Ash Monday (Vibhoothi)
Clean Monday (Greek: Καθαρή 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.
The common term for this day, “Clean Monday”, refers to the leaving behind of sinful attitudes and non-fasting foods. It is sometimes called “Ash Monday”, by analogy with Ash Wednesday (the day when the Western Churches begin Lent). The term is often a misnomer, as only a small subset of Eastern Catholic Churches practice the Imposition of Ashes. The Maronite Catholic Church and The Mar Thoma Nasranis of India-Syro-Malabar Catholic Church are notable amongst the Eastern rites that employs the use of ashes on this day.
