Traditionally, the Black Fast is undertaken during Lent; it is the early Christian form of fasting consisting of "eating only once a day, toward evening; nothing else except a little water was taken all day". This was the normative way of Christian fasting prior to the 8th century A.D. and in some localities, such as in India and Pakistan, many Christians continue observing the Black Fast on Ash Wednesday and Good Friday, with some fasting in this manner throughout the whole season of Lent. After attending a worship service (often on Wednesday evenings), it is common for Christians of various denominations often break that day's Lenten fast together through a communal Lenten supper, which is held in the church's parish hall in the public setting; in the home setting Lenten Suppers take place in the context of a family meal everyday during Lent (except on the Lord's Day). Throughout the entire Christian year, many Christians keep the Black Fast on Wednesdays (in memory of Jesus' betrayal) and on Fridays (to mourn the crucifixion of Jesus).
