Saint Stephen's Day (public holiday in Alsace, Austria, Catalonia, Croatia, the Czech Republic, Germany, Hong Kong, Italy, Ireland, Luxembourg, Poland, Slovakia and Switzerland), and its related observances: Father's Day (Bulgaria)

Father's Day is a day set aside for honoring one's father, as well as fatherhood, paternal bonds, and the influence of fathers in society. "Father's Day" complements similar celebrations honoring family members, such as Mother's Day and, in some countries, Siblings Day, and Grandparents' Day. The day is held on various dates across the world, and different regions maintain their own traditions of honoring fatherhood.
