Bolludagur is an Icelandic tradition that is part of the celebration of Shrovetide, which is the period leading up to Lent. Bolludagur, also known as "Cream Puff Day" or "Bun Day," typically falls on the Monday before Ash Wednesday.
On Bolludagur, it is customary for Icelanders to enjoy a special kind of cream-filled pastry called "bolla." These pastries are often round and fluffy, filled with whipped cream and jam. They can be coated with chocolate or icing on top. The tradition involves people indulging in these delicious cream puffs and sharing them with family and friends.
In Iceland, Bolludagur marks the beginning of the Shrovetide festivities, which include other days like Sprengidagur (Fat Tuesday) and Öskudagur (Ash Wednesday). During this period, there are various customs and events, including costume parades and the exchange of small gifts.
