John Chapter 20Mary Magdalene, Peter, and John find the tomb-The risen Christ appears to Mary Magdalene in the garden-He appears to the disciples and shows His resurrected Body-Thomas feels the wounds in Jesus' hands, feet and side-Jesus is the Christ, the Son of God.
Easter is a movable feast, meaning it is not fixed in relation to the civil calendar. The First Council of Nicaea (325) established the date of Easter as the first Sunday after the full moon (the Paschal Full moon) following the March equinox. Ecclesiastically, the equinox is reckoned to be on 21 March (even though the equinox occurs, astronomically speaking, on 20 March in most years), and the "Full Moon" is not necessarily the astronomically correct date. The date of Easter therefore varies between 22 March and 25 April.
