Easter, which will be observed on April 4, 2021, is the oldest and most important Christian festival. Many adults commemorate the holiday, which celebrates the resurrection of Jesus Christ on the third day after his Crucifixion, with prayers and fasting for 40 days before the event. For children in the US, Easter is largely about fun activities like seeking out candy-filled eggs, meeting the Easter bunny, and participating in spring parades. However, not everyone celebrates this all-important holiday with these traditions.
