Second Sunday of Easter different from Sunday of Easter
The Second Sunday of Easter is the day that occurs seven days after the Christian celebration of Easter. Those churches which give special significance to this day recognize it by various names. In the Catholic Church, this day is generally known as Divine Mercy Sunday. Across Western Christianity more broadly, this day is also known as the Octave Day of Easter, White Sunday (Latin: Dominica in albis), Quasimodo (or Quasimodogeniti) Sunday, Bright Sunday, and Low Sunday. In Eastern Christianity, this day is known as Antipascha, New Sunday (or Renewal Sunday), and Thomas Sunday.Biblical account
The Second Sunday of Easter is the eighth day after Easter using the mode of inclusive counting, according to which Easter itself is the first day of the eight. Christian traditions which commemorate this day recall the Biblical account recorded to have happened on the same eighth day after the original Resurrection.
