Clean Monday, known as 'Καθαρά Δευτέρα' in Greek, is celebrated in Greece and Cyprus on the sixth Monday before Palm Sunday, marking the beginning of the Great Lent period for Orthodox Christians. This movable holiday has no fixed date and is observed fifty days before Orthodox Easter. It symbolizes the transition from feasting to fasting and is associated with the end of the Greek Carnival. Greeks celebrate Clean Monday with outdoor activities and picnics, referred to as 'koulouma,' and enjoy traditional Lenten dishes made from legumes, vegetables, grains, and seafood. A notable custom includes baking 'lagana,' a type of unleavened bread. The day is also a bank holiday in Greece, with many shops closed and businesses not operating.
