Pretzel Sunday, known as Bretzelsonndeg, is celebrated in Luxembourg on the fourth Sunday in Lent, which can fall between March 1 and April 4. This day marks the midpoint of Lent and is also referred to as Laetare Sunday or Rose Sunday. A notable custom of Pretzel Sunday involves boys presenting pretzels or sweet pretzel-shaped cakes to girls they are fond of, symbolizing their affection. In return, if a girl reciprocates the feelings, she gives the boy a decorated egg on Easter Sunday. In leap years, this tradition is reversed, with girls giving pretzels and boys giving eggs. The size of the pretzel often indicates the strength of one's feelings, and even married couples partake in this exchange.
