Easter is the most important annual Christian religious feast in the year . It is celebrated the date of Easter as the first Friday , Sunday and Monday after the full moon following the vernal equinox（春分）（21 March）. They are called Good Friday, Easter Sunday and Easter Monday respectively .
Many holidays have a religious origin. Two of the most important holidays in the western world, Christmas and Easter, both originated in the Christian religion. Christmas commemorates the birth of Jesus Christ; Easter, his death and resurrection.
The Easter story consists of two part: the Crucfixion and the Resurrection. When Jesus was 32, he was sentenced to crucifixion by the Roman governor. He was religious leader and the Romans thought he was too powerful. His hands and feet were nailed to a wooden cross and he was left in the sun to die. To ridicule him the Romans put a crown of thorns on his head. This day is remembered on Good Friday. After Christ died, some of his followers carried him to a cave to bury him. Two days later he appeared alive. This is called the resurrection. It is celebrated on two days, Easter Sunday and Easter Monday – the first Sunday and Monday after a full on or after March 21st.
Much of the religious significance of these holidays has been lost in the 20th century. At Easter some people go to church, but for many Easter are mainly associated with the Easter bunny, chocolate Easter eggs and new spring clothes.
Throughout the English-speaking world, many Easter traditions are similar with only minor differences. For example, Saturday is traditionally spent decorating Easter eggs and hunting for them with children on Sunday morning, by which time they have been mysteriously hidden all over the house and garden.
Other traditions involve parents telling their children that eggs and other treats such as chocolate eggs or rabbits and marshmallow chicks (Peeps) have been delivered by the Easter Bunny in an Easter basket which children find waiting for them when they wake up. Many families observe the religious aspects of Easter by attending Sunday Mass or services in the morning and then participating in a feast or party in the afternoon. Some families have a traditional Sunday roast, often of either roast lamb or ham. Easter breads such as Simnel cake, a fruit cake with eleven marzipan balls representing the eleven faithful apostles, or nut breads such as potica are traditionally served. Hot cross buns, spiced buns with a cross on top, are traditionally associated with Good Friday, but today are often eaten well before and after.
