Although the role of gift-giver on Christmas Day itself is assigned to the Christ Child, on the night before St. Nicholas Day Hungarian children traditionally place a boot on their windowsill waiting for Mikulás to come by and fill it with treats. In Hungary, celebrations begin with Christmas tree decoration and gift packaging during daytime on December 24, then comes a family dinner with traditional Christmas meals. In some parts of Hungary, a traditional supper called fish soup "halászlé" is served at Christmas Eve meal, although it is also consumed at other times of the year. The day is otherwise a fast-day.
