Easter Saturday or Bright Saturday is the Saturday after the Christian festival of Easter, also called Saturday in Easter week. Holy Saturday is often incorrectly called Easter Saturday. Confusion is probably caused because they are both a week apart.
In Australia, however, the day between Good Friday and Easter Sunday is sometimes referred to as "Easter Saturday" by secular authorities. See also Public holidays in Australia.
On this day, the Paschal Artos, a large loaf of leavened bread which was blessed at the end of the Paschal Vigil on Pascha (early Easter Sunday morning), is broken and distributed to the faithful. This may either be done at the end of the Divine Liturgy, and given out along with the antidoron, or it may be broken at trapeza (refectory) before the festal meal.
According to the Supplemental Book of Needs, the fracturing of the Artos is done in this way: "After the Divine Liturgy, the Artos is carried, as is customary, to the Trapeza and "Christ is risen..." is sung three times, with reverences, and after "Our Father" has been said, and having blessed the food as usual, the Deacon says: "Let us pray to the Lord", and the Brethren respond "Lord, have mercy", the Priest says the following prayer over the Artos: “O Lord Jesus Christ our God, the angelic Bread, the Bread of life eternal, Who came down from heaven and nourished us on these brightest days with the spiritual food of Thy divine benefactions for the sake of Thy three-day saving Resurrection, also now look down, we humbly pray Thee, upon our prayers and thanksgivings, and as Thou didst bless the five loaves in the wilderness, do now bless this bread, that all who eat of it may be granted corporal and spiritual blessings and health, through the grace and compassion of Thy love for mankind. For Thou art our sanctification, and unto Thee do we send up glory, together with Thine Unoriginate Father, and Thine All-holy, Good and Life-creating Spirit, now and ever, and unto ages of ages. The Brethren: Amen. Having fractured the Artos as is customary, he distributes it to everyone before the meal
The Holy Doors in the iconostasis, which have remained open all of Bright Week are closed on this day before the beginning of the Ninth Hour. The Vespers (or All-Night Vigil, depending upon local usage) on Saturday night is chanted in the normal manner, rather than the Paschal manner. However, the Paschal troparion "Christ is risen..." is read (or chanted, if a Vigil) three times at the beginning. That Vespers is the beginning of Thomas Sunday.
Because the date of Pascha is moveable, Bright Saturday is a part of the Paschal cycle, and changes from year to year. Eastern Christianity calculates the date of Easter differently from the West (see Computus for details). In 2007 Bright Saturday fell on April 14 (April 1 Old Style), in 2008 it fell on May 3 (April 20).
