Easter Week is the period of seven days from Easter Sunday through the Saturday following.
In the Latin Rite of Roman Catholicism, Anglican and other Western churches, Easter Week is the week beginning with the Christian feast of Easter and ending a week later on Easter Saturday.[1] The term is sometimes inaccurately used to mean the week before Easter, which is properly known as Holy Week, and particularly confusing in this context is the secular usage of the term Easter Saturday to refer to the day known liturgically as Holy Saturday or Easter Eve (the day before Easter), rather than the Saturday following Easter.
