The Danish equivalent of Pancake Day is known as Fastelavn and actually takes place on the Sunday before Shrove Tuesday - seven weeks before Easter Sunday.
It's an old tradition in Nordic countries and sees children dressing up in costumes to go trick-or-treating for money or a Fastelavnsboller - a sweet bun typically filled with jam or cream. Historically, they were made as a way of finishing dairy products before Lent began, when Christians would traditionally give up certain foodstuffs until Easter.
Children also play a game hitting barrels decorated with pictures of cats and filled with sweets, similar to a Mexican piñata. Whoever knocks the bottom section of the barrel off is declared the Cat Queen, while the person who takes off the final board of the barrel becomes the Cat King.
Lithuania
In Lithuania, the traditional Shrove Tuesday celebrations are known as Užgavėnės - a festival that marks the end of winter and the beginning of Lent.
At major celebrations in the country, an effigy of winter known as Morė is burnt while a staged battle takes place between Lašininis, who represents winter and Kanapinis, who represents spring - with Kanapinis always coming out on top.
