On Friday after the flagellation Jesus Christ was crucified outside the walls of Jerusalem, and Sunday was resurrected. The time of the celebration of the resurrection of Christ established the First Ecumenical Council in 325 year: Easter is celebrated on the first Sunday after the first full moon of spring — between April 4 and may 8.
It is a holiday symbolizing the victory of life over death, the path from earth to heaven. Believers greet each other with "Christ is Risen! Truly, He Is Risen!", triple kiss and give each other painted eggs as a symbol of the redemption of human sins by the blood of Christ.
