Clean Monday (Greek: Καθαρά Δευτέρα), also known as Pure Monday, Ash Monday, Monday of Lent or Green Monday, is the first day of Great Lent throughout Eastern Christianity and is a moveable feast, falling on the 7th Monday before Pascha (Easter).
Clean Monday is a public holiday in Greece and Cyprus, where it is celebrated with outdoor excursions, the consumption of shellfish and other fasting food, a special kind of azyme bread, baked only on that day, named " lagana" (Greek: λαγάνα) and the widespread custom of flying kites. Eating meat, eggs and dairy products is traditionally forbidden to Orthodox Christians throughout Lent, with fish being eaten only on major feast days, but shellfish is permitted in European denominations. This has created the tradition of eating elaborate dishes based on seafood (shellfish, molluscs, fish roe etc.). Traditionally, it is considered to mark the beginning of the spring season. Kite flying is also part of the tradition, as it symbolises "trying to reach the Divine".
