly brought good luck.^[13]

Catalonia, Balearic Islands, Valencian Country (Spain)

Saint Stephen's Day (Sant Esteve) on 26 December is a holiday in Catalonia. It is traditionally celebrated with a festive meal that includes canelons. The pasta tubes are stuffed with ground meat that may include the leftovers of the previous day's escudella i carn d'olla, turkey, or capó. In Catalan-speaking territories the day is also known as the Second Christmas Day or the Festa Mitjana. In the Valencia area a tradition is to eat with the mother's side of the family on 25 December, and on the 26th with the father’s side. Historically, the Catalan holiday on the day after Christmas may be related to the practical need for time to return home after a Christmas Day gathering and may date back to the days of the Carolingian Empire. Although this lacks historical evidence and may be construed as revisionism.

Italy

In Italy, Saint Stephen's Day became a public holiday in 1947, where previously it was a normal working day; the Catholic Church also celebrates it as a religious holiday, even if not as a precept, as it is in Germany and other German-speaking countries. The reason for the public holiday in Italy, not required by the Catholic Church despite the fame of the saint, is to be found in the intention of prolonging the Christmas holiday, creating two consecutive public holidays, which also happens in the case of Easter Monday, a non-religious holiday, but which only wants to lengthen Easter.^[14] Before 1947 the two days were working days, with banks and offices open.

Alsace and Moselle

Saint Stephen's Day (la Saint Étienne) is marked as a public holiday as part of its shared culture across the Rhine River with Germany.^[15][16]

Austria, Germany, The Netherlands, Czech Republic, Slovakia and Poland

Stephanitag is a public holiday in mainly Catholic Austria. In the Archdiocese of Vienna, the day of patron saint Saint Stephen is even celebrated on the feast of the Holy Family. Similar to the adjacent regions of Bavaria, numerous ancient customs still continued to this day, such as ceremonial horseback rides and blessing of horses, or the "stoning" drinking rite celebrated by young men after attending Mass.

The 26th of December is – as Second Day of Christmas (German: Zweiter Weihnachtsfeiertag, Dutch: Tweede kerstdag, Czech: druhý svátek vánoční, Polish: drugi dzień świąt – a public holiday in Poland, Germany, The Netherlands and the Czech Republic.

Republika Srpska

Saint Stephen is also the patron saint of Republika Srpska, one of two entities of Bosnia and Herzegovina. St. Stephen's Day, 9 January, is celebrated as the Day of the Republika Srpska or Dan Republike, though mainly as an anniversary of the 1992 events rather than as a religious feast.

Finland

The best-known tradition linked to the Stephen's Day (Finnish: tapaninpäivä) is "the ride of Stephen's Day" which refers to a sleigh ride with horses. These merry rides along village streets were seen in contrast to the silent and pious mood of the preceding Christmas days.

Another old tradition was parades with singers and people dressed in Christmas suits. At some areas these parades were related to checking forthcoming brides. Stephen's Day used to be a popular day for weddings as well. These days a related tradition is dances of Stephen's Day which are held in several restaurants and dance halls.

Bulgaria
